How to change silent blocks on a VAZ 2106

Why do silent blocks need to be changed over time? There are several reasons for this:

Over time, rubber loses its elastic properties and begins to crack.
During use of the machine or during its maintenance, oil got onto the silent block.
Incorrect installation of the part.
Driving on very bad roads, of which there are a great many in Russia.

Everything is diagnosed quite simply. The first thing that should alert you is the deterioration in the responsiveness of the steering wheel. But this may not be the case only, let’s look further. The second sign of dead silents, the wheels are standing like a house. On the pit or on the lift, check the integrity of the rubber bands (they should not have cracks and they should not be squeezed out). You can take a crowbar or a pry bar and try to move the levers. They should not have free movement (should not dangle).

Replacing silent blocks of the lower arm

By its design, the rubber-metal element is made in the form of a non-separable part, which is non-repairable and only changes if it breaks. To carry out repairs, you need to prepare the following list of tools:

silent block remover;
ball joint remover;
keys at 13, 19, 22, 24;
hammer;
chisel;
mount;
lubricant (for example, WD-40);
jack.

Removing the lever consists of the following steps:

We jack up one of the sides of the car and remove the wheel.
Unscrew the fastening elements of the shock absorber and remove it.

Dismantling and installation of rubber-metal elements is carried out with one puller, and only the position of the parts changes.

Replacing joints without removing the lower arm

If there is no time or desire to completely disassemble the suspension, then you can replace the silent blocks of the lower arms without dismantling the latter. Having jacked up the front end on the desired side, perform the following steps:

We place a wooden stop under the lower ball joint. Its height should be such that when the jack is lowered the wheel does not hang out.

Preparing instruments for the replacement procedure

Replacing VAZ 2106 silent blocks begins with the acquisition and preparation of tools. The main thing is that the tool fits in size and is comfortable to use. What will still be useful in order to replace the silent block will be needed:

Device for changing rubber-metal hinge.
Tool for removing ball joints (for removing the upper arm
).
Tool for dismantling the steering wheel end (an irreplaceable thing when unpressing the distant steering wheel ends).
Jack.
Twenty-two and twenty-four millimeter wrenches (open-end, socket).
Thirteen millimeter wrench (cross-cut, socket).
Set of mounts.
Hammer.
A thin chisel (it must be very sharp, since the lower silent blocks are often glued to the lower arm under pressure, and to avoid removing the arm, you can use a chisel).

Replacing the lower silent blocks of a VAZ 2107 without a puller.

Since silent blocks play a very important role in the life of a car, and changing them is a rather complex and time-consuming process, there is no need to try to save money - you need to buy high-quality branded hinges. Don't know which one to take, rubber or polyurethane? Preferably polyurethane ones, but it should be noted that they are not cheap.

Replacing silent blocks VAZ 2106

The silent block is installed on the car's suspension arms; it is one of the important elements of the suspension. The silent block consists of two metal bushings and rubber inserts.

Photo of the car's lower suspension arm. Number 1 shows the ball joint, 2 - the lever, 3 - the axis of the lever (square in cross section), 4 - silent block.

Where is the silent block located?

The silent block connects the torque rod mounting elements, shock absorber mountings, anti-roll bar mountings, gearbox mountings, beam supports, and rear suspension rods.

Why do you need a silent block?

The silent block exists in order to perceive and dampen vibrations transmitted from other elements of the vehicle’s suspension. The silent block design allows it to perceive and absorb vibrations in all planes simultaneously; the silent block can withstand radial, axial and angular loads.

Which element of the car's suspension bears the heaviest load? The answer is silent block. That is why silent blocks wear out quite quickly. If the silent blocks are heavily worn, the car's wheels become uneven or come together. Wheel alignment in this case is a useless exercise, and besides, the money is simply wasted. Replacing silent blocks is quite difficult, especially if you are doing this car repair process for the first time.

Replace silent blocks

This can be done both in a car service center and at home. Now technologies have emerged for restoring worn silent blocks; restoration takes place using special equipment - vulcanizers. Restoring old silent blocks is cheaper than buying new ones.

How much does it cost to restore a worn silent block? In Russia, in car services where there are special vulcanizers, they restore worn silent blocks at a cost of 700 to 1800 rubles.

How to replace silent blocks on a VAZ 2106? To replace silent blocks on a VAZ 2106, you will need the following tools: 13 keys (two pieces), a 22 key, special devices for removing and installing silent blocks on the lower arm of a VAZ 2106. Instead of special tools for removing and installing silent blocks on the lever, you can use bushings with an internal diameter larger than the diameter of the silent block and such a length that you can install a washer on the lever axis and screw on the nut. These are tools if the levers have already been removed. And in order to remove the suspension arms of a car, you need to put the car on a jack, remove the wheels, free the fork from the ball joints, and free the lever from the beam.

The procedure for removing silent blocks from the lever:

1 clamp the suspension arm axle in a vise

2 unscrew the bolts from the lever axis on both sides

3 Next, we use a special device for removing silent blocks or a regular bushing: we thread the bushing into the lever axis and, by tightening the nut, press out the silent blocks. The supporting part of the bushing should rest against the lever.

4 after pressing out, pull out the lever axis with the silent block

5 then, remove the silent blocks from the lever axis, leaving the second washer

6 insert the lever axis into the bushing and also press out the second silent block

7 carry out a visual inspection of the suspension arm to determine its suitability for use in operation

8 installation of silent blocks is carried out in the reverse order. To press in new silent blocks, we rest the bushing against the outer race of the silent blocks. Check tightening of the lever axle nuts after installation on VAZ 2106 vehicles.

You can diagnose silent blocks

Requirements for simple DIY diagnostics of silent blocks:

Raise the car (with a jack or lift)
Visually inspect defects in rubber inserts
Check the behavior of the lever when swinging
Listen for knocks and play.

The main signs of a malfunction of the silent blocks of the front levers are the constant drift of the car off course and uneven wear of the tires. Having noticed these features, do not rush to grab your head and wallet. Try to figure out the problem yourself first. Do-it-yourself diagnostics of silent blocks is quite simple.

To do this, just use a lift or jack. On a suspended car, the ball joints are disconnected and there you have it, the condition of the silent blocks is clear in full view. The suspension arm should not fall. When swinging vertically, it should spring back and return to its original position. Actually, this is his job. The silent block bushing should not rotate relative to the lugs. If any of this does not correspond to the real condition, there are signs of wear on the silent blocks of the front levers.

At the same time, visually inspect the suspension joints for possible rubber peeling. Rubber can also crack or swell at hinge joints. Diagnosis of silent blocks requires paying attention to the presence of play. As a result, the car may require urgent replacement of silent blocks. Remember! A belated replacement destroys the contact points of the hinges, and this is fraught with a complete replacement of the elements of the front suspension arm.

In the design of a car suspension, the connection of some components with each other to the load-bearing part (body) is carried out using rubber-metal hinges - silent blocks. The main task of these rubber products is to dampen vibration and prevent its transmission between suspension elements.

The silent block is an important element of the suspension design, but at the same time it is also its weak link.

The presence of a rubber component in its design makes this element not particularly durable. In addition, it is subject to repair, which classifies these hinges into the category of consumables, which, after exhausting their service life, are simply replaced.

The process of replacing silent blocks

To replace the silent blocks of the lower control arms on VAZ classic cars, you need to drive the car into a garage or pit box, or use a lift. The fastening points of the parts are pre-treated with WD-40 lubricant, which must be left for a while to facilitate the removal of these parts. When processing, you need to make sure that the lubricant gets into the attachment points of the unit, this will make dismantling easier. During operation, the silent block may sour, and if it is not treated in advance, it will be difficult to remove it using a pry bar and a sledgehammer.

If the car is parked in a pit, it is jacked up under the beam to relieve the load from the wheels, supports are placed under the levers, and a safety block is installed under the jack to avoid injury in the event of the car falling off the supports under the levers. Using a 22 wrench, unscrew the nut holding the silent block in the lower arm. If the nut is soured, you can use a piece of pipe as an additional lever by placing it on the wrench. It is better not to throw away the original nuts, since new ones are often of poor quality and the threads break off, so sometimes it is better to install old ones. The same can be said about old washers, which are made of thick, durable metal, while the washers that come with new silent blocks are thinner and can be significantly deformed when tightened, which is unacceptable.

To dismantle the front silent block, the mount must be positioned so as to rest against the bolt of the beam and press forward towards the rear of the car. Since the pressing force on the mount will be small, it is necessary to periodically hit the lever near the silent block with a hammer, while pushing against it to create tension. After the silent block comes out of the socket, remove it, pushing it with a pry bar. In case of severe souring, the procedure will have to be done by two people: one person pulls the lever with a pry bar, the second knocks the silent block out of its socket.

Next, the silent block of the front beam is replaced; for this, the axle is lubricated with nigrol and a new part is put on it. Using a pry bar, the lever is raised so that the silent block can be guided into the socket. After this, an extension made of a thick-walled pipe of suitable size is put on it, which must be carefully hit with a hammer until the silent block sits in place. We hold the mount by the mounting bolt and press the lever, continuing to hit the mount with a sledgehammer until the part sits in the socket all the way to the stops.

We change the lower silent blocks from the reverse side, for which you first need to knock the short rod end off the steering column so that it does not interfere with work. Using a pry bar, pressing it against the nut, we move the lever in the same way to release the silent block. Similarly, we hit the lever with a hammer, pulling it with a pry bar until the silent block comes out of its socket, then push it with a pry bar until it is completely removed. Installation of a new silent block is carried out in the same way as in the front part of the lever, using an attachment made from a tube and a hammer, the axle and seat are pre-lubricated with nigrol.

Washers are placed on both silent blocks; if the old ones are in good condition and not deformed, it is better to install them, since the new ones are of very poor quality, they bend when the nuts are tightened, reducing the service life of the parts. After the nuts are tightened on both sides, the car is lowered from the jacks and needs to be rocked to check how the suspension works. In this case, the creaking and knocking should stop, and the suspension operation should return to normal.

When tightening the silent block nuts, it is better to load the front of the car, first on one side and then on the other, for which you will again need a partner. If it is not there, you can tighten it like that, but then the nuts will need to be tightened again. The nuts are tightened as tightly as possible; if necessary, a pipe is put on the wrench to develop maximum force. At the same time, the threads on low-quality nuts can be stripped. At the end of the work, you need to reinstall the previously removed steering rod.

This method is quite labor-intensive, but does not require special tools such as a puller, or additional knowledge and skills. You can make the replacement yourself in your garage if it has a hole. In this case, you can use a simple tool that every driver has. The quality of work will be in no way inferior to replacement using a specialized puller. The shock absorber silent block and other similar parts are replaced using similar principles. This technique is suitable for VAZ classic series 2101-2107.

Suspension design features

Cars use different types of suspension structures, so the installation locations and the number of silent blocks are different.

For example, classic VAZ models (2101-2107) are equipped with a double-wishbone front suspension, including upper and lower A-arms.

Below is the front suspension of the VAZ 2107.

Each of them has two hinges, on the side where the lever is attached to the car body. But the upper element is secured with a long bolt, and the lower one is mounted on the lever axis, screwed to the body. On the other side, the levers have ball joints.

But in more modern models, starting from the VAZ-2108 and ending with the VAZ-2115, only one lower lever is used.

Below is the front suspension of the VAZ 2109.

There are 2 silent blocks installed in it - at the place of fastening to the body bracket and at the junction of the lever with the spacer.

Another rubber-metal hinge is used on the other side of the spacer, where it is connected either to the mounting bracket (VAZ 2108-21099, VAZ 2113-2115) or to the cross beam (VAZ 2110-2112).

Since the suspension designs are different, the algorithm for replacing silent blocks is different. But in general, this procedure is quite doable in a garage environment, so it is not necessary to contact the service to replace silent blocks.

Replacing the silent blocks of the upper arm

That's all, now you have the upper lever in your hands, you need to knock out the hinges from it. But, of course, you shouldn’t hit it hard, since the rubber reflects the blow, so you can hit yourself in the eye with a hammer if you swing it well. It is best to use a puller for this purpose. If you are repairing a car, then you should have tools available. In particular, a good vice will not be superfluous. Now begins the replacement of the silent blocks of the VAZ-2106 lever, which you have been looking for for so long.

The lever is securely fixed in a vice. You put the puller on the hinge and, screwing in its nut, begin to press out the silent block. Before repairs, it is recommended to treat all components with penetrating lubricant - hinges, threaded connections. And if you don’t want to suffer with the puller, then your only helper is fire. Just warm up the silent block under an open fire. All the rubber burns out, leaving only the metal part of the hinge, which is easily knocked out of the lever with one blow. Of course, this method can be called barbaric, but on the VAZ-2106, silent blocks can be replaced with its help. Especially in cases where the puller fails to remove the hinge.

Silent blocks resource, ways to check them

The service life of silent blocks depends on the operating conditions of the vehicle. If the car is used on roads with good coverage, then the joints can move up to 100 thousand km.

But constant travel on roads with poor road surfaces (potholes, potholes, etc.), of which we have a lot, significantly reduces the service life of the product, and its replacement may be required after 40-50 thousand km.

The main signs of severe wear of rubber-metal joints are deterioration in car handling, vibrations on the steering wheel, knocking from the wheel arches while driving over uneven surfaces.

Checking the condition of silent blocks is not difficult. First, you should simply inspect them, or rather, the visible parts of the rubber elements.

If it is clear that the rubber layer has “come apart” and cracks are visible on it, then such a hinge no longer fully performs its functions.

Additionally, you can use the mount to swing the suspension elements in which the silent blocks are installed. A large amplitude of vibration of the unit and knocking in it indicate critical wear of the hinge and the need for its replacement.

How to replace silent blocks of a VAZ-2106

Quiet blocks Used in the design of cars of all models. They are rubber inserts between parts of the suspension, used to absorb vibrations and, accordingly, to ensure a smooth ride of the chassis. The silent blocks themselves are subjected to very high loads, which leads to their frequent failure.

In this article we will describe in detail how to replace silent blocks on a VAZ-2106; we provide step-by-step annotations and useful tips that will help you perform this complex Do-it-yourself function, without the involvement of car service specialists.

Tools and accessories needed to replace silent blocks

First, you will need to prepare all the necessary tools. Without them, it will be quite difficult to get to the silent blocks in the VAZ- 2106 and dismantle defective parts. So, for high-quality and convenient repairs you will need:

special tools for disassembling ball bearings, front levers, removing and installing a new metal and rubber hinge, as well as for pressing out the remote steering tips;
open-end wrenches, combination wrenches and 13, 22 and 24 mm wrenches;
connector;
fastening kit;
a thin and sharp chisel that allows you to carefully remove the lower silent blocks without removing the lever;
hammer.

Additionally, you will need to prepare the new suspension components for installation on the car. today It is best to purchase polyurethane bushings that are several times different from your normal extended life.

But if your goal. make repairs at minimal cost, then you can make traditional rubber parts.

Step-by-Step Instructions for Replacing Upper Control Arm Quiet Assemblies

If the entire tool is ready for use, we begin to replace the rubber with metal loops, namely:

we lift the car and remove the wheel from the side where the work will be done;
unscrew the nuts holding the silent block and steering tip;
unscrew the mounting nut of the ball joint;
using a special puller, unpack the bipod pin support;
remove the nut that holds the front arm;
remove the lever, carefully clamp it in a vice and change the silent blocks using a special tool;
Install the lever in reverse order. After that, all you have to do is install the wheel and remove the jack. The same work is done on the other side.

Replacing quiet lower control arm blocks is much easier:

Having removed the nut holding the lever itself, take a special tool and press out the rubber-metal hinge;
We are carrying out preparatory work. Along the way, they need to be cleaned of dirt and carefully lubricated the seats for the new silent unit, as well as the axle and threads of the lever. This, firstly, will greatly facilitate further procedures; secondly, this will provide stronger fixation of the part;
click on the new silent block;
install the steering tips and insert the studs that secure these parts;
Tighten the upper and lower arm nuts.

The procedure for replacing silent blocks must be carried out under load. It is best to put your friends or acquaintances in the car in advance, and also put a load weighing 40 kg or more in the trunk.

Tighten the upper and lower arm nuts until the new bushing is installed. Otherwise, serious problems with the car's suspension may occur.

Tools and spare parts

In order to replace silent blocks on a VAZ-2106 car with your own hands, you need a set of appropriate tools. These include:

Set of devices (pullers) for:

removing the upper arm;
dismantling steering tips;
removing and installing hinges.

Jack.
A set of wrenches (socket, open-end, socket).
Chisel.
Mounting blade.
Hammer.
Mount.
Soap solution.

In order to replace worn parts, you need to have on hand:

a set of new silent blocks for VAZ 2101 - VAZ2107 cars;
new fasteners (bolts, nuts, axles, etc.).

Important! It is not recommended to save on the purchase of spare parts in general, and heavily worn ones in particular. The use of high-quality spare parts from well-known manufacturers ensures long-term operation of the vehicle. Recently, experts have advised the use of rubber-metal hinges, the bushings of which are made of polyurethane. You can learn more about their use by watching the video:

A little theory

The silent block is one of the critical parts of the suspension of the VAZ-2106 car, with the help of which fastening elements of such units as:

shock absorbers;
anti-roll bar;
gear box;
jet thrust;
beam supports;
rear suspension rods.

Despite the apparent simplicity of the design, the rubber-metal hinge in the VAZ-2106:

ensures the mobility of suspension parts relative to each other;
withstands axial, radial and angular loads;
absorbs vibrations simultaneously in all planes.

During operation of the VAZ-2106, the silent blocks of the front suspension quickly wear out, which leads to a violation of the geometry of the front wheels and uneven wear of the tire tread. If they are heavily worn, wheel alignment adjustment does not produce results. The only way to get out of this situation is to replace worn out hinges.

The rubber-metal hinges of the rear suspension of the VAZ-2106 wear out in the same way. If the rear axle of the car has lost stability, and a characteristic knocking sound appears in the area of the rear axle when driving on an uneven road, then the rubber-metal hinges of the rear suspension also need to be replaced.

It is best to change pressed, heavily worn silent blocks on a VAZ-2106 car at a service station, whose specialists are equipped with the necessary tools, however, in case of urgent need, you can carry out this procedure yourself.

I want to share my experience of how I change the upper silent blocks

without removing the lever.

Using a jack, remove the wheel where replacement work will be carried out.
Using a twenty-four millimeter wrench, the fastening nut is unscrewed from the lever axis. Now it is advisable to unscrew the nut that holds the steering tip. Afterwards, the disassembly procedure is carried out.
Using a twenty-four millimeter wrench, remove the nut that secures the ball joint.
The puller is used to unpress the bipod support pin (not a big problem if the puller is not at hand, then the lever is simply removed using a pair of thirteen keys).
Next, the nut that secures the axis of the upper arm is unscrewed and pulled out (here the owners of the “six” are lucky, since there is no need to tinker with the bumper mounting bolts like in the “fours”, “fives” and “sevens”).
The lever is transferred to a workbench and clamped between a vice.
Next, using a pre-prepared device, the silent blocks of the upper suspension arm of the VAZ 2106 are completely replaced.
After replacing the rubber-metal hinges, we mount the lever in its place in the reverse order, not forgetting to lubricate the axle before doing this. Oil, lithol, nigrol, etc. can be used as a lubricant. It is important to note that the axle nut does not need to be fully tightened. This process will be carried out under the weight of the vehicle itself.
The support is fixed and the wheel is mounted. The car is removed from the jack.

Procedure for changing silent blocks

the upper suspension arm was carried out completely and successfully.

Why do they fail

Cheap hinges have a short service life. The fact is that rubber has low quality characteristics when used for a long time. It begins to deteriorate, dry out and tear, which leads to the consumable being unusable. In addition, there are other reasons why hinges may wear out and require replacement:

increased vehicle mileage affects the performance properties of rubber in blocks, which leads to damage and deformation of the material;
various reagents and chemical elements that get on the hinge during operation of the machine harm the material. This could be engine oil, substances from the road surface, such as salt or sand, which are sprinkled on roads in winter;
incorrect installation. The arms should only be secured when the vehicle is on the ground and not on a lift or jack. If the fasteners are not tightened correctly, the hinge material will become twisted. This may change its properties and reduce its service life.

Replacement with jet rods

Elements such as torque rods relate to the rear suspension. They are fastened with bolts and bushing-type adapters to absorb impacts, reduce wear and deformation when hitting bumps. Like any other rubber products, such bushings also fail quite often. It is noteworthy that it is recommended to change them all at once.

To disassemble the suspension and torque rods you need a special set of tools:

keys, especially 19 mm;
lubricating fluid;
a set of new hinges;
blade for installation;
brush for working with metal.

The VAZ-2107 car has such an element as a long longitudinal rod. It also has bushings; the process of removal and replacement is also important, because the remaining consumables on other elements are dismantled in a similar way.

In this case you need:

Clean the fasteners from dirt using a special metal brush.
After this, the fasteners must be treated with a lubricating fluid.
After a certain time, unscrew the fastening using a key and remove it.
On the reverse side of the rod, unscrew the fastening of the lower side of the shock absorber.
Remove all fasteners and spacer sleeve.
Move the shock absorber.
Having approached the jet thrust fasteners, lubricate them and unscrew them.
Take a mounting spatula and use it to remove the jet thrust.
The rubber bushings can only be removed if the cage is knocked out of the metal. In this case, you need to apply a special instruction.
You can try to squeeze out or knock out the rubber elements that remain in the traction.
Clean the cage thoroughly before installing new bushings.
Lubricate the new product with liquid and drive or press in with a hammer.
Take a special cone and install a metal sleeve. If it is not available, you can make it yourself by grinding off the head of the bolt.
Press in the bushing with the cone.
To completely remove the bolt, use a sleeve.

How to remove silent blocks without a puller

Without using a puller, most likely it will not be possible to remove the silent block. If you don’t have a ready-made tool, you can make it yourself. There is a sufficient amount of material for this on the Global Network.

Homemade puller diagram

Thus, you can replace the suspension joints in a VAZ-2107 car yourself. This will take quite a lot of time, but will save you on visiting the service. It is advisable to choose a set of new hinges made of polyurethane, as it is more reliable and durable.

What is a silent block

A silent block, or hinge, is a special part of a car’s suspension. Its design consists of two steel bushings, which are connected to each other by a special insert made of soft material. The most commonly used are rubber or polyurethane.

Replacing the lower arm on a VAZ-2107

The hinge connects several components of the chassis, and with the help of a soft insert, it has the ability to dampen various vibrations and thus prevent their transfer to another element. That is, almost all the impacts received by the chassis go directly to the presented components.

The silent blocks take the bulk of the shock from the suspension, which is why they wear out the fastest.

Silent blocks are installed in the car suspension. Available in both the front and rear parts.

The chassis of the car is responsible for handling, dynamics and smoothness. In order for all these indicators to correspond to the factory settings, you need to carefully monitor the condition of the suspension and promptly change the silent blocks, as one of the main components of this part of the machine.

On the front suspension, the arms are attached using silent blocks, and on the rear suspension, the levers are attached to the reaction rods that connect the body and the axle.

Appearance of parts

Types

When a car owner is faced with the question of replacing silent blocks, he needs to carefully select consumables. When visiting a specialized store, the buyer will face a difficult choice between two materials:

Rubber. Made from ordinary rubber. About 70% of all such products are created using this method. These hinges are considered noisier, less reliable and durable, but have an undoubted advantage - low price.
Polyurethane. Products made from this material have a longer service life and high reliability. In addition, experienced car enthusiasts have noticed that their use improves the performance of the car’s chassis. As for the minuses, it is definitely a high price. On average, such silent blocks cost four or five times more than standard ones.

Using polyurethane products on any vehicle will directly improve performance such as ride and handling. In addition, the level of wear of suspension parts will be significantly reduced, since shocks and deformations will be less transmitted and felt by other components.

When replacing the silent blocks of the front control arms on a VAZ-2107, installing polyurethane products will allow you to radically change the behavior of the car on the road and make fewer visits to the service station.
