The rubber mounts on the Lada Vesta muffler are torn. What to do?

Functions and replacement of Lada Vesta corrugation

The corrugation is also called a compensator, because thanks to its movable structure it serves to reduce engine vibrations, thereby compensating for the loads that arise during its operation.

The corrugated element is also tasked with reducing the sound volume when the engine is running and protecting the Lada Vesta body from vibrations.

We will tell you in detail about the reasons why the corrugation fails, how to identify problems and carry out replacement correctly in our article later.

Elastic connection device

The quality of the part may vary. There are two-layer and three-layer corrugations. The service life and quality of the functions performed by the corrugated element depend on this. Three-layer parts last much longer and are much more durable than two-layer parts.

The braid on the part can be single or reinforced double. At the same time, the corrugation becomes more resistant to external damage. When hitting an obstacle, an element of the exhaust system can withstand the impact and not break.

The flexible connection of the muffler parts on the Lada Vesta protects it from overheating and, consequently, burning out.

The part is made of high-strength stainless steel.

New "gingerbread"

You can buy new muffler mounts for Lada Vesta in many regular auto stores or online. You can take both rubber and polyurethane parts. However, before placing an order in an online store, it is recommended to clarify what exactly the “gingerbread” is made of, since the material is not always indicated in the product description.

The most popular offers are presented in the table.

As you can see, the price of mounting a muffler on a Lada Vesta is very low, and therefore the purchase of such a component will definitely not be burdensome for the budget.

The modification process is demonstrated in the video.

In addition, it would be a good idea to check the strength of the heat shield, as it may touch the muffler and make a sound, as shown in the video.

Causes of failure and replacement of the Vesta muffler corrugation

The corrugated element can fail for several reasons, sometimes beyond the control of the driver:

• quality of gasoline at domestic gas stations. The exhaust system is damaged by fuel additives that are added to increase the octane number. True, such elements, rather, worsen the fuel mixture and render the catalyst unusable, and after it the corrugation;
• chemicals on the roads in winter can damage any metal and shorten the life of parts of the Lada Vesta exhaust system;
• a clogged catalyst that does not perform its functions, and the entire load falls on the corrugation;
• a bottom impact and mechanical damage to the part can happen even with a new, just installed corrugation;
• engine mounts have become unusable;
• The muffler mounting is outdated and the system sags, which creates tension in the corrugation and leads to its rupture.

How to replace an old-style muffler with a new one on a Lada Vesta

Previously, we talked about how the muffler of the Lada Vesta family was modernized at the factory several times. Additional mounting supports have been added to the design of the exhaust system, which extend the life of the corrugation. Owners of cars with an old model muffler can modify the design by installing a new model muffler. We'll tell you what you need for this.

One of the LADA auto centers reported to the Lada.Online website that in mid-2022, LADA dealer centers received an order from AVTOVAZ. It reported that when Lada Vesta owners contact the problem of “rupture of the muffler corrugation”, the additional muffler 8450031143 (with two attachment points) should be replaced under the warranty with an additional muffler of a new type (with three attachment points) 8450034009.

To do this, you will additionally need a crossbar with a hook (part number 8450030210), which is secured with 2 bolts instead of part No. 20 in the diagram.

LADA dealerships note that after the introduction of the new type of mufflers, the number of requests from owners with the problem of “corrugation rupture” has become significantly less.

For those who have installed the very first muffler with one “horn” mounting 8450104547, such a modification is not suitable. In this case, you can replace the muffler with the same one or an analogue from Lecar.

Will you modify the design of your car in this way?

Diagnosis of breakdowns in a car service center

If you suspect a breakdown of the elastic connection, you should check the exhaust system as soon as possible to avoid its sudden destruction while driving.

It happens that the problem has just begun, and it is not clear where the gas is coming from into the cabin. To do this, start the engine, take a bottle of soapy water and water the corrugation. If there is damage to the corrugation, then the water will hiss and foam in that place. Consequently, the driver of the Lada Vesta contacted the service on time.

If there are problems with the oxygen sensor, the lamp will light up, indicating a problem in the exhaust system.

Methods for replacing corrugations on Lada Vesta

Corrugation repairs are not performed. Only requires replacement. This will protect the car from more serious damage and save the driver’s time.

• buy cheap parts;
• change the Lada Vesta corrugation on your own without using high-quality welding;
• repair the breakage by wrapping the fabric over the break site. Such actions are temporary and allow you to wait a couple more days before repairs. There is no guarantee that the exhaust system will not collapse during this time.

Sometimes heat-resistant adhesive is offered as an alternative to welding. This method of installing a new corrugation is not recommended, since the temperature of the gases can be very high, and the glue will soon melt. The property of the glue is such that the more heat-resistant it is, the more prone it is to cracking and falling off.

Problem solving

Contact an authorized dealer. When contacting a service center, the vehicle will be subject to a diagnostic examination and the cause of the symptoms will be identified. If it is necessary to replace parts, specialists place an order for a new car muffler element. You will have to wait 1.5-2 weeks. After this, a replacement is made.

Replace the part yourself

Doing the work yourself requires ordering a new part. Car owners replace the standard component with an extended one. Many people, along with the corrugation, replace the standard exhaust pipe and muffler, which rattles too much. Sometimes car owners carry out modifications. This option is suitable for those who do not have the opportunity to install a new part, and have difficulties when contacting an official dealer. Refinement will not require money, physical resources or time.

There are two ways to improve

Replacement process in a car service

There are rules for installing a new corrugation on a Lada Vesta car:

• you need to cut off the old part closer to the edges;
• after removal, clean the cuts and remove rust;
• It is necessary to cut smoothly for high-quality further welding.

When removing and replacing the corrugated connection on a Lada Vesta, it is necessary to inspect the pipe for damage or burns. At the same time, diagnose the catalyst. Replace if necessary. To avoid damage to the second oxygen sensor, it is temporarily removed during repairs and also inspected.

bracket

Some owners reported a similar problem under warranty and, to the credit of the dealerships, not only the appropriate replacement was carried out, but the cause was also determined.

It lies in the fact that the steel brackets on the muffler holder bar and on the exhaust itself are not coaxial. This arrangement leads to the fact that the load does not go to the entire suspension, but only to one side of it, which provokes the rapid occurrence of cracks.

The photo shows that the fasteners are not aligned

This is not a defect, but simply a minor but unpleasant flaw by AvtoVAZ engineers.

As you can see, the cracks appear on one side.

To fix the problem, just bend the pins in the right direction and install a new “carrot”.

Factory response to this problem

Following the growth in car sales, the number of people contacting AvtoVAZ representatives with complaints about the presence of uncharacteristic sounds and symptoms of a muffler malfunction has increased.

AvtoVAZ representatives commented on the situation as follows: the cause of the hum may be a feature of a particular sedan model, in which the muffler is in contact with the surface of the body. The result is a hum and rattling sound. Experts advised that if symptoms of product malfunction appear, do not overcook the mufflers, but contact an authorized dealer. If the service center refuses to carry out diagnostic or repair work under warranty, you must contact the company management with a description of the problem and the name of the center that refused the driver.

Fixing the fastening plates

In this case, replacing the muffler mounts on the Lada Vesta may be necessary due to an insufficiently thought-out arrangement of the muffler suspension brackets. The fact is that these plates are installed close to the body. Consequently, the vibration that comes from the exhaust is transmitted to the body, which can also cause sounds.

To get rid of this problem, it is recommended to install gaskets between the body and the mounting plates. To do this, you can use rubber washers or spacers.

Causes

In this case there are three reasons:

1. The quality of the products is not high enough, since the muffler pads for the Lada Vesta are standard Priora ones.
2. AvtoVAZ miscalculation in the location of the brackets;
3. Fixing the fastening plates.

In general, if you eliminate the miscalculation with brackets and plates, the service life of the “carrots” increases noticeably.
