We check the chassis and transmission every 15 thousand kilometers.
We perform work on a viewing ditch or overpass.
The running gear parts (wheels, suspension arms, anti-roll bar, rear suspension beam, shock absorbers and suspension springs) and the transmission (front drive shaft) must not have deformations, cracks or other mechanical damage affecting the shape and strength of the parts.
By alternately hanging the front wheels (the car must be firmly fixed on the support post), we check the condition of the wheel hub bearings.
Use support columns only factory-made.
The wheel by hand should rotate evenly, without jamming or knocking.

Holding the wheel in a vertical plane, alternately sharply pull the upper part of the wheel towards itself, and the lower part from itself, and vice versa.
We are convinced of the absence of play (knocking). If there is a knock on the front wheel, we ask the assistant to press the brake pedal. If at the same time the knock is gone, then the hub bearing is faulty, and if the knock remains - then, most likely, the ball bearing is worn out.
The bearings of the hubs of the front and rear wheels are not adjustable and, if there is any play, must be replaced.
To check the serviceability of the ball joint, insert the mounting blade between the suspension arm and the ball joint housing. Do not damage the ball joint cover.

Squeezing the lever with the mounting blade, we monitor the movement of the lever head relative to the ball bearing housing.
If there is play in the connection, replace the ball bearing.

We check the condition of the protective covers of the ball bearings.
Replace ball joints with torn, cracked covers.

… and try to move the lever along its axis and along the axis of the bolt. If the lever moves freely, without effort, it means that the silent block of the lever is very worn or damaged and must be replaced. Tearing, cracking and buckling of the rubber bush of the silent block are not permitted.

We check the condition of the silent blocks of the front and rear ends of the stretch marks.
Breaks, cracking, buckling of rubber of silent blocks are unacceptable.

We examine the pillows of the anti-roll bar and the rubber bushings of the stabilizer struts.
If tears, cracking and severe deformation are detected on the rubber cushions and bushings, they must be replaced.
By hanging the rear wheels one by one, we check the condition of the bearings of the hubs of the rear wheels. The wheel by hand should rotate evenly, without jamming or knocking.
To check the condition of silent blocks of the rear suspension arms…

… insert the mounting paddle in a row between the bracket of the suspension arm and the lever head and try to move the lever in different directions.
If the lever moves freely, without effort, it means that the silent block of the lever is very worn or damaged and must be replaced.

We check the condition of the springs, telescopic racks and shock absorbers of the front and rear suspensions.
Suspension springs must not be damaged. Tears, cracking, and severe deformation of rubber bushings, pads, and shock absorber compression buffers are not permitted.
Leakage of liquid from shock absorbers is not allowed. Slight "fogging" of the shock absorber in its upper part while maintaining the characteristics is not a malfunction.
If the rubber element of the upper support of the telescopic strut of the front suspension is upset or destroyed, the support must be replaced.

… and the internal joints of the front wheel drives, we check the reliability of their fastening with clamps.
Cracked, torn or loose elastic covers must be replaced.
We check the absence of oil leakage from the gearbox through the oil seals of the internal joints of the drives. If there is a leak, replace the seals.
Continuation:
check the steering
