Simple replacement of the crosspiece and outboard bearing of the VAZ 2107

Today there are fewer and fewer classic cars on our roads, and over the past few years not a single one has come to me for repairs. Therefore, when a client showed up in the morning with an old seven and offered to replace the crosspieces and suspension, I could not refuse because of the memories that came back.

But this is all rhetoric, and today we have to replace the VAZ 2107 driveshaft crosspiece and, as well as a bunch of outboard bearings, we still have to disassemble. The main signs of wear on the crosspiece are a characteristic loud click when starting, as well as vibration.

What are the main parts of a cardan drive?

• Parts capable of changing the angle and length of the transmission are a splined coupling (5), as well as rigid hinges (9.7) and elastic (3). It's called a coupling. The role of the coupling is that it reduces the noise of the connection and angular torque is transmitted. Repair of the driveshaft is required if the coupling material is cracked and crumbled. Simply put, the clutch needs to be replaced.
• The cardan coupling consists of 6 rubber parts (30), with metal spacers (31) between them. These parts are tightly connected into a one-piece unit, so in case of failure, the most correct solution is to replace the coupling.
• The coupling is placed between the flanges (4,2). They are attached to it with 35 bolts.
• Intermediate support (6), which serves to reduce vibrations and various types of beating.
• The front shaft of the VAZ 2107 (5) is a pipe with splines installed by welding. There is a tip (40) at the front. One of the coupling flanges is located on it, and the rear splined end is located on the support bearing (6). The bearing itself is well insulated from dirt by seals. Repair of the driveshaft is necessary if the splines are worn out.
• The rubber pad (12) in which the bearing is located dampens vibration well. On it, the front shaft may move slightly.
• The intermediate cardan support is attached to the bracket (15).
• Important is the safety bracket (27), which prevents the shaft from falling out if the coupling fails. If this bracket was not there, then the cars would overturn at full speed, and such cases have happened before. In this case, repairing the driveshaft is impossible; replacement is required.
• The difference between the rear shaft (8) and the front “neighbor” is that it has a hinge fork at the ends.
• The hinge itself is an important element of the transmission; it consists of a pair of forks (23), one crosspiece (22) and, in a separate figure above, needle-shaped bearings (20) - there are 4 of them, rings (19) and oil seals (21). The bearings are pressed with a fairly large force of about 800 kg into the fork holes. They are non-separable; if they malfunction, they need to be replaced.
• The cross has the required gap, from 0.1 to 0.4 mm. Only within such limits is the crosspiece correctly centered. There are rings in five sizes and five different colors for proper alignment. Repair of the driveshaft most often consists of correcting these gaps and replacing the rings.

What is a wheel bearing and why is it needed?

The bearing consists of outer and inner rings, a cage and rolling elements.

The structure of all rolling bearings is the same, with the exception of the rolling elements, the type of which depends on the design of the vehicle.

Most often, single-row tapered roller bearings are installed on driven axles. This is due to the fact that they are small in size and durable.

However, they require careful installation and periodic adjustment, otherwise they quickly fail.

Double-row tapered roller bearings are installed on the drive axles, which can withstand a load twice as large as single-row bearings.

In addition, they have a closed design, so they can be used until they are completely worn out without maintenance.

The operating conditions of these bearings can be confidently classified as severe. And if you add frequent acceleration and braking, road surface defects and bad weather, it becomes obvious that you cannot skimp on the quality of this part.

During normal operation, the service life is 100-130 thousand km. Sooner or later on VAZ 2114, 2115, 2110 there is a need to replace the bearing.

Elastic coupling for cardan shaft

The driveshaft consists of two parts (front and rear), connected to each other by a articulated coupling (cross). This design allows you to avoid loads on the shaft while driving, when the body and chassis of the car begin to “play.”

The end of the rear shaft is connected to the axle gearbox, and the end of the front shaft is connected to the gearbox shaft. The connection to the gearbox is made through an elastic coupling, which is a kind of buffer for leveling shock and dynamic loads on the driveshaft and gearbox shaft.

The elastic coupling acts as a buffer, smoothing out dynamic loads

Flexible coupling location

The elastic coupling is located in the lower front part of the car on the rear side of the gearbox. You can see it if you remove the engine protection and climb under the car. The coupling is easily recognizable due to its hexagonal shape.

Read, it might come in handy: Which shock absorbers to choose for a car?

The clutch is located on the rear side of the gearbox in the lower front part of the car

Coupling design

The basis of the coupling is a cushion made of especially durable rubber. Along its circumference there are six steel bushings fused into rubber, through which the bolts connecting the cardan flanges and the gearbox secondary shaft pass. The coupling kit also includes a special tightening clamp, which is put on it during installation or dismantling.

The elastic coupling consists of a rubber base and six steel bushings located around the circumference

Diagnostics of elastic coupling faults

The coupling may fail as a result of:

• wear of metal bushings;
• body wear;
• rupture of the body.

In each of these cases, the malfunction will manifest itself in the form of body vibration and extraneous sounds coming from the gearbox.

The condition of the coupling can only be checked by inspecting it and assessing the size of the play between the flanges of the gearbox and cardan shafts. This is done as follows.

1. The car is driven onto an overpass or inspection hole;
2. The engine protection is removed;
3. The coupling body is inspected and the condition of the bolted connection is assessed.
4. By loosening the cardan, the presence or absence of play is determined.

If signs of wear or mechanical damage are found on the coupling body (the body is partially or completely torn), the part must be replaced. A slight play (provided the body is intact) is eliminated by tightening the nuts of the connecting bolts. If the play is large, the elastic coupling will have to be replaced with a new one.

What is a shock absorber

A shock absorber is a component of the suspension that acts as a damper for vibration impulses. The scope of work tasks for shock absorbers includes the following:

• elimination of vertical swing;
• ensuring vehicle stability while driving;
• ensuring good grip on the road surface.

As you can see, this part is very significant, and when it fails, it has the most negative impact not only on driving comfort, but also on driving safety, because faulty shock absorbers invariably lead to an increase in braking distance and worsen traction, which becomes very dangerous along the way.

In addition, when worn out, they cause rapid wear of other parts and systems, in particular the brake system components.

That is why it is so important to carefully monitor the condition of the suspension, and, after the working period has expired or in the event of a malfunction, replace the defective part with a new one.

We'll talk about this later, but for now let's figure out what kind of shock absorbers there are, and, since we decided to talk about such a domestic model as the VAZ 2107, which of the existing components are suitable for this car.

Types of shock absorbers

Today, three types of shock absorbers are used for VAZ cars:

1. Oily. This type of unit is suitable for calm, comfortable driving for drivers who primarily value order and regularity. They work well on city roads, where traffic speed is limited and there are no treacherous potholes or potholes. But, if you prefer speed or extreme driving on country roads, then you need to look for something else.
2. Gas-oil classic option. This option is ideal for speed lovers. The design of the device itself provides better protection against impacts falling on the lower part of the car during high-speed driving. True, such units are thirty percent more expensive than just oil ones, but the quality is much higher.
3. Gas-oil with variable hardness coefficient. When you want to drive on the roads of distant provinces without worrying that the road will turn into a nightmare, then you should give preference to a gas-oil shock absorber of increased rigidity.

It is also worth noting that both versions of gas-oil units guarantee better controllability and the ability to maneuver on sharp turns than oil units.

The quality of the components also depends on the manufacturer’s brand: each company tries to introduce technical innovations into one or another option that significantly improve the characteristics.

So, having decided to replace shock absorbers in order to improve the technical characteristics of the VAZ-2107 car, you can turn your attention to:

Suspension bearing for propeller shaft VAZ 2107

The suspension bearing (or idler bearing) is designed to ensure uniform rotation of the driveshaft while driving. In addition, it is an additional point for attaching the cardan and is included in the design of the intermediate (suspended) support. In fact, it itself is a support, since it comes complete with a bracket, with which it is attached to the bottom of the car through a transverse bracket.

The bearing design is based on the outer and inner races and seven steel balls

Hanging bearing design

The hanger bearing is an ordinary closed type ball bearing. It consists of an inner and outer race and seven steel balls. For mounting on the bearing housing there is a steel bracket with holes for bolts.

The suspended bearing is equipped with a special bracket for ease of fastening

Outboard bearing location

The bearing is installed in front of the spider at the end of the front of the driveshaft. It can be seen from the inspection hole in the axial recess of the bottom behind the exhaust pipe at its junction.

The VAZ 2107 suspension bearing is located in front of the crosspiece on the front of the driveshaft

How to replace an outboard bearing yourself

1. To properly replace the outboard bearing, first apply CV joint grease to the cardan splines, and then install the lower washer on the shaft.
2. Now we put on the suspension bearing, orienting the locking element upward (try not to distort).

1. Select a socket whose internal diameter is larger than the diameter of the splines. Place the mandrel on the end of the inner race of the bearing, then press the support into the stop until the washer.
2. Now we insert the plug onto the seating surface and press it in as described above.

Important to know: We assemble the cardan elements only according to the marks that were placed during disassembly.

1. Then we tighten the fork with a locknut and bend the edges into a special groove with a chisel.

What you need to replace tie rods and ends

To carry out this type of work you will need some equipment and tools:

• The first tool is a twenty-two open-end wrench;
• A puller that will help you remove the ball joint;
• Pliers;
• A hammer, this tool should definitely be in every owner’s home.

Symptoms of faulty steering rods

There are two symptoms that indicate that the steering rods of the VAZ 2107 are faulty:

1. The first reason is a knocking sound from the front suspension. Quite a bad symptom with serious consequences. This knocking noise is especially audible when the car is driven on bad sections of the road and at low speeds. It is worth noting that this symptom may also indicate other problems with your car. For example, some suspension elements, ball joints, stabilizer struts and more.
2. The second reason that may indicate this malfunction is when the free play of the steering wheel increases. This is noticeable to the naked eye when, when the steering wheel is turned, the wheel itself remains in place and does not move. This makes it very difficult to drive a car at high speed, and especially on bad roads.

If you want to check the serviceability of the steering rods on your VAZ 2107 yourself, there is a way by which you will not need to contact professionals to diagnose the car. You just need to put your car in a pit. Next, you will need to take this rod from below and try to sharply move it up and down, and if you manage to do this with your hands, then you should change the tips.

Next, let's move directly to the process that interests us, this is replacing the tie rod ends of a VAZ 2107 car.

Balancing the driveshaft

After disassembling and replacing any element, the driveshaft must be balanced. This is done on a special stand, so for balancing it is easier to contact the nearest car service center. The balancing itself consists of measuring and eliminating the imbalance on the three shaft supports. Its permissible value at a shaft rotation speed of 5500 rpm should not be more than 1.62 N*mm. The imbalance is eliminated by welding small weights (metal plates) onto the surface of the front driveshaft.

Read this, it may come in handy: Replacing the rear axle gearbox, changing the shank seal, installing a self-block

If vibration appears after repairing the driveshaft, you can try to balance it yourself. Naturally, there can be no talk of any accuracy here, and the balancing itself will be only temporary. This is done as follows.

1. Drive the car onto a viewing hole or overpass.
2. Inspect the driveshaft.
3. Conventionally divide the front universal joint into four sectors (if you imagine it in cross-section).
4. Find a small weight weighing 30-50g and attach it to the front of the shaft using tape or tape.
5. Drive on a flat section of road, paying attention to vibrations.
6. If the vibration does not disappear or increases, move the weight to another sector and repeat the checking process.

When the load is in its place, the vibration should stop, unless, of course, it is caused by an imbalance of the shaft.

Useful tips

To increase the service life of the VAZ 2107 driveshaft, you need to follow a number of simple recommendations.

1. Avoid excessive contamination of the driveshaft couplings.
2. Systematically check the tightness of the fastening elements and the presence of lubricant in the connecting units.
3. If shaft malfunctions are detected, do not delay repairs.
4. When purchasing spare parts for a cardan, pay attention to the manufacturer and compliance with GOST or ISO requirements.
5. After repairing the driveshaft, be sure to have it balanced at a service station.

Diagnosing a malfunction, repairing and replacing the suspension bearing and elastic coupling of the VAZ 2107 propeller shaft with your own hands is quite simple. This requires minimal plumbing skills, a standard set of tools and careful adherence to the recommendations of professionals.

How to change the cross

Before removing the driveshaft, mark its position relative to the rear gearbox and elastic coupling. To do this, simply place the risks on them and then, when installing the cardan in place, combine them.

• remove the exhaust pipe from the exhaust pipe to the main muffler (you don’t have to remove it);
• unscrew and remove the cardan;

  
  Unscrew the cardan from the gearbox

  
  Mark and remove the cardan from the soft connection

• make marks on the forks of the cardan joints (during assembly, they must be aligned);
• remove the retaining rings; Removing the retaining rings
• Use a puller or drift to remove the crosspiece. You can remove the cups by squeezing them in one direction or in different directions (this is more convenient in my opinion).

  Dismantling the cardan crosspieces

You don’t have to go on ceremony with the crosspieces, but there’s no harm in catching the cardan forks.

We carry out the assembly more carefully.

• before installing the cross, add a little grease Fiol-2U or No. 158 (or at least lithol) so that the rollers do not crumble;
• we insert the cross into the fork, put a cup with rollers on its end and slowly hammer it into place until a seat for the locking ring appears;

• install retaining rings;

  
  Assembling the VAZ crosspiece If the rollers fell apart during assembly, the retaining rings will not fit into place; you need to disassemble again and install the rollers in place, after applying lubricant.

• when rotating tightly in the crosspiece bearings, lightly tap the forks in different directions so that the cups move slightly apart, using a wooden spacer;
• Next, install the propeller shaft in place.

Before installing the shaft, clean and lubricate the splines.

Recommendations from professionals for repairing CV joints

In this subsection, we invite you to familiarize yourself with practical advice from professional craftsmen:

• If it is necessary to change the hinge, perform a complete replacement. The only exception may be the reinstallation of anthers and other small parts from this category. In addition to lubricants in the CV joint, you need to change all the clamps and, with a certain degree of perfectionism, monitor cleanliness during assembly;
• A hammer and a wooden stand are perfect for installing the CV joint in place. Carry out installation work carefully - movements should be smooth and not forceful. In other words, you place a wooden attachment against the part and knock until everything falls into place. If you do not use a “gasket”, there is a high probability of damage to the part, which will become unusable;
• Once the CV joint is installed, install the boot. First, use pliers to clamp the clamp onto the shaft. Equalize the pressure in the part - use a screwdriver to hook the edge of the boot and unscrew it. Now clamp the clamp from the outside. A plastic plug is placed at the end of the shaft.

All other steps are performed in reverse order, as during disassembly.

As a result, performing repair work when it is necessary to replace the VAZ 2109 CV joint may seem labor-intensive. If you have enough free time, try to figure it out yourself. Otherwise, it is better to turn to professional craftsmen. Any service station will replace your CV joint or boot in a short period of time, because this is a fairly common problem on any car.

Unlike the front, it has undergone virtually no changes. Here, just like on the first Soviet G8s, a semi-independent beam is used. It is attached to the body on hinges (fortunately, there are no “crabs” in the design). A helical spring with constant stiffness is used as an elastic element. To dampen vibrations and prevent swinging, two shock absorbers are used.

• High reliability. The design does not have additional levers, which, in addition, can bend when falling into a large hole.
• Energy intensity. The Lada Granta absorbs all bumps perfectly, especially if oil shock absorbers are installed at the rear.
• Cheap maintenance. Due to its simple design, this pendant can be rebuilt even with your own hands. And the cost of new rubber-metal elements is unlikely to empty the pockets of even the most stingy car owner.

The main difference between the “Grant” suspension is the wheel alignment angles.

Summarize

Now we can safely state that the replacement process is complete. As it turned out, the work did not cause any difficulties, but it did require stocking up on some special tools. Buy bearings for LADA Granta cars that are of only high quality and from trusted manufacturers in order to have confidence in your safety on the road.

A wheel bearing malfunction is a common failure during the operation of a technical device. The reason for premature wear is poor-quality road surface and aggressive driving style.

Front wheel bearing

Replacing a wheel bearing is done independently, without special equipment, experience, or skills. Subject to the availability of spare parts, the replacement process will take no more than an hour, without the cost of car service.

Weak points of the cardan

Most often, joints, crosspieces and bearings break on the propeller shaft. Mainly due to wear and tear. As a rule, the listed parts are designed for a mileage of 60-70 thousand km, but it is likely that it will be less. This value is influenced by:

• features of the car transmission;
• machine drive type;
• product quality;
• modes used when driving;
• travel conditions.

Sounds or vibrations that are unusual for a working driveshaft indicate problems among its constituent hinges, bearings and crosspieces. Especially if at the start of the trip or when changing speeds there are knocks or clicks.

If the mentioned components of the propeller shaft are worn out, it is recommended not to repair them, but to replace them with new ones. Moreover, such products are quite easy to install and are relatively inexpensive. The approximate prices for them are as follows:

• cardan joint – from 160 rubles;
• cardan shaft cross - from 280 rubles;
• cardan bearing – from 300 rub.

A car enthusiast with the necessary skills can replace such elements of the driveshaft independently. For those who are not “specialists” on this topic, it is better to entrust the process to car service specialists.

Lada Granta: wiring diagram for rear wiring harness devices

The rear part of the car wiring is responsible for the equipment of the stern and sides of the car. all additional equipment is connected exclusively through this part of the highways:

• 1/2 – contact group for the dashboard;
• 3/4 – direction indicators;
• 5 – handbrake indicator;
• 6 – rear window heating contact;
• 7 – interior lamp;
• 8 – indicator of the driver’s seat belt position;
• 9 – cargo compartment illumination lamp;
• 10 – fuel pump drive;
• 11/15 – aft dimensions for the left and right sides;
• 12 – trunk lid lock drive;
• 13 – button for turning on the interior lamp;
• 14 – additional stop chain;
• 16-19 – door terminal blocks for the rear left, rear right, front left and front right doors;
• 20 – airbag control drive;
• 21 – contact group of license plate lights;
• 22 – on the dashboard;
• 23/24 – rear speed indicator sensors;
• 25/26 – seat belt pretensioners;
• 27 – group of dashboard contacts.

Vibration

Vibration occurs at speeds of 60-80 km/h and 90-120 km/h. The solution is to balance the cardan.

The vibration started suddenly at a certain speed and is only increasing. Possible solutions to the problem:

• It is necessary to check the crosspieces for play. If there is a malfunction, replace worn hinges.
• A small foreign body got on the body of the cardan flanges and the receiving flanges of the car.
• Play in the splines. The solution is to replace the spline connections.
• Corrosion or separation of balance plates.
• The pipe was bent when the bottom hit a hard object. Solution: if the deformation is less than 1.5 mm, then straightening it using a hydraulic press; if more, replace it.

Keep in mind that the car may vibrate and not because of the driveshaft. If vibration occurs at the same speed, then you need to look for the problem elsewhere.

What faults occur in this connection?

Typically the bearings will tell you when they need to be repaired or replaced. The sound of the outboard bearing indicates a failure. It can send the following signals:

1. Various knocks and noises, such as humming, buzzing or crunching;
2. Vibration, such as beating or jerking;
3. Play of the outboard bearing if it is subject to visual inspection.

If you hear that the suspension bearing is humming, you need to contact a car service as soon as possible.

As a rule, such elements of the driveshaft do not fail on their own. They break for the following reasons:

1. Natural wear of the element

   structures, gradual destruction of the rubber that holds the bearing.

2. Features of operating conditions, for example, low or high temperature conditions, contact with dirt and dust on the bearing, movement over rough terrain, hard gear shifting, increased loads.
3. An installation error that can easily be made if an inexperienced person is working.
4. Reduced quality characteristics of the components used. The fact is that the installed spare parts must be original or have proven themselves in the market.

Important! If the driver tries to exclude the maximum number of reasons during operation, then he can rest assured that the part will serve him for a very long time.

Of course, most often the most loaded elements fail: the universal joint and bearings. There are reasons for this: lack of necessary lubrication in the bearings and defects in the production of crosspieces. In the USSR, there was a terrible shortage of crosspieces: there is no crosspiece - the transmission is faulty - the car is stuck. Repairing the cardan shaft often cost a week's family budget, and replacing the crosspiece (or rather, the need for it) led many to despondency.

More rare transmission malfunctions of the VAZ 2107:

• Damage and misconfiguration (hitting rocks when driving in the mountains);
• Abundant amounts of dirt in parts and bearings;
• Failure of flanges, splines and couplings under load.

For lubrication, maintenance, if a part needs to be replaced, first of all, you need to properly remove it from the car and put it back. Repair of the driveshaft is also possible only after removal.

conclusions

Replacing the steering tips on a VAZ-2114 car is quite simple, but the process itself can take a lot of time and effort, since the fixing nut will not always be unscrewed easily. If the described process seems complicated to the motorist, then you need to contact a car service center, where they will always help with replacement. Separately, it is worth noting that the chassis parts must be changed on time to avoid the tragic consequences described in the article.

Diagnostics

If your problem is formulated as “broken outboard bearing,” you should contact a specialized service center for diagnostics in order to accurately identify the breakdown and find out its cause.

When carrying out such a procedure in car services, they take into account the fact that the first sign of natural wear of such a part is vibration, as well as a knocking sound in the area of ​​the driveshaft at the moment when the car starts moving. If previously there were no problems with balancing the axle, but the knocking still appeared unexpectedly, then the first thing you should do is check the outboard bearing. The diagnostic procedure in car services is carried out in the following order:

1. First, the machine is installed on an overpass, lift or inspection hole.
2. Next, they find the driveshaft itself under the bottom. First of all, mechanics

   check the play. To do this, move the part by hand in the axial direction. Free movement in such a situation is unacceptable.

3. Next, the diagnosticians rotate the cardan and listen to how the bearings behave. If there is vibration, rattling, knocking, or rolling, the part must be replaced immediately.
4. The next step is to inspect the body of the part. The degree of tightness of all bearing mountings is checked. Even the slightest leakage of lubricant is not allowed.
5. Then the car service workers pay attention to the bearing bracket. The fastening must be reliable.

Important! Such an algorithm allows you to fairly accurately determine whether the outboard bearing is in good condition or requires replacement. It is best that the described procedure be performed by an experienced person who is not the first time to see a faulty outboard bearing.

Converting the valve from a washing machine to 12 volt DC power supply

Electric valves are required to automatically control various hydraulic systems. Finished products are quite expensive. Let's look for a cheaper solution.

Recently, amendments to the traffic rules were introduced in Russia, one of which is: driving during the day with low beam headlights, fog lights or daytime running lights on. Now you need to drive with lights on during the day. Driving with low beams or fog lights on additionally creates a load on the generator, reduces the service life of the lamps, and also increases fuel consumption (more than 0.5 liters per 100 km). Therefore, it is better to drive during the day with the running lights turned on, the light-emitting element of which is LEDs, which consume much less power than incandescent lamps. You can buy DRLs, or you can make them yourself from scrap materials.
