Briefly about the important: the chassis of the VAZ 2107
Content
The chassis of a car is a complex of various mechanisms and components that allow the car not only to move on the surface, but also make this movement as comfortable and safe as possible for the driver. The rear-wheel drive "seven" has a simple chassis design, however, in case of damage and defects, specialist assistance may be required.
Chassis VAZ 2107
The chassis of the VAZ 2107 consists of two suspensions: on the front and rear axles. That is, each axis of the machine has its own set of mechanisms. An independent suspension is mounted on the front axle, and dependent on the rear axle, since the car is equipped with rear-wheel drive.
The operation of these components is designed to ensure a smooth and smooth ride of the car.. In addition, it is the suspension that is responsible for the integrity of the body while driving on rough roads. Therefore, the performance of any element is very important - after all, the slightest inaccuracy in the function of any part can lead to serious damage.
Front suspension
The front suspension on the "seven" is completely independent. Its composition includes:
- top position lever;
- lower position lever;
- stabilizer, responsible for the stability of the machine;
- small accessories.

Roughly speaking, it is the lever elements and the stabilizer that are the connecting passage between the wheel and the body shell. Each of the wheels of the front pair is mounted on a hub, which rotates easily and without friction on bearings. In order for the hub to hold securely, a cap is put on the outside of the wheel. However, this equipment allows the wheel to rotate only in two directions - forward and backward. Therefore, the front suspension necessarily includes both a ball joint and a steering knuckle, which help the wheel turn to the sides.
The ball joint in the design of the VAZ 2107 is responsible not only for turns, but also for minimizing vibration from the road. It is the ball joint that takes on all the blows from hitting the wheel in a pit or when hitting a road obstacle.

To ensure that the ride height does not decrease while driving, the suspension is equipped with a shock absorber. To adapt the "seven" to Russian roads, the shock absorber is additionally equipped with a spring. The spring “winds” around the shock absorber, creating a single whole with it. The mechanism is installed strictly vertically to ensure maximum clearance in all driving conditions. Such a mechanism perfectly withstands all road troubles, while the body does not experience strong vibrations and shocks.
The front part of the chassis also has a cross member. It is this part that connects all the suspension elements together and brings them to work with the steering column.
The front suspension takes on the weight of the engine, and therefore experiences increased loads. In this regard, its design is complemented by more powerful springs and weighty swivel elements.
Rear suspension
All elements of the rear suspension on the VAZ 2107 are mounted to the rear axle of the car. Just like the front axle, it connects a pair of wheels and provides them with rotation and turns.
The wheels of the rear pair are mounted on the hubs. However, a significant difference from the design of the front suspension is the absence of rotary rotary mechanisms (cam and support). The rear wheels on the car are driven and completely repeat the movements of the front wheels.
On the reverse side of each hub, a brake cable is connected to the wheel. It is through the cable that you can block (stop) the rear wheels by simply lifting the handbrake in the cabin towards you.
To protect against impacts from the road, the rear suspension is equipped with shock absorbers and separate springs. At the same time, the shock absorbers are not directly vertical, as on the front of the chassis, but are slightly inclined towards the rotation gearbox. However, the springs are strictly vertical.
Immediately under the springs on the inside of the axle there is a fastener for the longitudinal bar. There is a gearbox that provides the transmission of rotation from the gearbox to the rear wheels. In order for the gearbox to keep its performance for as long as possible, the designers of AvtoVAZ assembled the rear suspension together with the cardan shaft: during movement, they move synchronously.
On VAZ 2107 models manufactured after 2000, instead of shock absorbers, special shock-absorbing systems are installed. Such a system includes springs, cups and hydraulic shock absorbers. Of course, modern equipment makes the course of the "seven" smoother even on the most dead roads.

How to check the chassis on the "seven"
Self-checking the running gear of the VAZ is a relatively simple and quick procedure. No special tool is required, however, it is necessary to drive the car onto a flyover or pit.
Checking the chassis involves a visual inspection, so you will need to take care of good quality lighting. During the inspection, it is necessary to carefully examine all suspension units, paying special attention to:
- the condition of all rubber elements - they should not be dry and cracked;
- the condition of the shock absorbers - there should be no traces of oil leakage;
- integrity of springs and levers;
- the presence / absence of play in the ball bearings.
This check is quite enough to find a problematic part in the chassis of the car.

The chassis on the VAZ 2107 has a fairly simple structure. An important fact can be considered the possibility for self-diagnosis of chassis faults and ease of diagnosis.
