The rear suspension of the car is dependent and includes a guide device, elastic elements and devices that dampen body vibrations.
Guide device. The rear axle beam is connected to the body by means of reaction rods: two lower 3 and two upper 17 longitudinal and one transverse rod 24. The longitudinal rods transmit pushing and braking forces from the drive wheels through the rear axle beam to the body. The transverse rod prevents the body from lateral displacements. The reaction rods are attached to the body brackets and the rear axle beam through rubber-metal hinges, which are structurally identical and differ only in size. The hinge consists of a rubber bushing 2 installed in the rod eye, a spacer sleeve 1, which passes through the hole in the rubber bushing, a thrust washer and a rod mounting bolt.
The elastic elements of the suspension consist of coiled cylindrical springs 9, two main compression buffers 6 and an additional compression buffer 16. The springs under a static load of 295 kgf are sorted into two groups A and B. The groups are marked similarly to the groups of front suspension springs, i.e. group A - with a yellow stripe, group B - with a green one. The spring installed on the suspension rests with its upper end on the support cup 10 through a rubber insulating gasket 11, which is placed in a stamped steel cup 12 of the body. The lower end of the spring rests on the cup 5 of the rear axle beam through an insulating plastic gasket 4. The main buffers 6 are installed inside the springs and are secured with a mushroom-shaped nipple in the holes of the upper supports 10. The additional buffer 16 is mounted on a bracket bolted to the bottom of the body.
The damping device consists of two hydraulic shock absorbers, the design of which is described in subsection 6.3.

Rear suspension springs under a load of 3185 N (325 kgf) are divided into two groups: group A springs - length greater than 278 mm, marked with light brown paint; group B springs (length equal to or less than 278) – are marked with blue paint on the outer side of the turns.
