A complete set of VAZ 2114 chassis elements
The chassis of the car includes two suspensions - front and rear. During operation of the machine, most of the load falls on the chassis. The quality and comfort of the ride, as well as the safety of the driver and passengers, depend on the condition of the front and rear suspensions. The main function of each suspension is to eliminate vibrations and soften the ride. Also, the tasks of the chassis include reducing roll when turning, ensuring a smooth ride, and providing high information content for the driver in the city and on the highway.
On the roads of the CIS countries, the chassis is subject to excessive load, since the condition of the road surface leaves much to be desired. As a result, motorists often turn to car service centers. Things are better with the VAZ 2114, since it has more modern systems compared to previous Lada models. Many motorists choose to solve the problem on their own. But in order to understand what has gone wrong, you need to know the suspension structure.
What's included in the rear suspension?
The image below shows all the main elements of the rear suspension that can fail.
Rear suspension diagram of VAZ 2114
- The first part is a rubber-metal hinge, which is the main attachment to the car body.
- A bracket used to secure the rear suspension arm to the body.
- Shock absorber housing.
- A buffer that takes the load from the compression stroke.
- Casing cover.
- Main support washer.
- Shock-absorbing cushion.
- Spacer sleeve.
- Strut (shock absorber).
- Insulation gasket.
- Solid spring.
- Connecting element for levers.
- Beam lever.
- Bracket for fastening the rack structure.
- Flange.
- Lever bushing.
The beam structure includes a connector and two trailing arms; these elements are indicated in the diagram as numbers “12” and “13”. The parts are fastened together by welding. In the rear part, flanges (number “15”) and brackets for attaching struts (shock absorbers) are attached to the levers. The axles of the rear pair of wheels along with the brake elements are screwed to the flanges. Bushings (16) are installed on the rear suspension arms at the front. They are fastened using rubber-metal hinges - number “1”. One end of the spring rests on the support through a rubber gasket, and the other on the shock-absorbing cup.
Disassembling and replacing the rear suspension: instructions
The main parts of the rear suspension are highlighted in color
A complete disassembly of the rear suspension is required if the motorist decides to lubricate all the parts or change them. Most often you need to get to a specific element and replace it. The parsing proceeds as follows:
- The VAZ 2114 is installed under an inspection hole, or, as an option, on a lift. In the luggage compartment, the rear and side trims and the seat belt retractor are disconnected. Also in the luggage compartment there are fastenings for the racks to the car body. They need to be loosened; there is no need to unscrew them completely.
- Next, the fastenings of the rear wheel pair are loosened. To do this, you need to remove the hubcaps and then completely dismantle the wheels. Reliable jacks should hold the car at this time; they are usually installed on each side.
- Now it is necessary to dismantle the brake system cables. You need to get them assembled. To do this, the cable fastenings to the suspension arms and the body of the VAZ 2114 are disconnected. Afterwards, the brake drums are dismantled. The cable ends should be removed from the manual drive levers. You also need to disconnect the flanges from the brake flaps.
- Before dismantling the hoses and pipes of the brake system, care must be taken to prevent leakage. Next, you need to dismantle the elastic drive lever, which is used to operate the brake pressure regulator. To remove the lever, you need to disconnect it from the bracket by removing the lock washer, then remove the shackle from the wheel axle.
- The next step is to disconnect the struts (shock absorbers). To do this, remove the rubber cushions, nuts attaching to the body part and the washer. After this, you need to install additional stops for the front wheelset. The rear part should be raised. After this, you can remove the compression stroke buffers, springs and shock absorber covers.
- If you disconnect the body mounting brackets, the entire beam can be detached. The rear suspension along with the struts will lie in front of the motorist. If necessary, you can disassemble the shock absorbers, which is no longer difficult.

IMPORTANT. The shock-absorbing spring must be removed using special ties. If they are not used, serious injury may occur as the iron spring is under high pressure.
How is the rear suspension disassembled?
To repair the rear suspension of a VAZ 2114, you need to know how to disassemble it correctly. We will tell you how to do this correctly below.
To begin with, the car must be placed above the inspection hole or raised using a lift. In the trunk, you need to disconnect the rear and side trim, as well as the seat belt retractor. Also here you need to find the fastenings of the struts to the car body and loosen them, but do not unscrew them completely.
Then you need to loosen the rear wheel mounts by removing the hubcaps and completely unscrewing the wheels. The machine must stand on reliable jacks - one on each side.
Front pillar
Remove the brake system cables. They should be removed as an assembly by disconnecting the cable fastenings to the chassis arms and body. After this, you need to remove the brake drums. Remove the ends from the manual drive levers and disconnect the flanges from the brake flaps. Before removing brake hoses and pipes, be careful not to leak. Next, remove the elastic drive lever, which is necessary for the operation of the brake pressure regulator. To remove the lever, disconnect it from the bracket by removing the lock washer, and then remove the shackle from the wheel axle.
Disconnect the shock absorbers by removing the rubber cushions, body mounting nuts and washer. Next, support the front wheelbase and lift the rear. Having done this, you can remove the compression stroke buffers, shock absorber covers and springs.
Once the body mount brackets are detached, you can remove the entire beam. In front of you will be a rear suspension with risers. If necessary, disassemble the shock absorber - this will not cause any special problems.
To remove the shock-absorbing spring, you will need special ties. Without them, you could be seriously injured because the spring is held in place under high pressure.
Front suspension device
The main element of the front chassis of the VAZ 2114 is the shock absorber strut, which is designated as number “9”. It is attached to the steering knuckle with two bolts. Compared to the rear system, the front suspension has a more complex design, which can be understood by the number of parts. Number “11” indicates a bolt that passes through the holes of the rack bracket; it has an eccentric washer and an eccentric collar. When the steering gear turns, the top bolt turns. The result is that the car turns. Most often, shock absorber struts fail, since they do the main job.

Repair of the front suspension stabilizer of VAZ-2114
This element of the front suspension of the VAZ-2114 is designed to reduce the roll of the car when cornering. The part does not have a complex structure and consists of a flexible beam, as well as a pair of silicone silent blocks. The element has a small stroke, which ensures vehicle stability on the road.
Attached to the front side members with the central part. The side parts are connected to the suspension arm on the “knuckles”. The stabilizer has a long service life - more than 100 thousand kilometers. Usually it is the silent blocks that fail. But to replace them you need to remove the stabilizer completely. Below we will tell you how to do this.
If your car has lost its former maneuverability and strange noises have appeared in the front end, inspect the condition of the stabilizer. Perhaps the silent blocks in it have worn out. How to replace them? To do this you need:
- raise the front of the car;
- remove the bolts securing the struts from the right and left wheels;
- remove the bracket fixing nuts;
- remove the stabilizer assembly.

Old silent blocks can be removed by hand. Before installing new ones, you should thoroughly clean the area of dirt. As reviews note, polyurethane silent blocks have a longer service life than silicone ones. And in cost they are almost the same. Therefore, when purchasing silent blocks, you should give preference to polyurethane elements.
Disassembling and replacing the front suspension: instructions
- The VAZ 2114 is installed on a viewing hole or raised on a lift. The car must be set to the parking brake. It is necessary to remove the wheel caps, loosen the mounting bolts and unscrew the hub nut. Having secured the front of the car, you can remove the front wheels.
- Next, you need to remove the ball joint pin, which is located in the swing arm of the front strut. The next step is to remove the front stabilizer link (number “24”) from the front suspension arm (number “22”). Next, the stretch marks from the body (30) are removed. Next, you need to completely disconnect the ball joint that is attached to the steering knuckle.
- Now you can remove the front suspension arm. To do this, you need to disconnect it from the body bracket (28). Afterwards the lever is removed along with the bracket and the extension (29, 30). It is also necessary to remove the bolts that secure the pads to the steering knuckle.
- In front of the driver there will be a caliper assembly. To avoid problems with it, you do not need to completely remove it; you need to hang the caliper on a hook in such a way that there is no load on the main hose. The next step is to press the spline shank out of the front wheel hub.
- From the side of the engine compartment, you need to remove the protective fist (“41”). To do this, unscrew the telescopic strut nuts and then remove the solid front suspension strut. It should be together with the wheel hub and steering knuckle. The other front suspension strut is removed in the same way. Next, the racks are removed from the rod.
Removing springs using zip ties
When removing the bolts that secure the ball joint to the steering knuckle, you must use a socket wrench. Otherwise, the protective cover of the hinge may be seriously damaged, resulting in additional costs.
In the case of the front suspension, its assembly proceeds in the reverse order, with the exception of a few features. When installing the mounting bracket to the VAZ 2114 body, you need to make sure that the threads of the bushings are not damaged. To do this, you must perform operations carefully. Also, longitudinal displacement of the cushions on the bar must not be allowed. This can happen during installation of the anti-roll bar.
How to replace?
Usually the racks are replaced in pairs or as a whole. To do this, jack up the front of the car and remove the wheels. Next, release the rack from its mounting with the steering tip. Then unscrew the two nuts that secure the shock absorber to the suspension arms. The bolts are removed by hand from the reverse side. If they are rusty, you can use a hammer and attach a wooden block. Next you need to open the hood and loosen the upper fastening of the strut, which is in the cup.

In this case, you should hold the stand from below so that it does not fall. After this, the suspension module is removed entirely. A new element is installed in its place. Assembly is carried out in reverse order.
At the front, the VAZ-2114 uses independent wishbone suspension. These elements ensure the transmission and absorption of shocks that occur when the car hits an uneven surface. The front suspension arms of the VAZ-2114 are made of high-strength steel XK-60, so they can easily withstand high loads. The element is attached with one part to the ball joint, and the other to the body on a bracket.
Also, the lever must be replaced in case of a serious collision with a hole (in which the disk was bent) and after an accident. Otherwise, due to deformations, there will be problems with wheel alignment, as well as constant tire waste. How is the front suspension repaired on a VAZ-2114? Usually the entire lever changes, as does the strut. The cost of a new element is from 700 to 1 thousand rubles. The lever is interchangeable with the first generation Lada (that is, the “nine”).
To do this, raise the front part of the car (alternately on each side with a jack). Next, unscrew the nut securing the ball joint and, using a puller, remove the ball joint pin from the lever. Next, unscrew the nut securing the extension. The stabilizer link is disconnected from the lever. Next, unscrew the nut that secures the suspension arm to the body.
