Rear suspension parts
1 - lower longitudinal rod; 2 - rubber bushing; 3 – an arm of fastening of the bottom longitudinal bar to a body; 4 - spacer sleeve; 5 - upper longitudinal rod; 6 - additional compression stroke buffer; 7 - spring; 8 - the upper cup of the spring; 9 - compression stroke buffer; 10 - the upper insulating gasket of the spring; 11 - shock absorber; 12 - the lower insulating gasket of the spring; 13 - transverse rod
Removing
1. Raise the rear of the car and place on stands. Remove rear wheels.
2. Disconnect the propeller shaft from the final drive gear flange.
3. Disconnect the brake hydraulic hose from the steel tube mounted on the axle and take measures to prevent leakage of fluid from the brake system.
4. Disconnect the parking brake rear cable bracket from the body, remove the front cable retracting spring and, by unscrewing the lock nut and adjusting nut, release the rear cable branch. Disconnect the rear brake pressure regulator drive link from the bracket on the axle beam. Disconnect the upper ends of the shock absorbers.
5. Place a hydraulic jack under the rear axle beam. Disconnect the longitudinal and transverse rods from the brackets on the body, lower the jack and remove the bridge.
6. Proceed to disassembly of the suspension:
- remove the shock absorbers from the brackets on the axle beam;
- Disconnect the longitudinal and transverse rods from the brackets on the bridge beam.

1 – body spar; 2 - cross bar bracket; 3 - rear axle beam; X = 125 mm
Installation
1. Installing the rear suspension is carried out in the reverse order of removal.
2. At the same time, install springs of the same class on the suspension as on the front suspension. In exceptional cases, when class A springs are installed on the front suspension (with yellow marking), and for the rear suspension there is no such class of springs, it is allowed to install class B springs on the rear suspension (with green marking).
3. To prevent damage and over-tightening of the elastic bushings of the hinges of the rods and shock absorbers:
- load the rear of the vehicle so that the distance from the axle beam to the body side member, measured at 100 mm from the cross bar bracket, is 125 mm;
- tighten with a torque wrench the nuts on the bolts for attaching the longitudinal and transverse rods, as well as on the pins for attaching the shock absorbers to the axle beam and to the body.
