Each individual VAZ 2110 engine mounting mount and all of them together are designed to provide reliable mounting while simultaneously vibration isolating the engine and gearbox on the vehicle.
Therefore, if, while driving over bumps, when changing gears or during other actions, you begin to feel vibrations and characteristic tapping and creaking in the engine area, as if the pieces of iron are hitting each other, indeed, it is the motor mounts that should be suspected.
Engine support cushion
On the VAZ 2110, the cushion is a rubber-metal part such as a silent block. On one side this part is attached to the body, on the other - to the engine cylinder block. They hold not only the engine, but also the gearbox.
This design has proven itself well - it is reliable and not expensive. But - as long as the pillows are not destroyed.
Design difference
On a VAZ 2110, the engine is usually held by three or four points at the bottom, and two or three at the top. But you should know that the 8 valve engine has a rear engine mount. The 16 valve does not have it, but it has additional supports.
Self-adjustment of VAZ 2110 valves is discussed here:
Rear support cushion for 8-valve engine
But in general, their replacement is similar.
By the way, if desired, additional support can also be installed.
Useful tips
Please note that when engine vibrations occur, you should not always immediately change all the supports “in a circle”. It happens that even on a relatively “fresh” car, only one element fails, while others are quite suitable for further use. This occurs as a result of technical fluids getting into contact with the rubber part of the cushion, etc.
However, as for basic recommendations, if the car has a mileage of about 80-100 thousand km. and more, and all engine mounts have the same service life and have begun to fail, it is better to immediately replace all such mounts.
The reason is obvious - if the rubber begins to deteriorate from old age, after replacing one clearly faulty element, after a while the next cushion will also no longer cope with its task.
We also recommend reading the article on how to check the ignition module of a VAZ 2110. From this article you will learn what signs indicate that the ignition module is malfunctioning, as well as how to diagnose the ignition module 2110.
It is also important to select only original products or high-quality analogues for replacement, as well as purchase parts from trusted sellers. The fact is that there are a large number of spare parts on the market for VAZ cars, but not all of them are of high quality. Moreover, you often come across cheap fakes of an original of unknown origin.
Functionality check
Before changing pillows, you should check the functionality of the old ones. It may happen that the cause of vibration and knocking is not in them.
You can learn about the influence of the crankshaft sensor on engine operation in this material:
So:
- We put the VAZ 2110 on supports;
- We install a jack with a backing made of board or timber under the oil pan and jack up the engine until the cushions are freed from its weight;
- We check all the pillows, namely: • Are there any cracks on them; • How easy it is to separate them from the substrate (it is made of metal); • Are they still hard? • If no obvious deficiencies are found, and replacement is not yet necessary, check the play between the frame and the plates; • Lubricate the cushions with a protective compound, lower the motor, tighten the fasteners and nuts.
When and why you need to replace engine mounts: what to look for
First of all, it should be noted that the engine has several mounts: the right engine mount, the top engine mount and the rear mount. The support itself is a rubber-metal part, consisting of a metal body and a rubber insert (cushion).
To put it simply, the pillow vaguely resembles a silent block in design. The main objective of this solution is to dampen vibrations during operation of the internal combustion engine. Also, the absence of rigid fastening of the power unit to the body makes it possible to increase the service life of some body elements.
For example, when driving over uneven surfaces, the engine “rocks” on rubber cushions, the support smoothes out the vibrations, and there is less load at the mounting points of the internal combustion engine. If we talk about the VAZ 2110 model, the 8-valve engines on this car are secured using three supports (two side engine mounts, as well as a rear cushion). In turn, the 16-valve engine has 4 airbags (two side pores, a lower front airbag and an upper front airbag).
- To determine when engine mounts need to be replaced, it is enough to assess the level of vibrations during engine operation. As a rule, if the engine mounts are faulty, strong vibrations will be transmitted to the body. Moreover, vibrations will be clearly felt on the steering wheel, pedal assembly, gear knob, etc. In such a situation, the entire body usually “shakes”, and the cause is faulty power unit mounts.
Engine vibration is felt most strongly during startup and also when the engine stops. Also, especially when the cushions are critically worn, a knocking sound may occur when the engine comes into contact with the support.
- To determine the condition and need to replace the engine mounts, it is often enough to start the engine and then inspect the mounts and mounts. You also need to pay attention to the strength of engine vibrations at idle by placing a hand on the valve cover.
In practice, if deformation of the cushions is noticeable, the rubber has cracked/delaminated and lost its elasticity, in this case it is time to change the engine mounts. You can also perform additional verification. To do this, you need to know how to check engine mounts. In short, you need to “rock” the engine in the car with jerks in first or reverse gear, and at this moment an assistant controls how the engine shifts at this moment.
Having discovered that repairs are necessary, you should not delay replacement, since vibration actively destroys the body, internal combustion engine, gearbox, attachments, etc. It is also important to understand before starting work whether the entire mount will be replaced or just the mounts, since in the case of the VAZ 2110 and a number of other models it is possible to replace the engine mounts or mounts.
By the way, experts recommend changing the entire support. On the one hand, it is more expensive (if only the VAZ engine mount is changed, the price will be lower), but you can count on better results if you buy a good quality engine mount assembly.
8 valve engine
If you need a replacement on an 8-valve valve, then proceed as follows:
- Right pillow. It is necessary to unscrew: • The upper nut; • Bolts for fastening to the bracket; • Bolts under the wheel arch securing the bracket to the side member. We remove the bracket and install a new pillow, reassembling it in the reverse order.
- Left. After unscrewing the top nut, lower the motor onto the prepared support and pull out the top washer from the support. We unscrew the fastening bolts, remove the washer, after which you can replace it;
- Rear (8-valve only). Unscrew the nuts that secure the airbag to the body, then the bolts securing it to the gearbox. The new part may come with a bracket. But if it is not there, install it with the removed one and assemble all the parts in place.
Replacement
The replacement procedure should not cause much difficulty for those who have independently repaired their car more than once, especially the suspension and chassis.
If you have no experience, then we recommend contacting a service station. Only proven and reliable.
Dismantling works
Replacement has its own nuances depending on the pillows for each engine in question. We will separately talk about the repair of 8 and 16 valve engines.
8 valve engines
- Select a flat surface for repairs, place chocks under the rear wheels, and turn on the handles.
- Remove the engine protection.
- Unscrew the bolts of the generator belt tensioner, after which this belt must be removed. You will need a 13mm wrench.
- Place a jack under the car, place a strong wooden board on top and lift the engine until it releases the load from the supports.
- Using a 15 wrench, unscrew the central fastening nut of the worn pillow.
- Now use a 13mm wrench to unscrew the airbag fixing bolts mounted on the bracket.
- From below, near the right arch, 3 more bolts are unscrewed. They are responsible for connecting the bracket to the spar. You need a 17mm wrench.
- The bracket is removed, the pillow is removed and replaced with a new one.
- Next, perform assembly in reverse order.
- Place the jack under the transmission and then lift it up.
- Using a 15 wrench, unscrew the nut of the central fastening of the left pillow.
- Using a 13mm wrench, unscrew a pair of bolts securing the support, after which it is removed.
- Replace the damaged element, and then carry out the reassembly procedure.
- Remove a pair of nuts with a 17mm wrench. They secure the cushion to the body. Then a couple more nuts connecting the cushion to the gearbox are unscrewed.
- Remove the rear support.
- Using a 17mm wrench, remove the fastening nut connecting the bracket to the cushion. A new rubber part is installed in place of the old element.
- The rear support is returned to its original state by reassembly.
16 valve engine
If you have a 16 valve engine under the hood, then there are some nuances for replacement.
On 8 and 16 valve engines, dismantling and replacing the side cushions is carried out in a similar manner, there is no difference. But the front lower ones change differently.
To change the front lower mount on a 16 valve engine, you need:
- Unscrew the front lower support rod fixing bolts in relation to the front suspension cross member. For these purposes, arm yourself with a 15 key;
- Unscrew the fastening nut that holds the support to the engine bracket. You will need a pair of keys at once and both are 15. The bolt is removed;
- Remove the support, change the cushion on it or replace the entire assembly;
- Reassemble;
- In the engine compartment, unscrew the fastening bolt of the upper front support to the car body, while holding its nut by hand. This is where the key for 17 comes in handy;
- Remove the bolt and nut;
- Remove the fastening bolt of the front upper support in relation to the power unit bracket using 15mm wrenches. The bolt and nut are removed;
- The support can now be removed, the pillow or the entire assembly can be replaced;
- Assembly is performed in reverse order.
Assembly of the unit
Additional support
To make movements in the longitudinal direction smaller, you can install an additional support. It is also called a suspension bar. Mostly they can be found in online stores.
Additional support
To mount an additional support on the 8-valve power unit installed under the hood of your VAZ 2110, you will need to purchase a special bracket used to transfer the ignition module.
Reviews from those who have performed such operations claim that when starting off the car does not jerk, the engine does not become loose, which has a positive effect on the wear of the cushions.
An important useful property of modification by installing an additional support is to prevent the lower pipe from falling off the radiator, which seriously affects dozens of people.
There are a lot of opinions regarding reducing vibrations. Some consider this a useless exercise, while others, on the contrary, note significant improvements in the behavior of the car.
Prevention measures
To prevent breakdowns, it is best to carry out periodic maintenance. This way you will spend much less effort and time on repairs.
Preventive measures include:
- Periodic check of bolt tightness;
- Removing dirt and oil traces from the rubber elements of the engine mounts with a dry rag;
- Regular repetition of these activities every 4 months.
In practice, even a relative beginner in the field of do-it-yourself repairs takes no more than 5 hours to replace engine mounts. But this allows you to develop your own skills, as well as save a decent amount of money on the services of service stations.
Let's sum it up
Taking into account the above information, it becomes clear that replacing the engine mounts/mounts of the VAZ 2110 and a number of other models is not a complicated procedure. However, before carrying out work, you need to accurately determine the need for replacement itself, as well as which pillows need to be changed.
We also recommend reading the article on how to replace the VAZ 2110 clutch with your own hands. From this article you will learn about the signs that a clutch needs to be replaced, as well as how to change the clutch on a 2110 yourself in a regular garage.
Finally, we note that operating a car with faulty engine mounts affects not only comfort, but also the service life of the car’s components, as well as the body. For this reason, if the engine vibrates strongly, this is a reason to check the supports and completely/partially replace the power unit support pads.
Additional support
In order to reduce engine movement in the longitudinal direction, an additional support (suspension rod) can be installed. They are mainly purchased in online stores. An additional support is installed on all types of VAZ 2110, but it has its own characteristics.
For an 8-valve model, you also need a special bracket that is used to carry the ignition module. Those who installed such a bar claim that when the car starts moving, the engine does not wobble, the cushions do not wear out as much, and the lower hose does not come off the radiator (which is what dozens of people “suffer from”).
Opinions differ regarding the decrease/increase in vibrations.

When should you change the power unit mounts on a VAZ 2110: signs and reasons
Before you change the engine mounts of a VAZ 2110 car and watch a video of this process, you need to study the signs that indicate a breakdown of the rubber-metal mounts. The main symptoms characterizing problems with damper units:
- Vibrations transmitted to the steering wheel and pedal unit when idling.
- Extraneous noise in the cabin when moving on an uneven surface.
- A characteristic knocking sound in the engine compartment during acceleration and braking.
When drawing conclusions after your observations, you should not confuse vibrations on the steering wheel during braking, which are associated with defects in the brake discs or pads. To be more convincing, you need to open the hood and inspect the power unit supports. If you place your palm on a running internal combustion engine, you can feel changes in its operation.
Many years of experience in operating the Lada 2110 allows us to assert that the reasons for the failure of damper cushions are the following factors:
- Deformation phenomena on the rubber support due to mechanical and temperature influences, as well as due to exhausted service life.
- Cracking and delamination of rubber from exposure to chemically active components.
- Loss of elasticity caused by temperature changes.
Premature failure of the damper support can be caused by the owner’s excessive enthusiasm for such extreme techniques as sudden starts and emergency braking. Suspension parts are already subject to serious stress while driving, and a sporty driving style further increases the risk of their failure.
Do-it-yourself repairs and preparatory work
Replacing the VAZ 2110 gearbox cushion
The knocking starts when the gear is switched from 1 to 2 or from 3 to 4. The knocking also occurs when driving on country roads at one speed. One thought immediately arises: the checkpoint is buzzing. What to do? Contact a car service center or look for the cause yourself. A car enthusiast, not a specialist, needs to know a simple truth. At service stations, minor repairs are taken on reluctantly or even refused due to workload. They may, of course, offer to repair the gearbox. Since such repairs will bring financial profit. But the result is the same. The knock under the bottom will remain. Therefore, there is no need to despair. You need to visit a car store and buy the necessary spare parts:
- 2 assembled pillows (choose from the Volzhsky Rubber Plant or Balakovo);
- 2 bolts M12x75; 4 washers dia. 12 mm;
- 2 nuts - 12 mm with nylon insert;
- 2 bolts M10x25; 6 wide washers - 10 mm;
- 2 engraving washers - 10 mm;
- 1 VAZ-2108 timing case bushing.
What is needed for repairs
First, you need to determine which support on the VAZ 2110 engine should be changed (if you do not want to change all the damper mounts at once). To do this, you need to do an independent inspection of these parts. Sometimes, the power plant seems to be tilted horizontally on one side or tilted along the central axis of the car. This is the first sign to replace the damper mounts.

Two cushions (side) secure the engine to the left and right side members in the engine compartment. And one (rear) fixes the motor to the bottom. Therefore, it is necessary to lift the machine on a lift or install it on a viewing hole. The wear is immediately visible. The rubber has tears and core failure. Depending on the result of visual diagnostics, you should purchase the required number of parts for installation.
You will need a tool. In most cases, a standard locksmith set consisting of open-end and box-end wrenches with heads will be sufficient. In addition, to replace engine mounts on a VAZ 2110 you will need a rolling jack and a pair of short boards. It is advisable to have electricity and a cutting machine with a disc, since you may have to cut off the mounting bolts.
Helpful information! A couple of hours before repairs, it is strongly recommended to apply universal lubricant “Liquid Key” to the threaded connections. Damper supports are changed very rarely, therefore, unscrewing them without prior preparation is quite difficult.
Testing
After carrying out the replacement work, it is important to check the result.
To do this, start the engine and check the vibration level. With low vibration and quiet operation, removal and replacement were done correctly. If not, it means the fastenings are not firmly fixed enough. You need to check the installation of the supports again and possibly secure them. Obviously, if there are excessive vibrations when the engine is running, it is worth checking the engine mounts and the condition of the rubber on the mounts. Timely replacement will at least restore the level of comfort in the cabin.
