Notes:

Remove the lever from the car to replace it or replace the silent blocks of the lever. The work to remove the left and right front suspension arms is similar. Carry out the work on an inspection ditch or overpass.

Removing the front suspension arm

1. Disconnect the ball joint from the control arm as described in this article.

2. Unscrew the nut securing the brace to the front suspension arm and remove the washer as described here.

3. Unscrew the nut of the bolt securing the stabilizer bar to the arm and remove the bolt as described in this article.

4. Using two 19 mm spanners, unscrew the nut of the bolt securing the lever to the body.

5. Using a soft metal drift, knock out and remove the bolt, then move the lever out of the bracket and remove it.

Replacing the silent block of the front suspension arm

1. Place the lever from the silent block in a vice and, using attachments, press it out of the suspension arm.

2. Before pressing in, moisten the new silent block with soapy water.

3. Knock down the silent block of the extension with a chisel on both sides of the lever.

4. Pre-press new silent blocks in a vice and finally press them by striking a punch with a diameter of 8 mm through three windows in the rubber layer.

5. Install the lever in reverse order. Tighten the threaded connections of rubber-metal hinges after removing the jack or ditch lift.

You can recognize problems in the front suspension system, and more specifically the silent blocks on the Lada Kalina, by the characteristic sounds it makes while driving. Thus, driving on an uneven road may be accompanied by various cracks, squeaks and other unpleasant noises. This situation not only causes great discomfort, but can also cause a more serious malfunction or cause an accident.

Replacing silent blocks on Kalina

Front suspension silent block close up

The silent blocks on the Lada Kalina car are located exactly the same as in the VAZs of previous years. These elements are located generally on or adjacent to the wishbone . You will have to change them either on the entire element at once, or by selecting the most damaged ones. Of course, if there is damage on one of them, the wishbone with rubber (stock – approx.) stabilizers must be removed and replaced with polyurethane analogues.

Removing the wishbone

1. In order to begin work on replacing old silent blocks with new ones, you need to place the car on a viewing hole, a lift, or jack it up.
2. Next, you need to remove the wheel and spray all the connections on the wishbone with WD-40.
3. After the lubricant has penetrated into all hard-to-reach places, we begin to unscrew the bolts.
4. First of all, we begin to dismantle the ball joint bolt, but before that we remove the cotter pin from the bolt.
5. Then we unscrew the bolt securing the longitudinal tension hinge (where the “daisies” are attached - approx.) and remove it from the seat.

A generously lubricated bolt is a guarantee of success.

When dismantling this unit, there should be no problems.

For the best impact on the bolt, you can use a wrench extension.

Rubber-metal longitudinal tension joint

The rubber-metal longitudinal tension joint, or popularly simply “daisy”, is designed to take the brunt of the impact from uneven road surfaces; despite the fact that this element is very important, it is very easy to dismantle.

Having previously clamped the lever in a vice, we knock out the silent blocks one by one using a chisel or a thin flat screwdriver.

Punching out “daisies” is not an easy task.

This is what the old suspension elements look like

To cause the least damage to silent blocks, it is better to place pieces of wood between the vices.

Stabilizer strut and cushion

1. The stabilizer bar, or simply “eggs,” and the cushion provide the stabilizer bar with stable operation while driving the car.
2. It is very easy to dismantle the “eggs”, just unscrew the mounting bolt from the transverse arm, and simply release the other end from the anti-roll bar by simple rocking.

Sometimes it happens that they just break

After unscrewing the fastening, it is very easy to remove the pillow, but putting on a new one is much more difficult.

Cross Arm Bracket

1. The largest silent block of the lever located at the very base, despite the fact that it has, among others, more impressive dimensions, is not difficult to dismantle.
2. The easiest option to remove it is to set it on fire. When the rubber on it burns out, you just have to take it out and clean the seat. (Of course, you can press it out through a vice, but this will take time and may cause some inconvenience).

We install new silent blocks

Now the moment has come when you can install new silent blocks on the Lada Granta, the main thing is to know how to press them in. The landing site will need to be pre-lubricated, you can use graphite lubricant, then the nut is screwed on, the silent blocks of the grant are pressed in, the price for them is not high. In this case, you can do without special devices that allow you to press parts. And you don’t need to remove the lever itself, as some people do.

When you have figured out how to change the silent blocks on the grant, it is worth remembering that after replacing you need to loosen the nut so that you can attach the crab. It must be taken into account that the holes intended for fastening are displaced. So Lada Granta, replacing silent blocks is not complete without a hammer, which is useful for adjusting the holes. It will be necessary to use it on both sides.

After replacing the silent blocks on the grant is completed, you may encounter an amazing effect. Drivers notice that the roughness in steering disappears, the steering wheel becomes more obedient, and the road holds without problems. Therefore, if there is a suspicion that the silent blocks of the front levers of the grant have become unusable, it is better to immediately look for the cause and replace them. As a result, you will receive a machine whose performance will only please you.

Important!

If during the work you find that the bolts and nuts are in poor condition (there are cracks, traces of severe rust, bad threads - approx.), then it is best to replace such elements with new ones, using high-quality steel bolts and nuts with a self-locking element .

Other front suspension elements

The remaining elements of the front suspension, which contain rubber-metal and metal hinges, are replaced immediately as an assembly. These include:

• Spherical bearing.
• Stretch bracket.
• Steering end.

These elements cost about 500 rubles per set, and also do not require specific installation skills.

What to do about the knocking?

If you do not pay attention to the problem and do not change the silent blocks on the grant, the knocking will become increasingly stronger. Therefore, it’s time to drive the car into the pit, remove the engine protection, and look at all the details. You can swing the car from the desired side, whether you hear a knock or not, but it will happen if the silent block on the grant has become completely unusable. If the problem is in the stretcher, then you need to pull it too, the resulting knock will be proof that the cause of the breakdown has been found.

You can replace the silent blocks with grants, the price of which seems reasonable, right in the pit, without the need to remove the levers.

Tools required:

1. 2 keys for 24. 2. Extension tubes. 3. Head 17. 4. Thin screwdriver. 5. Punch, it is better to give preference to the canonical one. 6. A hammer, it will hardly be possible to do without it in work when the silent blocks of the grant need to be replaced.

Causes of knocking in the front suspension

In total, there are four main reasons why noises and squeaks can annoy the Lada Kalina car owner, and three of them can be eliminated independently and everything can be returned to a safe state.

1. The first reason why knocking occurs in the suspension is the poor quality of the road surface . A suspension that is in good working order can also produce some extraneous noise. If the noise disappears when you drive onto a good road, then everything is fine with your suspension, you can move on to the point below.
2. If knocking and simultaneous vibration occur in the steering wheel, the reason may lie in a faulty steering rack . If you can tighten the steering rack yourself, then it is better to entrust its repair or replacement to professionals.
3. The third reason is the front suspension strut spring that has lost its elasticity . Since the spring tone is significantly reduced, the suspension hits directly against the body. How to change the front struts, and along with it the spring, is described in detail in this article.
4. And the last reason is cracked silent blocks, which are simply necessary to thoroughly dampen knocks and vibrations that occur while driving. Read below for information on how to properly replace these front suspension elements.

If you are going to drive a car in winter, it would be a good idea to check the condition of the chassis and transmission so that you do not have to do repairs right on the road, in dirty snow slush. Any Granta owner can save both time and money if they check the car themselves. Today we are talking about the chassis and transmission.

Location and duration of operation

Not knowing where the silent blocks are

in a car, you can easily miss the moment of their failure, which can be fraught with a variety of consequences. In most car models, silent blocks are located:

1. in places where shock absorbers are attached;
2. in places where jet rods are attached;
3. at the attachment points of the transverse stabilizer;
4. on the supports of the beams to which the gearbox and motor are attached;
5. on the rear suspension bars.

In general, modern rubber-metal joints can be actively used for up to 200 thousand kilometers, although given the disgusting quality of roads, this value often has to be divided by four. It doesn’t matter what silent blocks are installed on the car - they need to be inspected approximately every 50,000

kilometers run.

A silent lock that has become unusable can be clearly identified visually: cracks and tears are visible on it.

We make sure there is no play (knock). If there is a knock on the front wheel, ask an assistant to press the brake pedal. If the knocking noise disappears, it means the wheel bearing is faulty, and if the knocking noise remains, then the ball joint is most likely worn out.

The hub bearings of the front and rear wheels are not adjustable and must be replaced if there is play.

To check the serviceability of the ball joint, insert a mounting blade between the suspension arm and the ball joint housing. Be careful not to damage the ball joint boot.

Detection of silent block faults

You can check the silent blocks for functionality yourself. In addition to the visual identification of failure, there are also general symptoms indicating a high probability of failure of one or more silent blocks. When suspension silent blocks fail, the following problems are observed:

• the quality of the car’s stability on the road deteriorates, it begins to “drive” from side to side;
• noise and vibration increases when moving;
• A characteristic increase in tire wear begins to appear when the sides of the wheels wear more actively.

If these or other symptoms appear, the silent blocks should be diagnosed. To do this, the suspensions are hung with a jack and the wheels are removed. This will allow you to visually assess the current state of the hinges, and will also make it possible to check the play of the levers.

Complete wear of silent blocks, in addition to accelerated wear of the wheels and reduced ride comfort, is fraught with more global problems. For example, the metal parts of the hinges break down the seats over time, which is why when repairing the chassis you will have to worry about replacing not only the silent blocks, but also a number of other parts, since such problems are most often not eliminated by restoration.

To change the silent block you will need a special device or a set of spacers of the appropriate diameter.

The suspension springs must not be damaged. Tearing, cracking and severe deformation of rubber bushings, cushions and compression buffers of shock absorbers are unacceptable.

Liquid leakage from shock absorbers is not allowed. A slight “fogging” of the shock absorber in its upper part, while maintaining the characteristics, is not a malfunction.

If the rubber element of the upper support of the front suspension telescopic strut settles or is destroyed, the support must be replaced.

Why are “quiet” bushings needed?

A silent block is a rubber-metal cylinder-sleeve that is used to connect suspension elements, as well as for fastening gearboxes and engines.

Due to the fact that it contains elastic material (rubber or polyurethane), it dampens vibrations, shocks and vibrations.

If it were not for silent blocks, then driving a car would turn into hell - we would be shaking, body parts would quickly break, not to mention the noise that would be created by the joints of metal structures with the car body.

In truth, these rubber-metal parts are durable and last up to 100 thousand kilometers, or even more, but different things can happen - defects, negligence of assemblers, or the influence of aggressive environmental factors.

In a word, sooner or later the moment comes when it is necessary to replace the silent blocks.

Lada Granta suspension diagnostics

To identify and eliminate the cause of the rattling, I decided to inspect the entire suspension of the Lada Grant for the presence of play and “tired” elements (bushings, rubber bands, etc.), since I thought that the problem lay somewhere there. So, let's begin.

Checking the front struts

The first thing I did was check the front struts. While rocking the car from side to side, I simultaneously kept one hand on one of the racks. If the knocks were coming from the front shock absorbers, I would have felt them. However, there were no knocks.

Benefits and price

Based on just these two tables, it would seem that one can make a bold conclusion that polyurethane is clearly ahead of rubber, if you do not take into account its triple cost in relation to the same ITP 1357 rubber. For example, a set of polyurethane silent blocks for a classic VAZ for a stabilizer lateral stability costs at least a thousand rubles, and for mounting the front suspension arms for the Niva, the price of the kit will be from 1,400 rubles. That is, it’s a little expensive.

But here, not everything is so simple, since polyurethane, a two-component elastomer, has a number of advantages over rubber:

1. High degree of resistance to mechanical loads.
2. Resistance to aggressive liquids and gases, of which there is plenty in the car.
3. Resistance to high and low temperatures, and polyurethane does not change its characteristics from -45 to +85 degrees, which cannot be said about rubber.
4. This leads to a long service life of bushings, silent blocks and bump stops made of polyurethane, almost three times longer than the service life of rubber.
5. Resistance to deformation within certain limits, resistance to abrasion.

Additional recommendations for replacing the ball joint

There are special stock Lada Granta ball joints for sale for sporty driving. They have increased strength. Many car owners recommend installing them. According to reviews, the service life of tuned supports is 20-30% longer than original ones.

The service life of the ball joint is directly proportional to the quality and quantity of lubricant under the boot. Therefore, it is recommended to remove the cuff and check the contents before installation. For fear of tearing the boot, car owners apply additional lubricant using a syringe, bending the rubber band on one side.

You can dismantle the ball joint without a puller. To do this, you will need to remove the lever with accompanying elements in the assembly.

If you do not have special tools, you can remove the support from the lever by knocking it out with a hammer. Strikes should be applied sharply and accurately. With this method of dismantling, the risk of damage to the lever and ball seat increases significantly. For this reason, experienced drivers still recommend purchasing a puller, the cost of which is from 500 to 1400 rubles.

Rear suspension

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.

Why do silent blocks fail and how often do they need to be replaced?

The malfunction is due to natural wear and tear of the materials. The working life of silent blocks ranges from 50 to 150 thousand km . mileage, so it is impossible to give clear recommendations on the frequency of their replacement. We only advise checking their condition at every opportunity - a visual inspection takes less than a minute.

The worse the operating conditions, the shorter the working life of the parts. If you often drive on bad roads and load your car to capacity, then the silent blocks will wear out faster.

What is a puller for installing silent blocks?

This is what a RMSH puller looks like, which you can make yourself. In order to make it yourself, at home, you will need the following materials and tools:

• Bolt with nut. The diameter and pitch of the thread are at your discretion. If the thread is small, you will have to turn it longer, but it will work easier and smoother.
• We select a cylinder with a diameter such that the silent block fits into it.
• Washers. Some. One washer should tightly cover the cylinder hole. You can even weld the washer on one side. We take the remaining washers with a smaller diameter than the diameter of the silent block.

What is a silent block of a suspension arm and its functions

In car structures where there are vibrations, displacements, radial and axial loads, there must be softening special rubber parts. They perform an important function, so they need to be changed frequently. Rubber parts that are subjected to compression, tension, and displacement wear out quickly. A silent block is a rubber-to-metal joint (RMH) in the design of a car suspension. The salent block device includes:

• two metal tubes;
• rubber connection between these tubes.

This part is made by vulcanization, which is why it has excellent vibration insulation properties. Salent blocks are capable of absorbing all types of loads that appear during vehicle operation.

If the silent blocks are heavily worn, then driving the car will be uncomfortable, noise will appear and the joints of the parts will begin to wear out faster.

Silent blocks are installed on the front and rear suspensions. They are installed on levers. In addition to levers, silent blocks connect the mounting points of the gearbox, engines and shock absorbers.
