VAZ 2110 is a car that is equipped with a gasoline power plant and a manual transmission (5 steps). This version of the box is reliable and easy to maintain. To extend its service life, you need to use original transmission oils, and during repairs, use high-quality and reliable components. Particular attention in the transmission system should be paid to such an element as the gearbox mounting pad.
Types of gearbox cushions
The existing gearbox on the VAZ 2110 is equipped with reliable spare parts, the interaction of which ensures smooth operation of the vehicle. It should be noted that it is maintainable. One of the elements of the transmission is gearbox cushions. These components can be of the following types:
In terms of price, the rubber-metal option is cheaper. As a rule, it is most often found on the 2110 model. The rubber can be made of polyurethane. This material is characterized by increased wear resistance and has good shock-absorbing properties.
Hydraulic options cope well with the loads placed on them and are able to effectively dampen vibrations that occur when movement occurs. The design of the present support is a housing that has two chambers with a special filler, between which there is a membrane.
Problems with box supports are rare. Long-term operation of the vehicle over rough terrain and temperature changes help reduce its service life. Because of this, the rubber of the cushions loses its elasticity and breaks down. As a result, there is a need for repair and restoration work.
Installation of an additional lower gearbox (engine) support for Lada Priora
Lada Priora is a modernized version of the VAZ 2110; the design of these cars has many of the same parts, for example, doors or body parts. This allows you to adopt some improvements from the “ten”, one of which is the installation of an additional gearbox cushion.
On 8 valve engines the factory installed a rear gearbox mount, but on 16 valve engines they have already abandoned it. As practice and reviews from VAZ 2110 owners show, installing an additional gearbox support is a useful modification that can make the operation of the car more comfortable.
On Priors with 16 valve engines, the rear gearbox mount is also missing, but the attachment points to the body remain.
Troubleshooting airbags
The metal base of the cushion provides good mechanical support for the gearbox. Thanks to her, this unit is securely fixed in its normal place. The gearbox support 2110 has good resistance to external loads, as well as temperature changes. The service life of this component depends on the operating conditions of the vehicle. The ingress of dirt, sand, etc. flying from the roadway helps to reduce their service life.
You need to pay attention to the condition of the pillows if the following manifestations are noted:
- vibrations at the beginning of the trip;
- extraneous knocking noises when braking;
- hum
In addition to this, it can knock out speed. Among the reasons for these manifestations may be deformation of the pillow as a result of strong temperature exposure. Also, the life of the gearbox cushion is negatively affected if oil or antifreeze gets on it.
Important! The presence of knocks and extraneous noise from the VAZ 2110 high-speed gearbox is not always due to the fact that the airbags have become unusable. These manifestations may be the result of broken gear teeth or loose threaded connections. Taking this into account, vehicles are subject to full professional diagnostics.
Thus, if the faulty consumables on the VAZ 2110 are not replaced in time, then the motorist may soon experience engine and gearbox breakdowns. As a result, vehicle control will deteriorate and there will be a need for serious repairs.

In today's article we will talk about such important elements of the transmission as gearbox mounts. Many car enthusiasts do not even know what they look like or where they are until these products make themselves felt with various types of malfunctions.
In order to understand and promptly respond to emerging problems with gearbox mounts and resolve the issue with minimal means, we will try to talk about their purpose and malfunctions in more detail.
Purpose
The gearbox supports are designed to secure it to body elements, as well as to suppress vibration and noise when driving.
Device and types
Depending on the design of the vehicle, gearbox supports can be made in different designs. Depending on the type of cushion, the boxes can be rubber-metal or hydraulic.
Rubber-metal
This type of product is a simple design consisting of two metal plates between which there is wear-resistant rubber.
This is the cheapest and most popular type of pillow. Recently, some manufacturers have begun to replace rubber with polyurethane due to its increased wear resistance. This type of support is available in both collapsible and non-dismountable versions.
Hydraulic
These cushions are a more modern design and are able to effectively smooth out any vibrations, adjusting to the operation of the power plant.
The support itself is a housing with two chambers located in it, with a membrane between them. Both chambers contain a hydraulic filler. The purpose of the membrane is to eliminate slight vibration when the car is not moving quickly on a flat highway and the engine is idling.
The liquid in the chambers is responsible for the vibrations that appear at speed. The changing pressure forces it to move between the chambers of the support, increasing the stiffness of the cushion, while dampening almost any strong vibrations.
Basic faults
On average, the service life of gearbox supports is about 100 thousand kilometers or more. However, during long-term operation of the vehicle, the power unit supports experience various loads, plus temperature changes, which negatively affects their condition. The rubber of the cushions loses its elasticity, delaminates, or cracks, and eventually completely collapses.
Large loads on the gearbox supports occur when starting and braking the vehicle. At the same time, if the driver prefers an aggressive driving style, that is, he starts abruptly and brakes sharply, then the airbags simply will not be able to last their service life and will fail ahead of time.
Malfunctions also include collisions with various obstacles, when the support bracket itself may be damaged. In addition to this, oil or antifreeze leakage that gets onto the rubber base of the cushion can also reduce the service life of the support. Plus, there is a high thermal load in the engine compartment with simultaneous splashes of cold water.
Signs of a faulty support
A failed gearbox cushion will make itself felt with characteristic signs. So, when driving or braking the car, unpleasant clicks, jolts, knocks, squeaks and noise will appear in the area of the front of the car.
When driving over various uneven surfaces, shocks will again appear in the front of the car, as well as vibration and feedback to the gear shift lever. Plus, when the support wears out, a characteristic squeaking and clanging sound often appears and can interfere with speed.
On rear-wheel drive car models, if the gearbox mounts are worn out, shifting gears will be difficult, plus the car will vibrate while in motion.
A support malfunction can also be determined by structure-borne noise, for example, when starting and stopping the engine, as well as when the load changes.
Checking status
The condition of the supports can be checked visually. Upon inspection, the product should not show cracks (most often appear along the edges), tears, delaminations, or hardening of the rubber. Sometimes, when hardening, the rubber part peels off from the body of the pillow, which will be visible upon inspection.
When the silent blocks of the gearbox supports wear out, the gearbox linkage fastenings may break, the cushions may become deformed with the appearance of cracks, and eventually the support may burst.
For the presence of backlashes
The malfunction of the gearbox cushion can be determined in the inspection hole or overpass during its inspection. You need to apply force to the box, moving it sideways or up and down, while looking at the condition of the support. You can also apply force to the support using a pry bar. A worn part will “move” with its internal part. The working support in this case will look like a single whole, elastically resisting the applied load.
In addition to the supports themselves, their mounting bolts may fail, which will be visible from the sagging box.
General replacement scheme
Dismantling and installing a new gearbox cushion on most car models can be done with your own hands, without turning to car service professionals. It is enough to have an inspection hole in the garage, not be afraid of dirty work and purchase a minimum list of tools.
To work you must have:
• the necessary set of tools (the list is indicated in the repair manual for this vehicle);
• Safety stands for the engine;
Operating procedure
• The car is placed on the inspection hole, the handbrake is raised and supports are installed under the wheels;
• The battery and battery stand are removed (depending on the design of the car model);
• The body is lifted with a jack, and a reliable piece of board is placed under the power unit across the inspection hole. If the garage has a manual hoist, then only the engine itself is raised;
• Stops are placed on the board and the body is lowered onto them from a jack, thereby unloading the supports;
• The gearbox support fasteners are released and removed;
• Before installing a new cushion, you need to place it on the future location and check the alignment of the holes in the support and the holes in the body. If necessary, you can lower or raise the body a little with a jack;
• A new product is installed, the fasteners are made using the torque prescribed by the manufacturer, and everything is assembled in the reverse order.
Finally
To extend the service life of the supports, we recommend choosing a gentle driving mode, avoiding sudden acceleration and braking. Also, periodically pay attention to the condition of the power unit cushions in order to replace them in a timely manner. It is recommended to check them at every scheduled maintenance or when signs of malfunction appear.
If oil or coolant gets on the supports, clean and wipe them dry, keeping the rubber from corroding.

The main role of the pillow is to dampen vibration coming from the motor.
On VAZ 2110 , eight-valve engines are attached to the body with 3 supports (two side and rear), and sixteen-valve engines are attached to 4 (two side, lower front and upper front).
Features of replacing the VAZ 2110 box cushion
It is possible to carry out repairs yourself. Initially, it is worth purchasing suitable cushions for the gearbox for a VAZ 2110 car (produced by the Volzhsky Rubber Plant). Also, you need bolts, nuts, washers, and a casing bushing.
The main stages of replacing the VAZ 2110 gearbox cushion:
- The car starts up in the inspection hole.
- A beam is placed across the pit, on which the jack is installed (closer to the support).
- Visually you can determine the condition of the support. If it is deformed, the spare part needs to be replaced.
- To remove the pillow, you need to unscrew the nuts that secure it to the box.
- The through fastening bolt is unscrewed.
- The pillow is removed.
Installation of a new spare part occurs in the reverse order. Replacing a pillow on a box does not require any specific skills; this procedure does not require much time.
Thus, replacing the VAZ 2110 gearbox cushion can be done independently. When carrying out this procedure, you need a set of keys and a jack. In normal condition, the products should be solid; components should be periodically checked for integrity. There are many signs that the gearbox cushions have become unusable, for example, vibrations of the gearbox lever, knocking noises when switching from 1st to 2nd gear. The car must be equipped with original spare parts only.

VAZ 2110: replacing the gearbox cushion on your own
Replacing the box cushion
If the car has been in use for more than three years, it starts to knock somewhere and a squeak comes out somewhere. When accelerating or driving on broken roads, a knocking sound begins under the bottom of the car. A knock can also be heard at the location of the gearbox. For a VAZ 2110, replacing the gearbox cushion, which will be discussed in the article, can completely solve the problem. Replacing the VAZ 2110 gearbox cushions is a simple matter that anyone can handle.
Do I need to change
There are no recommendations for replacing pillows depending on their service life, but once you determine that they are faulty, you should not delay replacing them.

Vibration processes can not only worsen the comfort of the driver and passengers, but also lead to destructive processes in the engine or gearbox itself.
Having decided to repair the engine mounting elements, you need to decide whether you will change the pillows
, or support assemblies. In principle, if the metal support itself is not damaged, it can be left, replacing only the pillow.
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.
Note: it is advisable to buy all rubber cushions for repairing VAZ and other car models from these manufacturers, since they use natural rubber in their production. This is not advertising, but years of practice.
- Drive the car into the garage into the inspection pit:
- Connect the lamp with the lantern closed;
- Visually inspect the attachment points of the box cushions. The knock can be produced by the rocker (see Replacing the rocker on a VAZ 2110 on your own), hitting the transverse rod. All due to the fact that the gearbox sagged. The gap from the link to the rod should be more than 5 mm.
Note. You can temporarily eliminate this defect. Take a piece of rubber hose, cut it lengthwise and put it on the drawstring. But this is only for temporary use.
When there is enough time, it is necessary to replace the gearbox mounting pads. It is advisable not to delay this. If the box is sagging, you need to find the cause and eliminate it. First, try tightening the left mount nut on the gearbox. Due to its spontaneous unscrewing, the engine and the gearbox sag. If this operation does not help, then you need to change it.
Diagram, design of the VAZ 2110 gearbox. Replacing the airbag, signs of malfunction.
Manual gearboxes have proven themselves to be reliable and unpretentious devices, but even such “hardware” can have faults. Finding the problem can be quite difficult, since there are a lot of parts in the VAZ 2110 gearbox. After reading this material, motorists will be able not only to identify a defect in the operation of the gearbox, but also to independently study how the circuit is designed, the design of the VAZ 2110 gearbox and solve the problem. As an example, we will consider the most common malfunctions that owners of “cans” have to face.
Gearbox - device and location
The VAZ 2110 has a five-speed manual transmission with two shafts. There are two main tasks of the checkpoint:
- Speed change - due to a change in torque, speed modes are switched.
- Direction of movement - shifting to reverse gear causes the crankshaft to spin in the opposite direction, as a result, the car goes backwards.
The box in the VAZ 2110 car consists of two shafts - the drive and driven, which are also called the primary and secondary. Each ox has a block of gears, due to which the torque is adjusted. Also in the gearbox housing there is a main gear (using a clutch it is connected to the crankshaft) and a differential. The mechanism for changing speeds is a lever that goes into the car interior. To get to the box, you need to remove the fasteners both in the hood and under the car. Together with the engine, the transmission forms the power plant.
Diagram of the VAZ 2110 gearbox: faults and solutions
Some defects can be eliminated with your own hands, but to do this you need to learn to determine which defect is interfering with the normal operation of the gearbox. The main faults are listed below:
- The lever is loose. The cause may be worn-out gearbox and motor cushions. Also, other parts may be the “culprits”. Below are instructions for replacing the cushions and lever.
- Noise in the VAZ 2110 gearbox when switching. There may be several reasons: parts are worn out, poor lubricant is used or its level has dropped below the minimum, or water may have gotten into the working fluid. In the case of worn parts, only replacement will help. As for the lubricant, its quality and the presence of water in it can be checked with a dipstick.
- The gears are switched off randomly. This defect appears when parts wear out - an inspection is necessary to determine the cause of the spontaneous shutdown. The malfunction also appears due to incorrect operation of the drives that need to be adjusted.
Advice! In order not to waste a lot of time searching for faults, it is recommended to take the car to a service station, where professionals perform diagnostics. Subsequent repairs and replacements can be done by yourself.
Functionality check
Before you start replacing the pillows, it is recommended to check whether they have really lost their functionality. It is likely that vibrations can occur for other reasons.
To check you need to do the following operations:
- Place the car on stands;
- Place a jack under the oil pan, placing a block or board at the same time;
- Raise the engine until the mounts relieve the weight of the engine;
- Check the pillows;
- Inspect them for cracks;
- Check if they come off easily from the metal backing;
- Has the original hardness of the material been preserved, or has it become too elastic;
- If no visual defects are found, check the play between the plates and the frame;
- Treat the cushions with protective compounds, return the engine to its place;
- Sometimes, to return the supports with cushions to normal operation, it is enough to tighten the fastening nuts.
If the check shows that the pillows have already served their purpose, then the only correct solution is to replace them. These elements are not subject to restoration.
Replacing the pillow
The important point here is to look for a worn-out pillow. To find out which one to change, the VAZ 2110 must be jacked up and then placed on supports. Next, the jack needs to be placed under the pallet. To protect yourself while working, you need to place a wooden block between the jack and the pallet. The motor must be removed from the support and hung. Now you can inspect his pillows and find the defective one. Due to a damaged cushion, not only the lever dangles, but the entire interior dangles - the level of comfort drops noticeably. A new pillow will cost about 200 rubles.
Replacement proceeds as follows:
- The negative terminal is disconnected from the battery. The VAZ 2110 must be lifted with a jack;
- Next, the engine needs to be raised so that you can get to the damaged cushion;
- The next step is to unscrew the through bolt that holds the support;
- Once removed, the mount can be disconnected from the power plant. Before installing a new cushion, the bolt must be treated with a fixing sealant, and then secured in its original place. Done, replacement complete.
For sixteen-valve engines
Removing and replacing side airbags is done in the same way as for 8-valve engines.
Work to replace the front lower airbag is carried out from underneath the machine.
- Unscrew the bolt securing the front lower support rod to the front suspension cross member (15 wrench).
- Unscrew the nut of the bolt fixing the support to the engine bracket (2 wrenches x 15). Remove the bolt
. - Remove the support, replace the pillow or the entire structure.
- Carry out installation in reverse order .
- In the engine compartment, unscrew the bolt securing the upper front support to the body, holding its nut with your hand (17 wrench).
- Remove the bolt
and nut. - Unscrew the bolt securing the front upper support to the engine bracket (15mm wrench). Remove the bolt
and nut. - Remove the support, replace the pillow or the entire structure.
- Install it in reverse order .
