Replacing rear struts on a VAZ 2114 - replacement, repair, installation

Taking into account the quality of Russian roads, coupled with the build quality of domestic cars, you need to be prepared for constantly occurring breakdowns in car parts. Even if you are lucky and your car is indeed equipped with high-quality parts combined with excellent assembly, natural shock absorption has not been canceled.

Nowadays, a car's suspension includes a huge variety of different parts: shock absorbers, springs, bearings and much more. Each part is responsible for certain functions, but safety is guaranteed only through the quality of the installed mechanisms and their proper operation.

Replacing the support bearing on a VAZ 2114

Failure of the strut support bearing on VAZ 2114 vehicles is very common. Many owners of these cars immediately go to a service station, where they have to pay a lot of money and waste time for a replacement. If you have the necessary tools, you can do all the work yourself without seeking outside help.

Supports

How to change supports

To replace, you will need to purchase front, left and rear airbags. Experts advise replacing the entire set during repairs, since after replacing one part, another one may break after a while. The average cost of parts is 2000 rubles. If you have the necessary tools, you can do the repair yourself and save on car service.

List of tools

To replace the pillows we will need:

• 2 good jacks;
• metalworking tools;
• scrap;
• steel rope;
• glue.

Tip: At some stages you will need to lift a lot of weight, so it would be a good idea to invite a neighbor or a fellow car enthusiast here.

Replacing the front airbag

The repair of each support has its own characteristics. Replacing the front airbag is carried out as follows:

1. Put the car in 1st gear or the handbrake so that it does not move.
2. To gain access to the support, remove the upper engine protection.
3. Raise the engine with a jack. To avoid damaging its lower part or other elements, place a wooden board underneath.
4. When we have freed the support from the load, we can unscrew the bolt that connects it to the bracket.
5. We unscrew the bolts connecting the pillow to the motor.

   
   Removing the bolt that secures the cushion to the engine

6. We remove the old part and install the new one.

Replacing the rear cushion

Here we will need a steel cable to make it more convenient to work with fasteners.

1. We hook up the gearbox with a cable and install a jack under it.
2. Slightly press out the bolt connecting the gearbox to the support.
3. Unscrew the nuts securing the support to the body.

   
   Loosening the nuts that connect the cushion to the body

4. Raise the gearbox and unscrew the nuts and bolts.

   
   Unscrew the bolt and nuts

5. We replace and reassemble in reverse order.

When replacing the side airbag, you will need to perform the same steps. If you have a large starter installed, it will need to be removed to get to the bolt. It is better to coat rubber products with a special protective substance - this will ensure a long service life of the parts. After completing the repair, do not forget to test the car. If during movement the knocking stops and the vibration becomes almost unnoticeable, then everything was done correctly.

HOW TO CHECK THE OPERATION OF A SUPPORT BEARING

The main reason why owners decide to carry out such repairs is an extraneous knock when driving over even minor uneven road surfaces. When such discomfort occurs, replacing the support bearing is not always the best solution. First you need to check its performance, because the problem may lie in other parts of the shock absorber.

Checking the functionality of this suspension element is quite simple:

1. open the hood;
2. place your palm on the support;
3. a partner rocks the car from side to side;
4. If a characteristic cracking or knocking sound is heard under the palm, the bearing must be replaced.

It is important to know that failure or wear of the support bearing results in accelerated wear of the struts and a violation of the wheel alignment settings.

Selecting new parts

“What should I replace the old ball joint with?” - a question that arises for many car enthusiasts when such a breakdown occurs. After reading the reviews of VAZ owners of the fourteenth model, we can highlight several reputable brands:

• Original element of the Lada Detail brand. It has an excellent price-quality ratio. It has a large number of positive reviews on the market, but has analogues in similar packaging. In order not to make a mistake when choosing, check the availability of the article 21100-2904192-86 on the package. The price of the product is about 350 rubles per piece.

• BelMag. Also a proven brand in the manufacture of ball joints and more. Most car enthusiasts prefer elements of this brand. There are no analog copies on the market, which is why the risk of purchasing a low-quality item is greatly reduced. Product code 1665, and the price is the same as the original, about 350 rubles per piece.

• Original. It produces parts not only for domestic cars, but also for foreign cars. One of the downsides is the large number of analog copies, so the risk of purchasing a part of poor quality greatly exceeds that of competitors. However, the mechanisms of this brand last much longer than others and this is due to the price of about 400 rubles. Article by which to search for the product RG2108-2904192-86.

Which component you choose is up to you to decide. The mileage from replacement to replacement depends only on your driving style and the quality of the road surface. When operating a car on poor-quality road surfaces, the ball joints fail after 50,000 km. And when driving in urban conditions at a measured pace, ball joints last up to 70,000 km. The ball joint can run longer, but as soon as the boot of the element breaks and dirt begins to get into it, the mechanism fails within a week.

If you contact a car service center with a question about replacing a ball joint, the average cost of work is about 600 rubles, which is almost twice the price of the product itself. This price tag is due to the complexity of the work, since the fasteners are located in such a way that they are constantly subject to corrosion and are difficult to unscrew.

Changing a ball joint with your own hands is not difficult; the work process does not take more than two hours, unless additional problems arise in the form of rusted fasteners. The repair is carried out without the use of specialized tools and can be carried out anywhere, without having to drive into a hole or overpass. The part itself also has a low price, which allows you to not spend much on repairs.

ESSENTIAL TOOL

A high-quality replacement of support bearings on a VAZ 2114 with your own hands requires a minimum set of tools to perform these tasks:

• Standard set of open-end and ring wrenches size 12-24;
• Steering rod puller;
• Standard auto jack;
• Coupler for shock absorber springs;
• A “19” wrench is used to remove the strut rod nut.

HOW TO CHOOSE A SUPPORT BEARING FOR A VAZ 2114 CAR

The modern automotive industry offers a huge selection of this type of spare parts. Almost every car shop will provide any support bearings for the VAZ 2114, of various quality and price categories.

For this car model, the following types of bearings are most often used:

• support bearing with non-separable rings. Its advantage is the presence of installation holes that do not require clamping flanges;
• Design with removable inner ring. It is used for increased rotation accuracy of the outer ring;
• A completely dismountable system is used for increased rotational accuracy of the inner ring.

Based on the design and the availability of financial resources, the VAZ 2114 front strut support bearing is selected, which will be most suitable in your particular case. Do not save money, since low-quality products are unlikely to last more than 10 thousand kilometers and the procedure must be done all over again. The approximate price of journal bearings ranges from $10 to $80, depending on the manufacturer and design. By saving on the purchase, you risk damaging the shock absorber struts, and then repairs will cost several times more.

HOW THE REPLACEMENT IS MADE

It’s immediately worth noting that many modifications of these cars have the same suspension. For example, replacing the support bearing of a VAZ 2115, VAZ 2114 and VAZ 2109 is absolutely identical.

Let's proceed directly to the repair itself. There are several ways to carry out the work:

1. removing the entire rack, with steering arms and other parts attached to it. In this case, the wheel tilt settings are saved, and you do not have to perform the wheel alignment again;
2. you can disconnect the strut from the steering cam and then dismantle the remaining parts.

FIRST METHOD

1. We dismantle the hub cap and unlock the CV joint
2. We unscrew the CV joint until it is completely loose, while the brake pedal should be in a clamped state.
3. Jack up the car and unscrew the wheel.
4. Unscrew and unscrew the tip nut and press out the pin.
5. Next, you need to dismantle the ball and free the brake hose from the shock absorber.
6. Loosen the strut nut and unscrew the three support fixation nuts. Then the CV joint is removed and the strut is dismantled.
7. Next, the spring is tightened, which is required before changing the support bearing on the VAZ 2114.
8. After this, we put everything in place until the car is completely assembled.

SECOND METHOD

1. We jack up the car and remove the wheel.
2. Then loosen the hub mounting clamp and remove the steering tip.
3. We dismantle the ball and remove the brake caliper.
4. Next, loosen the strut nut and tighten the spring.
5. We change the support bearing and put everything back together.

After completing the work, it is advisable to replace the strut mounting nut with a new one.

We change the racks ourselves

What could indicate a problem with the racks? Firstly, the presence of squeaking wheels as soon as the car begins or ends its movement. Secondly, if there is a knocking sound in the pad area. Third, leak detection. It’s worth noting right away that trying to repair the racks is useless.

This will not bring the desired result, and besides, a “patched up” stand may fail at the most crucial moment, and this is already a threat to life. Therefore, it is better to immediately throw out the damaged parts and replace them with new elements. The whole process is carried out using the following tools:

• jack;
• cotter pins, vices and puller;
• hammer, pliers and chisel;
• keys 13, 17, 19, 22, 24 mm;
• wheel removal key.

I would immediately like to point out that the quality of the final result will depend on how competent the repairman is. That is, knowledge is required not only about the structure of the car, but also about how to handle each of the above tools

If there is even the slightest doubt, then it is better to leave the matter in the hands of professionals. Replacement of the rear struts is carried out as follows.

1. The machine must be on a level surface. Its rear axle rises. To avoid a sudden stall of the car, it is recommended to secure it by placing additional supports under the wheels.
2. Next, the wheels are dismantled. The protection is removed from the top fastener. After that, using a 13 mm wrench, loosen the rod nuts and those that hold the body.
3. Then, using pliers, the cotter pin is unbent so that it can be removed.
4. Using a 19 wrench, unscrew the nut on the steering rod, remove the brake hose, for which the fastening nut is unscrewed.

After this, you need to unscrew the parts of the steering knuckle and pull out the stand in the direction of the arch. Replacing the front struts is done a little differently. It should be carried out by placing the car above the inspection hole.

WE CHECK THE QUALITY OF WORK PERFORMED

When doing the replacement yourself, some skill deficiencies may appear. Somewhere a nut was not tightened or any of the elements of the rack were installed much crookedly. In order to avoid getting into an unpleasant situation on the road in the future, it is necessary to check the functionality of all the mechanisms that you touched when replacing the support bearing.

First, let's rock the car and check it for extraneous knocks. Be sure to check the operation of the brakes, since the caliper was removed during replacement. If everything is normal, you can start operating, not forgetting to check the wheel alignment settings, since it is also very easy to knock them down.

The support bearing on VAZ 2108-2115 vehicles is replaced on average once every 40 thousand km. If you do not want to endanger the machine racks, replacement must be done for preventive purposes.

Possible malfunctions of the rear pillar and their causes

Noise and knocking in the car suspension. One of the possible breakdowns, indicated by noise in the suspension, could be:

• wear of the rubber bushings of the rear struts (rubber bands);
• breakage or settling of the strut spring;
• weakening or wear of the shock absorber eye bushings.

The car begins to drive sideways on the road - at speed the car deviates from the “course”, as a result, the driver needs to constantly direct the car, keeping the steering wheel at the ready.

Possible reasons for this phenomenon:

• “breakdown” of the suspension due to the destruction of the compression stroke buffer;
• rear suspension overload;
• settlement or breakage of one of the suspension springs;
• displacement of the rear axle due to wear of the bushings of the suspension arms or deformation of the arms themselves.

Frequent breakdowns of the rear suspension. The causes are:

• failure of shock absorbers;
• upset or spring breakage.

In the damping system of a car suspension, the spring performs a return function and it has to withstand different loads and compensate for the pressure of the body on the wheels, as a result of which there are frequent cases of its damage and deformation.

Replacing the support bearing on a VAZ 2114 with your own hands

When choosing a car, buyers often take into account the quality of the roads on which they will drive. The popularity of models such as the VAZ 2114 is due to the fact that they are better adapted to domestic road realities, and therefore allow them to “conquer” the roads of our country with lower repair and maintenance costs.

Support

It is always important to remember such a concept as depreciation. Jumping over bumps, hitting potholes, the car will bounce if the shock absorbers and suspension cannot work properly and dampen vibrations. In a suspension, every node and every detail plays an important role. And the support bearing on the VAZ 2114 is certainly no exception.

Rack types

Before choosing specific brands and models of racks, you need to figure out what interests you. There are 3 types of racks. They have quite different characteristics. You should select them depending on where you travel most often and how this happens.

1. Oil-based, sometimes called hydraulic, are quite soft. They are well suited for people who prefer a measured, not fast ride. And also for those who, for whatever reason, often drive on dirt roads;
2. Gas ones are tougher. They prevent the car from swaying at high speeds and when cornering. But, using them on a primer quickly leads the suspension to a deplorable state;
3. Gas-oil ones have average performance between both types of racks.

Thus, knowing your driving style and the roads you drive on most often, you can easily choose the most suitable shock absorber struts for your case.

Analogues. So, you have decided to replace your original racks with similar ones. Let's assume that you have already decided which type of shock absorbers is ideal for you. All that remains is to select a specific product and purchase it. It should be noted that there are several well-known manufacturers of shock-absorbing struts for the “tenth Lada family” on the market. Therefore, let’s take a closer look at all the proposed options. Their positive and negative sides.

What is this?

It is not uncommon for owners of the domestic “fourteenth” VAZ model to notice that a knock . The reason for its appearance is failed support bearings.

Support rod brand SS20

But you don’t need to start replacing right away. The first priority is to check the condition of the support. And only then take appropriate actions.

The support bearing is an element of the shock absorber strut located in the front suspension structure. Its job is to maintain the mobility of the connection between the body and the shock absorber of your car. If the bearing turns out to be faulty, mobility is impaired and a knocking noise occurs, which is difficult not to notice. Especially when it comes to bad roads.

Basic faults

Wear of the VAZ-2114 bearing is the main reason for replacing it. A knock in the suspension, which is heard when driving on a bumpy road or when turning, should alert the driver. Checking the bearing is simple: you need to grab it with your hand and rock the car; a knock that may appear indicates the need for repairs.

The dirt that is abundant on the roads is one of the causes of defects in the mechanism. The support is practically not protected from it.

It is worth checking the condition of the supports at least after 20,000 km.

If the knocking does not go away, then think about this: a completely worn bearing can break completely, and this will lead to the strut breaking through the hood. Repair costs will be completely different.

Replacing a bearing is not that expensive - about 500 rubles per part, 1000 rubles for a replacement at a service station.

The most popular bearings are ss20. They perform best under relaxed driving conditions, although some drivers complain about their harshness.

For a more sporty driving style, with sharp stops and fast accelerations, Acomi bearings have proven themselves well.

Don’t skimp on spare parts; try to buy support bearings from a trusted manufacturer. When choosing, you need to rely on your own driving style and the characteristics of the road surface.

Kinds

In analysis

There are several types of supports:

• A bearing with an integrated inner or outer ring. No clamping flanges are required for its installation. There are corresponding holes for installation;
• With detachable outer ring;
• With detachable inner ring;
• Finishing and cutting structure, the characteristic feature of which is its strong rigidity.

The name of the support bearing speaks for itself. This is something like a strut support on the front shock absorber, which is located in the area where it connects to the body. This arrangement indicates the axial loads that the support must withstand.

Diagnostics

To diagnose the current condition of the support element, you need to perform a couple of simple steps.

1. Open the hood and place your palm on the element, that is, the bearing. In this case, your assistant should rock the car. If a knocking sound is heard, then it should be changed immediately.
2. Disassemble the structure to clearly see that the element is faulty and needs to be replaced. It is important to note that the approximate service life of the support bearing on a VAZ 2114 is 40 thousand kilometers. This is the recommended mileage after which the element must be replaced, regardless of its current condition.

A faulty support can lead to quite tragic consequences, such as wheel alignment disorder, increased risk when driving at high speeds, and increased wear of shock absorber struts.

If you do not pay attention in time and do not take appropriate action to eliminate the breakdown, you risk completely destroying the suspension of your car. It is not uncommon for a hole to form in the hood from the pillar. As you understand, such problems entail significant financial losses.

Selection of racks

Tuning version of car suspension

The choice of shock absorber struts for a VAZ-2114 can often confuse the car owner, since in addition to the original there are a number of analogues that can also be installed, as well as a sports version. Let's consider which of all the racks are most suitable for installation on a car and are suitable for our rough roads.

Native racks

2108-2905001 and 2108-2905002 – original catalog numbers of front shock absorber struts for the VAZ-2114 family of cars. The average cost is about 2,000 rubles/piece.

Original shock absorber struts

Since the conversation is about which struts are better, we can conclude that original shock absorbers do not suit car owners. But why? It seems that the design engineers took everything into account when designing this spare part, but no, something is still wrong.

The first factor that puts native stands in a negative position is that their endurance leaves much to be desired. The shock absorber seal does not last its life on smooth roads , not to mention the fact that it has to constantly absorb potholes. Since the original struts are of the oil type, when accelerating over 120 km/h it begins to loosen, and at 140 km/h this becomes significantly noticeable.

It is these two problems that become the reasons that car owners begin to look for a replacement for the original part.

What's behind?

2108-2915003 and 2108-2915004 – original part numbers for the rear left and right shock absorber struts manufactured by AvtoVAZ. The average cost is 2000 rubles/piece.

Maybe analog is better?

Analogue racks are usually either a cheap replacement for the original, with the same characteristics, or an improved budget option.

In fact, many manufacturers of spare parts offer a wide range of products that have long been loved by car owners and are highly popular.

So, let's consider a possible option for installing analogues of the VAZ-2114 shock absorber.

Front struts

Shock absorber strut manufactured by Fenox

Rear pillars

Shock absorber strut manufactured by Finwhile

Particular attention should be paid to shock-absorbing struts manufactured by Monroe.

Monroe racks

As practice has shown, they cope well with the uneven roads of the country and also have high durability. Read more about the process of replacing rear shock absorbers here.

Sports and popular stands

Sports shock absorbers

As you know, many car enthusiasts install sports and semi-sports shock absorber struts on their cars to achieve maximum effect on the roads and maximum stability. They are more durable and absorb road imperfections much better than stock or analog struts.

There are a number of manufacturers who have proven over many years of work that parts can be not only high-quality, but also durable. So, let's look at which spare parts manufacturers offer high-quality sports shock absorber struts.

Popular solution - Kayaba

Shock absorber struts manufactured by Kayaba

“Kayaba” are legendary stands that have earned worldwide recognition. They are famous for their quality and durability. At the same time, the automobile spare parts market is filled with counterfeits of this manufacturer. Let's look at what racks the manufacturer offers for 2114:

• EXCEL-G is a gas strut that is filled with nitrogen. Mainly intended for everyday driving, without special loads.
• Ultra SR and Ultra GR are sporty shock absorber struts with increased stability.
• Premium is a new generation of hydraulically driven shock absorbers. High-quality production material increases long-term use.

ProSport - CIS is not lagging behind!

Racks produced by ProSport

A legendary CIS company that has long been making sports versions of parts for domestically produced cars. There are two options for installation on a car - gas (sports) and gas-oil (semi-sports).

SS20 - forward domestic manufacturer

Racks manufactured by SS20

Popular manufacturer of domestic origin. The main specialization is the creation of tuning parts for cars produced in the CIS. For the VAZ-2114 there are 4 options for shock absorber struts from this manufacturer:

• Highway . Rigid struts that maximize cornering when accelerating.
• Standard . This option becomes ideal for those who live in harsh regions. They tolerate extreme heat and frost very well.
• Comfort . A universal version of racks, and therefore they are highly popular among car enthusiasts. The design features are such that they grip the road surface properly and work well with any driving style.
• Sports . These are the toughest racks. This option is intended for tracks, as it ideally holds the car during sharp maneuvers at high speed.

Replacement

First of all, we recommend watching a training video about the replacement. This will allow you to broaden your horizons, clearly understand the replacement steps, and also consistently perform a similar procedure, thereby returning the shock absorbers and suspension to their previous functionality.

Structure

Replacing the support is performed in the following sequence of your actions.

1. Raise the car using a jack.
2. Unscrew the wheel nuts and remove them.
3. Remove the cover from the nut located on the hub.
4. Loosen the hub fastening.
5. Remove the steering linkage from the rack. To do this you will need a mounting tool and a hammer.
6. Now remove the ball joint and remove the mounting bolts.
7. The next step is to remove the brake caliper. To do this, the fasteners and brake hoses are first disconnected.
8. The stem nut must be loosened. There is no need to completely dismantle it.
9. Be sure to tighten the springs.
10. Unscrew the bearing fasteners. The stand, along with the support and the disk, is removed. You have to replace them with new ones.
11. The unit is being assembled with a new element. The procedure is performed in reverse order.
12. It is advisable to replace the nut with a new one and tighten it properly. Just calculate the force, since the fastening nut is often torn off.

Doing the job of replacing a support bearing yourself is not as difficult as you may notice. At the same time, it is extremely important to notice the primary signs of support malfunction in a timely manner and take appropriate actions to solve the existing problem.

Supports for rear shock absorbers VAZ 2114

201 customers chose this product

In the “standard version”, the shock absorbers are mounted in the rear suspension of the car using two rubber cushions. The basic requirements for the upper shock absorber mount are the same as for the upper strut mount, except for the need to turn the wheels. Obviously, such a mount does not provide the required properties in terms of noise, vibration insulation and energy consumption (since at full load, more than half the weight of the car falls on the rear axle). Suspensions of foreign cars use specialized upper shock absorber supports to solve these purposes.

In this regard, the developed upper shock absorber support for the rear suspension has no domestic analogues (protected by patent No. 43221). It performs a similar function as the upper support of the front suspension strut, but at the same time it is structurally simpler, since it does not have a bearing and bolts for fastening to the body.

The support serves to transmit the damping forces of the shock absorber and the elastic forces of the spring and compression buffer to the body, and is also a load-bearing element of the suspension.

The shock absorber's upper mount consists of a funnel-shaped outer housing, an inner housing consisting of a bushing and a shaped washer, and a rubber element surrounding the surfaces of both housings.

On the outside, the support has a seating surface for the support coil of the suspension spring. On the inside, the support has a cylindrical surface for installation in the body bracket. The inner housing of the support is located in the lower funnel-shaped part of the outer housing and forms the lower end of the support. The housing bushing has a mounting hole for the rear suspension shock absorber rod. The shaped washer welded to it with its outer part follows the contour of the outer casing.

The space between the housings is filled with a rubber element. In the upper horizontal part (in the area of ​​the supporting surface of the body) and the lower part of the inner surface of the support there are teeth - protrusions, which, when deformed, create a progressive characteristic. At the same time, the teeth are constantly involved in the work, and the amount of their deformation depends on the load on the spring. Additional fastening elements - a rebound limiter, consisting of a washer and a cushion, is designed to limit the forces that arise during the reverse movement of the wheel, and fixes on the body a pre-assembled unit consisting of an upper support, a shock absorber, a spring, a protective casing and a compression stroke buffer.

The support has no wear parts, so its service life is equal to the service life of the vehicle. It does not require maintenance or inspection, and the removal and installation of the shock absorber is greatly simplified.

Thus, the upper shock absorber supports of the rear suspension TM ASOMI have the following advantages:

allow you to get a high smooth ride of the car and have the ability to absorb high dynamic loads;

increase vehicle stability and controllability;

reduce overall internal noise by 1-4 dB;

increased service life.

Replace support bearings on a VAZ 2114 with your own hands

Taking into account the quality of Russian roads, coupled with the build quality of domestic cars, you need to be prepared for constantly occurring breakdowns in car parts. Even if you are lucky and your car is indeed equipped with high-quality parts combined with excellent assembly, natural shock absorption has not been canceled.

Nowadays, a car's suspension includes a huge variety of different parts: shock absorbers, springs, bearings and much more. Each part is responsible for certain functions, but safety is guaranteed only through the quality of the installed mechanisms and their proper operation.

The use of shock absorbers in a car

Their main task is to maintain the operation of the elastic suspension, that is, to reduce vibrations resulting from unevenness as much as possible. If it were not for the shock absorber, the car would be installed only on springs, which did not dampen vibration.

Driving such a car would be like cruising on a boat. Thanks to damping elements such as shock absorbers, the car will deviate from its natural position due to uneven roads, but will automatically return to its previous position. Without shock absorbers, the recovery time would be obviously longer.

However, comfort is not the only goal of the entire suspension system. Moreover, this is just a derivative of his actions, and not a priority. The main task is to ensure contact of the wheel with the surface, and therefore safety. If the system did not have an element responsible for damping, the car’s wheels could bounce off bumps. You don't need to explain that this is a very undesirable and dangerous effect.

This causes not only a temporary loss of control over the car, but also incorrect operation of electronic systems such as ABS. This system "releases" braking force when the wheel loses contact with the surface. The result may be that ABS will not brake the vehicle on rough roads. In this situation, it is better not to have any brake support system, because this system requires constant contact of the wheels with the ground to perform its functions.

What's more, faulty shock absorbers mean that suspension and braking components wear out faster and your braking distance increases. They also cause the headlights to be in the wrong position.

VARIETIES AND CHECKING THE CONDITION OF THE SUPPORT BEARING

Many owners of VAZ 2114 cars often encounter the problem of extraneous knocking in the struts, the main cause of which is the support bearing. If you suspect a fault in the support bearing, you do not need to immediately rush to replace it; first of all, check its condition.

Before assessing the importance of the support bearing in the overall assembly of the car, it is necessary to understand the structure of the suspension. In the assembly of VAZ models, hydraulic struts are used, the main function of which is to smooth out vibrations in the suspension spring during driving, and also to ensure the quality and safety of its operation.

The support bearing is a component of the front suspension shock absorber strut. Its function is to allow smooth movement of the connection between the shock absorber and the car body. If it malfunctions, problems arise with driving the car, and an unpleasant knocking sound occurs in the suspension, especially when driving on a bad road.

VARIETIES OF SUPPORT BEARING

• With inner built-in ring or outer built-in ring. For installation there is no need to use clamping flanges; in this case, holes are provided for installation.
• The outer ring is detachable.
• The inner ring is detachable.
• The finishing bearing has strong rigidity.

Type of support bearing

The support bearing has a self-explanatory name; it is something like a support for the front shock absorber strut, located in the area of ​​​​the connection with the car body. This arrangement provides for axial loads that the bearing can withstand.

To make an accurate diagnosis of a support bearing, it is necessary to carry out a number of simple manipulations:

• Under the hood of the car, you need to place your palm on the bearing. At this moment, the second person is pumping the car, the appearance of knocking indicates the need for an urgent replacement of the support.
• But, still, it is better to carry out the necessary procedures for removing and subsequently disassembling the bearing.

All VAZ models need to change their support bearings after 40,000 km.

A completely deteriorated bearing, in addition to knocking, disrupts wheel alignment; this factor creates a danger when driving and increases wear on the shock absorber struts. Those drivers who categorically do not want to pay attention to the malfunction of their own car increase the chance of complete bearing failure, which will result in a hole in the hood from the strut. And as a result, financial investments increase significantly. Think about whether this is a way to get away from the problem that has arisen.

Selection of racks

Tuning version of car suspension

The choice of shock absorber struts for a VAZ-2114 can often confuse the car owner, since in addition to the original there are a number of analogues that can also be installed, as well as a sports version. Let's consider which of all the racks are most suitable for installation on a car and are suitable for our rough roads.

Native racks

2108-2905001 and 2108-2905002 – original catalog numbers of front shock absorber struts for the VAZ-2114 family of cars. The average cost is about 2,000 rubles/piece.

Original shock absorber struts

Since the conversation is about which struts are better, we can conclude that original shock absorbers do not suit car owners. But why? It seems that the design engineers took everything into account when designing this spare part, but no, something is still wrong.

The first factor that puts native stands in a negative position is that their endurance leaves much to be desired. The shock absorber seal does not last its life on smooth roads , not to mention the fact that it has to constantly absorb potholes. Since the original struts are of the oil type, when accelerating over 120 km/h it begins to loosen, and at 140 km/h this becomes significantly noticeable.

It is these two problems that become the reasons that car owners begin to look for a replacement for the original part.

What's behind?

2108-2915003 and 2108-2915004 – original part numbers for the rear left and right shock absorber struts manufactured by AvtoVAZ. The average cost is 2000 rubles/piece.

Maybe analog is better?

Analogue racks are usually either a cheap replacement for the original, with the same characteristics, or an improved budget option.

In fact, many manufacturers of spare parts offer a wide range of products that have long been loved by car owners and are highly popular.

So, let's consider a possible option for installing analogues of the VAZ-2114 shock absorber.

Particular attention should be paid to shock-absorbing struts manufactured by Monroe.

REPLACING THE SUPPORT BEARING VAZ 2114

Once you are completely convinced that the bearing is faulty, it must be replaced.

Replacement is carried out in several ways:

1. When removing the disc.
2. Without removing the disc.

Changing the support:

1. The car must be raised using a jack and, having first unfastened it, remove the wheel.
2. Remove the cover from the nut on the hub.
3. We loosen the hub.
4. The steering end is removed from the rack using a hammer and a pry bar.
5. Unfasten the ball and unscrew the bolts.
6. We remove the brake caliper, before doing this we disconnect the fasteners and detach the brake hose.
7. There is no need to completely unscrew the rod nut, just loosen it.
8. The springs tighten.
9. The bearing mounts are disconnected, the stand with the disk and support is removed and must be replaced.
10. Install the stand in the reverse order.

Please note that if you need to replace the nut with a new one, it must be fully tightened. When following this recommendation, you need to act as carefully as possible so as not to tear off the nuts, because this problem occurs quite often.

Do-it-yourself repair work does not cause any difficulties; for this reason, the model of domestic cars is quite popular among motorists.

The support bearing is an absolutely ordinary part in a car, it doesn’t stand out in any way, but when the first malfunction occurs, it immediately informs the car owner by producing noise signals, be it a knock, a click during a maneuver or when there are defects in the road surface. The solution to this problem is to carry out the necessary diagnostics and detect the causes of the noise emitted, and then completely replace the support or rack.

But is it worth believing?

in any case, until you deliver it yourself you won’t know whether it’s worth it or not. I liked it, I noticed the difference with the stock bagels, well, it’s easier for me in this regard, because the sneakers cost 15 and the slightest added softness in the suspension is already felt.

So there is no need to take that topic as truth.

But no, last year I also placed Asomi in front of the defensive midfielders.

The struts are stock, they don't knock, they don't leak, we checked them.

further discussion disappears

You can’t even tell me about the non-flowing and non-knocking SAAZ, you’ve already heard and seen it, so the fact that you put Asomi on the obvious g@$but and didn’t sense the difference, excuse me, these are your problems, I think you understand what everything is for me, for some reason it didn’t even occur to me to put such a thought on the g @$but the stock of the Acomi strut, because it’s clear that you won’t get anything and won’t notice anything, since the support doesn’t live on its own, but works and gives the declared characteristics of a completely taken and working suspension.

Threat, I installed the Acomi supports in front on a new suspension (not Saaz struts) after a week of riding on the same suspension, BUT with the stock supports, I immediately noticed the difference with the Acomi. ease of rotation of the steering wheel, softness.

NAUexx

Here you see what’s the matter: initially the Saaz racks don’t work as they should be, this is a normal rack, plus from the factory the Saaz is soft to the point of disgrace, so it’s practically useless to catch the declared characteristics of the Acomi supports on these racks, and if we consider the option with a mileage Saaz, then here’s
my Saaz scribe, according to all yours according to the signs, it seemed to work, and they had only 15 miles on them, but when they were removed, I was horrified for some reason, the rods were shaking with dips, and in the rack it was so crazy that the balls were dangling, although it also looked dry and worked when pumping the car/ held.

How to properly replace support bearings

Before replacing the support bearing, you need to check it. After making sure that the support is worn, it should be removed. To replace, you do not need to unscrew the alignment bolts, so the alignment should not go astray.

Signs of a faulty support bearing

First, you should look at all the fasteners - different racks have different fastenings for support - some have hexagons, others have ordinary bolted “8” ones, etc.

You can replace the rack in two ways: with removing the disk - for some it is easier, without removing the disk.

To replace we need:

• Ties for springs (you should buy more expensive and more reliable ones, because cheap ones can easily burst, or the thread will be too “steep”.
• Steering rod (tip) puller - in the form of a pry bar and a hammer.
• Jack, assistant.
• New bearing.
• A set of keys.
