Changing the silent blocks of the front suspension of a VAZ 2109

From this article we will learn how to change the silent blocks on a VAZ 2109, or rather the lower arm of the front suspension. It can be immediately noted that replacing silent blocks is not a pleasant task and belongs to the category of increased complexity. But if you get used to it and understand how it’s done, then there shouldn’t be any problems.

REPLACING FRONT BUSHING BLOCKS VAZ 2109 , we will need the following tool:

New silent blocks for VAZ 2109.

Soapy water (detergent or liquid soap).

Gas burner or other fire source.

A piece of pipe of such diameter that the silent block fits freely into it.

Chisel and hammer.

It is best to carry out the work on an inspection pit or a lift.

So, let's go. Replacing silent blocks on a VAZ 2109 begins, like any other work, with disassembly and dismantling.

Unscrew the lower arm. To do this, unscrew using a socket with an extension: the extension nut, the nut attaching to the body, as well as the stabilizer link and two ball joint bolts. It will take a lot of effort to remove stuck and rusted nuts; if that doesn’t work, use WD-400 or heat the connection. If the extension nut does not unscrew even after all the methods suggested above, unscrew the crab, then clamp it in a vice and try again.

Next, clamp the removed lever in a vice and, using a lamp or torch, try to burn the old silent block out of the seat. If this method does not suit you, then you will have to press out the silent block using a special puller or the same vice, but using fire it is easier and faster to do this.

After the silent block has burned out a little, remove it with a screwdriver or chisel; it should come out easily.

Now you have a place ready for installing a new silent block, which must be thoroughly blown and cleaned of dirt, dust and rust before installation.

When everything is ready, you can begin replacing the front suspension silent blocks with new ones. To do this, you will need soapy water, thoroughly treat the seat with a soapy solution, then install a new silent block as shown in the photo and lightly, using a screwdriver, begin to press it into the hole. You can also apply undiluted liquid soap directly into the hole, then the resistance will be much less. It may not work out the first time, but don’t rush to despair, look at what is “not letting in” and where, tuck it in using a spatula, add soap and get to work again.

When the silent block goes in halfway, remove the pipe and press everything to the end. Be careful, do not rush, so as not to “bite” the rubber silent block, or install it awry. Don't forget about soap, add more of it.

When you have pushed it to the limit, check whether the silent block protrudes equally on each side. Your result should look something like what is shown in the picture.

Now it's time to replace the silent block of the "daisy" lever. Everything is much simpler here, cut off the old ones using a chisel, and then install the new ones in place. Using the same vice, press them into the mounting hole. Finish with milk and setting.

When the lever is ready, you can begin assembly.

On the other hand, everything is done in the same way.

Choice

Before you start replacing the silent blocks of the rear beam, you need to decide what exactly you will replace the old, worn bushings with.

We figured out the markings and realized that for the VAZ 2109 you need to take only those that are suitable in size and diameter for the rear beam of the nine.

Today, for the VAZ 2109 they offer two types of silents, differing in the material of manufacture.

Silent block type

Peculiarities

They are not as durable, but provide greater softness when operating the car's suspension.

A more rigid modification, in which the increased rigidity is the main disadvantage. At the same time, these products are more resistant to temperature changes, do not deform so quickly, and remain operational longer.

Size difference

Replacing the silent block of the front suspension arm of VAZ 21083

We will replace the silent block of the front suspension arm of a VAZ 21083 (21093, 21099).
Work to replace the silent block will have to be carried out in case of severe wear. Its signs can be considered a knocking sound from the front suspension when starting from a stop and driving over uneven surfaces, and deterioration in the car’s handling when changing lanes.

Necessary tools, accessories and spare parts

Preparatory work

We install the car on a pit or overpass

If there is neither one nor the other, you can simply place the car on a flat surface, jack it up on both sides and remove the wheel.

Disconnect the stabilizer bar link from the suspension arm.

It is most convenient to replace the silent block of the front suspension arm with the arm completely removed. But, below we will describe a replacement method directly on the car. It allows work to be completed in an extremely short time (since there are fewer parts to disconnect) without loss of quality.

Replacing the silent block of the front suspension arm of VAZ 21083 (21093, 21099)

Disconnect the front suspension arm from the bracket

The lever silent block is attached to a bracket on the car body. Using two “19” wrenches, unscrew the fastening nut and knock out the bolt through the mandrel with a hammer.

At this stage, problems may arise with removing the bolt from the bushing of the silent block, since most often it sours there. There are several ways to solve the problem: heating, filling with penetrating liquid and cutting off the bolt with a grinder. We use the one that is most appropriate depending on the situation (degree of souring).

Pressing out the old silent block

The silent block can be pressed out of the lever eye using a puller or a vice with pieces of tubes of suitable diameter.

Pressing in a new silent block

For pressing, we again use a puller or a vice. Before pressing, lubricate the silent block with a soap solution.

After replacing the silent block, we install all the parts back. The final tightening of the bolt and nut securing the silent block is carried out while the car is on its wheels.

Notes and additions

The silent block of the front suspension arm of the VAZ 21083 car consists of a rubber bushing into which a steel tube is pressed. The silent block itself is pressed into the lever head. When the lever swings, elastic deformation of the rubber bushing occurs. Rotation of the silent block bushings relative to each other or relative to the lever head or mounting bolt is considered a malfunction.

How to replace the silent blocks of the rear beam of a VAZ-2109

The service life of VAZ-2109 silent blocks is 30 thousand kilometers. If you prefer to move carelessly - you often fall into potholes or drive over uneven road surfaces at high speed, then the service life of this element can be reduced by almost half. Let's figure out how to replace the silent blocks of the rear beam on a VAZ-2109.

Description of faults and basic information

During vehicle operation, vibrations inevitably appear, which are suppressed by silent blocks. They also prevent deformation. Failure of these parts is accompanied by:

unstable behavior of the car on the road;
uneven tire wear;
squeaks in the rear beam area, impacts on the body (this is especially noticeable on bad roads).

It is worth noting that the described signs are indirect. Loud knocks occur when the rear strut is faulty. In order to accurately determine the cause of the appearance of the described symptoms, it is necessary to diagnose the chassis.

It is necessary to change silent blocks if their design has defects:

decreased elasticity of the rubber part;
breakage of the rubber part;
turning the element in the seat;
bushing displacement.

If you notice that there are problems with the chassis, you should immediately drive the car into the garage, carry out diagnostics, and then subsequently replace it.

It is worth going for repairs even after the silent blocks have exhausted their service life. It’s not difficult to do it yourself.

Purchasing a new item

So, you have found out that problems with the chassis are associated with the breakdown of silent blocks.
Before starting work, you must purchase a new spare part. First of all, look at the labeling. It is important to buy an option specifically for the VAZ-2109. If you make a mistake, it will be impossible to install the silent block. The spare part must be marked: 2109-2914054. Many auto parts sellers may recommend purchasing a spare part from the “ten”, but to install it you will have to work hard to press the rubber part. There are two types of silent blocks:

With rubber bushings. Traditional spare part, provides softness during suspension operation. The main disadvantage is the fragility of such a spare part, especially if you often travel along sections of the road with poor asphalt surface.
With polyurethane inserts. More rigid, which is its main drawback. Moreover, such a spare part lasts much longer, since it is resistant to temperature changes and deformations.

Choose a silent block based on material based on your budget and preferences. Manufacturers BelMag, SEVI, SS20 and Boge have earned good reviews from experts and car enthusiasts.

How is the replacement carried out?

Before starting work, place the car over a hole or drive it onto an overpass. Be sure to secure the wheels with chocks. Next, follow the instructions:

Remove the rear wheel. It will be much easier to work without it.
To replace the silent block you will not need to remove the rear beam, so do not rush to dismantle it.
When working on the left side, you will need to remove the linkage associated with the pressure regulator at the rear of the brake system. To do this, you will need to remove the handbrake cable from the mount located on the right side and the rod fixing bracket.
Using a 12mm wrench, unscrew the nut located on the rear beam mount. Here you may need to create additional leverage using a socket wrench that fits over the knob. After you remove this bolt, jack up the side of the car you are working on.
Carefully push the beam down until it comes out of the eyelet. Watch your actions, as you risk breaking the brake hose.
Prepare a wooden block in advance, which at this stage will need to be placed between the body and the eye. In this case, the beam should be below the eye.
Further work can be done with a special tool, but we will tell you how to dismantle the silent block without a puller. Take a metal tube and a hammer and use them to knock out the old bushings.
Clean the seat.
To make crimping easier, lubricate the seats with soapy water or dishwashing liquid. In this case, it is forbidden to lubricate the seats with oil or grease, since these chemical compounds will corrode the rubber part of the part over time.
Using a hammer or special tool, press the silent blocks into place. Reassemble the vehicle.

Upon completion of work, carefully tighten each silent block support. As you can see, this job is not difficult to do even alone. It takes no more than an hour.

Features of elements

The main function of silents is to eliminate vibrations and deformations that occur during vehicle operation.

When choosing new silent blocks for the rear beam of a VAZ 2109, pay attention to the markings. It should be 2109-2914054. For VAZ 2114-15 models, the markings are different, but the elements themselves are very similar.

In principle, it is possible to install a silent block from a dozen on a VAZ 2109, but you will have to work hard with pressing in the rubber bushing due to the difference in size. The reverse procedure is not possible.

Algorithm for replacing silent blocks of the front suspension of a VAZ 2109

Replacing the silent blocks of the lower arm of the VAZ 2109 front suspension can be classified as complex work related to the chassis. To resolve all difficulties, it will be enough to use a well-established algorithm, which is given below (photos are attached to it).

Required tools:

vice;
new silent blocks VAZ 2109;
liquid soap (can be replaced with detergent or soapy water)
source of fire (a gas burner is suitable);
a piece of pipe whose diameter allows free entry of the silent block;
standard set of keys;
chisel and hammer;
WD-40 penetrating fluid.

To work, place the car on a viewing hole or lift.

To replace the silent blocks of a VAZ 2109, as for other work, disassembly and dismantling are required.

Unscrew the lower lever. To do this, use a socket with an extension to remove the extension nut, as well as the fixation nut to the body. Then remove the stabilizer link and 2 ball joint bolts. To make it easier to work with stuck and rusted nuts, you need to warm up the connection or use a penetrating liquid. If these methods do not help, try unscrewing the crab, clamp it in a vice, and try again.

Secure the removed lever in a vice and use a lamp or torch to burn out the old silent block from its seat. If this option is not possible, you will have to press it out with a special puller or vice, but this will take more time.

After the silent block has burned out slightly, it can be easily removed with a screwdriver or chisel.

Remove dirt, dust and rust from the place where the new silent block will be installed. Blow it out thoroughly.

You can begin installing new front suspension silent blocks. You need to treat the seat with soapy water and press it into the hole with a screwdriver (if you lubricate the hole with undiluted liquid soap, the resistance will also decrease). When everything is ready, you can start replacing the front suspension silent blocks with new ones.

After the silent block enters 50%, remove the tube and press everything to the end. There is no need to rush so that the part is not installed crookedly. You can add soap to make the process easier.

Check the protrusions of the silent block on all sides (should look like in the photo).

Replace the silent block of the "daisy" lever. The old ones need to be cut down with a chisel, and new ones installed in this place. Using a vice, press them into the mounting hole. Finish with a hammer and a pointer.

Reassemble everything in reverse order.
The actions on the other side are similar.
You need to tighten the nuts when the car is already on the ground.

Step-by-step instructions on how to change rear silent blocks on a VAZ 2109

Are you starting to repair your car yourself? Then objectively evaluate your strength, knowledge, and degree of patience. You will be faced with a complex multi-component system, where it will be necessary to take into account the condition of each part in order to replace the faulty one and figure out, for example, how to change the rear silent blocks on a VAZ 2109 and what is important to do at one stage or another.

The first stage of replacing rear silent blocks on a VAZ 2109: collecting information

Armed with the necessary data, you will be able to perform all the simple dismantling and installation work, determine the degree of malfunction of the part and ways to eliminate it. If you need to check or even replace the silent block on the rear suspension of a VAZ 2109, then you need to figure out, first of all, what kind of part it is.

Firstly, the silent block of the rear suspension of the VAZ 2109 is a small part, which is composed of several bushings of different diameters, and an elastomer is introduced between them, that is, a special wear-resistant rubber or polyurethane. Secondly, the main task of the silent block is to connect the necessary suspension arms and help it function efficiently, and in certain situations while driving, dampen vibrations, preventing discomfort in the car interior. After all, it’s always good when bumps in the road are not strongly felt by the driver and passengers of the car, and all thanks to the silent block, as a suspension element, which is designed to dampen cardan shafts, torsion bars, and all kinds of axial vibrations.

Symptoms of a problem

There are several main signs of failure of the rear beam silent blocks, including:

Unstable behavior of the car on the roads;
Tires wear unevenly, which is not difficult to notice from the tread pattern;
When driving on a bad road (that is, 95% of all our roads), unpleasant squeaks and impacts on the car body are observed.

These signs are indirect, since they may be associated with other failures of the vehicle’s chassis. For example, dull knocks are also a sign of a faulty rear pillar. Therefore, in order to make sure that there is a particular problem, you will need to fully diagnose the chassis.
