5 ways to solve the problem with the right engine mount of Lada vesta » Lada.online - all the most interesting and useful about Lada cars

Depending on the batch, different engine mounts are installed on Vesta (VAZ 21129). In some cases, it may cause extraneous noise (knocking, clicking, rattling). Let's figure out how to eliminate this drawback with your own hands.

How are engine mount knocks transmitted in Vesta’s cabin:

To determine whether the upper right engine mount is the cause of the knocking, you need to slightly rock the engine to the sides, as shown in the video:

Currently, there are no AvtoVAZ regulations on this problem. Therefore, when contacting an official dealer with such a defect, there cannot be an unambiguous solution. According to the owners' reviews, in some cases the dealer sent data on this malfunction to AvtoVAZ (you need to wait for a response), in other cases they replaced the upper engine mount with an alternative, more rigid one.

You can also get rid of the knocking with a simple modification. It is necessary to lubricate the engine mount with silicone grease (WD-40 will not work) in the places where the rubber comes into contact with the metal housing. Photo of the upper right engine mount of Vesta:

After this the knocking should go away:

Despite the fact that the VAZ 21129 engine (1.6 l, 106 hp) is also installed on the Lada XRAY, the upper right mount of the power unit has a different part number (on Vesta - 8450030109, on XRAY - 112107286R), accordingly, this problem is not observed on the crossover.

Let us remind you that knocking noises in the front part of Vesta can come from the brake caliper or suspension, for example, from anti-roll bars.

The engine is the holy of holies of any car, and therefore, when extraneous sounds begin to be heard from under the hood, car owners immediately sound the alarm and try to figure it out.

Rear cushion

This support is located at the bottom of the rear side of the motor. It is designed to reduce engine vibrations, as well as suppress knocking and dampen vibrations.

To dismantle it, you will first have to remove the protection of the power unit. When this is done, you need to unscrew the nut with an 18mm wrench while holding the bolt so that it does not turn.

Next, using the same 17mm wrench, unscrew the bolt marked in Figure No. 1, and then loosen the bolt marked No. 2. All that remains is to remove the bolt and remove the support.

When tightening, the prescribed torque is from 90 Nm to 120 Nm.

As you can see, replacing the Lada Vesta and X-Ray engine mounts yourself is quite possible and does not require a large number of tools.

Examination

It is not difficult to assess the need to replace the engine mounts of the Lada Vesta and X-Ray. This requires looking under the hood and visually inspecting the cushions for damage - breaks in rubber components, cracks in metal, etc.

In general, if you experience the following symptoms, you should consider replacing:

During a sharp start or when braking with the power unit, knocking noises are heard from under the hood;
Vibrations are felt while the engine is running;
The cabin fills with noise when driving.

The steps described below are relevant for two engines - VAZ 21129, as well as HR16, which were installed under the hood of the XRAY and Vesta models.

The sound of the engine mounts can be clearly heard in the video.

Solution options

In fact, there are several of them.

Contacting the dealership

In the event of a visit to the dealer, there is, as a rule, no clear solution to the issue of knocking from under the hood of the Lada Vesta. It all depends on the specific salon. Some centers simply refuse to replace them, citing the fact that this is not a warranty case. Others sent information about the defect directly to AvtoVAZ, but this is a rather lengthy procedure, and therefore not everyone agrees to wait that long. And the answer is not always positive.

Knock of the engine mount on cars of the Lada Vesta family

Some owners of Lada Vesta family cars began to notice noise and knocking coming from the engine compartment of their car. After long disputes with official dealers and between the owners themselves, the hero of the occasion was identified. It turned out to be a car engine support (pillow). In most of these cases, the noise came precisely from the right engine mount, after the owners went en masse to official centers with this problem, and also began writing appeals directly to AvtoVAZ, the manufacturer confirmed the possibility of this problem occurring on some cars, as well as sent an information letter to the showrooms of official dealers. This letter contains information about identifying a problem with the engine mount, as well as methods of elimination, mainly replacing the defective spare part. So if your car is under warranty and you suspect the engine mount is not functioning properly, feel free to go for diagnostics to an official dealer, where this defect will be corrected for you.

Solving the problem becomes more expensive if the car’s warranty has expired or it is not possible to visit an official dealer. First, you need to establish whether the engine mount is exactly to blame for the extraneous noise from the engine compartment; to do this, we follow the instructions taken from the AvtoVAZ information letter.

The knocking sound of a faulty engine mount can be heard from the driver's and front passenger's seats; the sound itself emitted by the mount is muffled and occurs when the engine oscillates transversely. To reproduce a knock, do the following:

We accelerate to 30 kilometers per hour and brake, repeat several times, make turns and hit a small curb (actions that can cause engine vibrations)
Sharp acceleration from a stop and subsequent braking.

When performing the above steps, a dull knock should be heard, if this does not happen, most likely the cause of the extraneous noise in your car is not related to the engine mount.

If, after carrying out diagnostics, you are also sure that the engine mount is faulty, you need to inspect it for defects. Defects can be both obvious (cracks in rubber, metal wear) and hidden (large gaps).

By the way, AvtoVAZ sentences the cushion to be replaced if the gap is more than 2 millimeters; in all other cases, silicone grease is applied to the right and upper contact surfaces of the bump stop. Lubrication occurs at the will of the owner and is paid according to the price list.

Also, to solve the problem on their own, the owners lubricate the engine mount themselves; this is done only with the help of silicone grease; WD-40 and similar chemistry are powerless here. It is worth noting that this solution is temporary and you will still have to replace the pillow in the future.

Information letter No. 41-19

When owners of Lada Vesta cars contact with the defect “knocking in the right engine mount”, it is necessary to carry out diagnostic work in accordance with the application. The decision on the warranty of the declared defect is made based on the results of the work performed.

When replacing the “right engine mount” part 8450030109 in a LADA VESTA vehicle, AGO, register according to code 1001089-096-000 “right mount knock” in compliance with the requirements of regulations No. 9-16 and No. 83-18. In the descriptive part of the AGO, indicate the parameters for measuring the gaps between the bump stops and the side wall of the “right engine mount”.

according to the assessment of the declared defect, 0.2 n/h, (item 87003*1);
for lubrication of bump stops 0.05 n/h. (position 87001*1);
for replacing the right engine mount 0.3 n/h, (item 10130*1).

Problem

As sad as it is to realize, West owners are not spared this problem either. Many owners notice knocking noises under the hood of the Lada Vesta, and they come from the right side.

As a rule, you don’t have to search for long, since the situation is well known. It appears on sedans that were equipped with engine mounts from the VAZ 21129. As a result, a whole cacophony of sounds began to be heard from the engine compartment, including knocks, clicks, squeaks, etc. Moreover, these sounds are so loud that they can be heard even in the cabin.

The knock from the support is quite loud

And the best confirmation of this is numerous videos in which owners of the domestic model demonstrate trouble.

And in this video you can hear knocks directly inside the car.

In addition, some owners began to “dig deeper” and found out that a similar situation occurs not only on Vesta, but also on other models of the Renault-Nissan Alliance. In particular, on the Nissan Qashqai. This is also confirmed in the video.

As for the Lada X-Ray, the hatchback has not noticed such a problem, even though its engines are the same as those on the sedan. The whole point is that X-Ray is equipped with different supports for the power unit.

Left pillow

The left engine mount of Lada Vesta and X-Ray is fixed to the body with 4 bolts. Also, the cushion is attached to the gearbox bracket with 2 bolts. In turn, the bracket is fixed to the gearbox housing using 3 bolts.

Replacing the part is complicated by the fact that access to it is blocked by several components at once - the crankcase protection, the filter (air) mount, and the battery shelf. Therefore, to get to the support, all this will have to be dismantled.

First you need to unload the cushion, for which you slightly raise the gearbox using a jack.

Next, using a 16mm wrench, unscrew the 4 bolts that secure the left engine mount to the body.

Then, using an 18mm wrench, you need to unscrew 2 more bolts that secure the cushion to the transmission bracket. Once this is done, the part can be removed.

Assembly is carried out in reverse order.

Replacing the right engine mount

The right cushion is attached to the side member with two bolts, and three bolts to the engine. Remove the engine splash guard and raise the right side of the engine using a jack. Then:

Replacement of the right engine mount VAZ 21129

Examination

In general, if you experience the following symptoms, you should consider replacing:

During a sharp start or when braking with the power unit, knocking noises are heard from under the hood;
Vibrations are felt while the engine is running;
The cabin fills with noise when driving.

The steps described below are relevant for two engines - VAZ 21129, as well as HR16, which were installed under the hood of the XRAY and Vesta models.

The sound of the engine mounts can be clearly heard in the video.

How to check engine mounts

The first sign of a strut malfunction is a knocking sound coming from the engine compartment. To pre-confirm this “diagnosis”, check for the following signs:

A hum is heard in the cabin when driving at high speeds.
When starting the Lada Vesta engine when cold, metallic tapping is heard in the cabin and strong vibration is felt.
When accelerating sharply or braking sharply, knocking noises are heard from under the hood.
A knocking sound from the left engine mount of the Lada Vesta is less common, but the final conclusion can be made by visually inspecting the cushions. A good rubber-metal part should be completely free of damage, so that the rubber does not make a knock when it comes into contact with metal - this way it does not absorb shocks.
Rock the engine and then press on each corner to identify the worn pad that needs to be replaced. Wait until it cools down before touching the motor.

The knocking sound of the upper engine mount on Vesta is common

It is important to point out the knocking of the Lada Vesta engine mount, which carries a greater load than the other two - this is the upper (or lower) cushion. It is located in the center and does not dampen the vibrations that come to the left or right edge of it, which is why it quickly becomes loose. The design can be modernized by adding a special pillow for the sports version.

How to change airbags on a Vesta car

In order to correctly adjust the engine mount, it is not at all necessary to go to an official dealer - contacting him will still result in the installation of exactly the same part.

Replacing the left engine mount

Before work, prepare and “clear” your way to the part: remove the battery, battery shelf, air filter mount and crankcase protection from under the hood; all components will have to be put aside and then reinstalled. The Lada Vesta cushion itself is attached to the side member on the body with four bolts, and to the gearbox bracket with two bolts. In order not to worry about the reliability of the structure, make sure for yourself that this bracket is attached to the gearbox housing with three bolts.

The replacement procedure is as follows:

Jack up the gearbox - this will reduce the load on the cushion, because the jack will “take” it.
Using keys 16 and 18, unscrew all the bolts that are responsible for fastening the pillow. When retightening the mounting bolts to the side member, stop at a torque of 53-71 Nm.
As for the mounting bolts to the bracket, their tightening torque is 90-120 Nm.
Remove the right engine mount.
Place the new part in place of the old one and tighten the bolts until you are sure that the structure is stable.

Replacing the right engine mount

Depending on the engine model: HR16 or 21129, the design of the right airbag of the Lada Vesta is different. In the VAZ 21129 engine, the right support is located next to the spar, to which it is attached with two bolts, and the engine itself, to which it is attached with three bolts.

The HR16 engine has a slightly different design, and the part can be found next to the fuel pipe and the gasoline vapor recovery system pipe. Three bolts secure its body to the motor, two more hold the bracket. This power unit support in the Lada Vesta is located on the right.

To replace, unscrew all the fastening bolts (depending on what kind of “engine” is in your car) with a 16mm wrench and a TORX E12 wrench and remove the pillow itself.

When you assemble the structure, tighten the bolts to a force of 53-71 Nm.

Replacing the rear additional engine mount

This part is installed below, on the rear side of the motor. The mounts are different on the two types of motors. On the 21129 engine of the Lada Vesta, it is “tied” into a large network of fasteners. So, on one side it is held in place by a bracket that is firmly supported by two bolts. On the other hand, it is attached to the subframe with a bolt and nut. On the HR16 engine, the fastening is simpler: on one side, one bolt secures the part to the subframe, on the other, two bolts secure it to the gearbox.

To replace, unscrew all bolts and remove the rear cushion. On motor 21129, be careful with the bracket fastening bolt - loosen it last and “catch” the pillow.

When putting the structure back together, tighten the bolts to 90-120 Nm.

You can do the work of replacing the power unit supports yourself. After tightening the bolts, check the strength and stability of all racks - they should not wobble excessively and should not stand “tight” - they should have a small amplitude of movement. Proper bolt torque will keep the motor in place and reduce vibration. To ensure the reliability of new parts, you can modify them by lubricating them (wd-40 will not work here).

Right pillow

Replacing the engine mount of the Lada Vesta and X-Ray begins with dismantling the mudguard of the power unit, after which the engine must be jacked up on the right side. The support itself is fixed to the spar using 3 bolts.

For dismantling you will need:

Using a 16mm wrench, unscrew the 2 bolts that secure the cushion to the body.
Remove the 2 bolts that secure the cushion to the power unit bracket. A TORX E12 bit is used for this.

When everything is done, you can remove the support.

Installation proceeds in the reverse order, and the bolts should be tightened in the range from 53 Nm to 71 Nm.

As for the right motor mount of the HR16 series, it has a slightly different layout.

Manufacturers and prices of analogues

The cushions for Lada Vesta engines are considered by owners to be not particularly reliable and are even being modified to increase the effect of vibration absorption.

Otherwise, there are no special attempts to create analogues, because the “craftsmen” have already drawn the attention of Vest owners to two modification options:

Came from Renault owners. It is necessary to create for each problematic pillow a metal plate 80 mm long, 38 mm wide and two grooves on the sides measuring 23 mm wide and 38 mm deep. The funny thing is that the X-Ray, which is in many ways similar to the Vesta, has the same engine (21129), but there are no problems with the upper right support - it’s just different.
If the part itself is still intact, it can be lubricated with silicone grease where the rubber hits the metal body.

Wear

The wear of the engine mounts is determined by the “crampedness” of those points of the metal body that take the blow, damage and the thickness of the layer itself - rubber will not dampen vibrations if its thickness is very small.
