It is convenient to carry out the work on an inspection pit. But if necessary, you can remove and install the spring and shock absorber of the rear suspension by placing the car on a flat horizontal surface.
To perform the work, you will need an assistant, as well as:
- - inspection pit or overpass;
- - stand;
- - device for disassembling suspension struts.
Shock absorber mount: 1 - protective cover; 2 - compression stroke buffer; 3 - support washer; 4 - spring insulating gasket; 5 - upper support cup of suspension spring; 6 - shock absorber rod mounting cushions; 7 - lower support cup of spring; 8 - shock absorber; 9 - shock absorber mounting bolt; 10 - wheel hub axle mounting bolt; 11 - brake drum; 12 - hub bearing; 13 - wheel hub; 14 - axle; 15 - nut; 16 - lock ring; 17 - dowel pin; B - point for orientation of the shock absorber
Removing the rear shock absorber
Prepare the car for work and hang the rear part of the car on stands.
If there is no inspection ditch or overpass, remove the rear wheel of the car from the side of the shock absorber being replaced.
Fold back the back of the rear seat.
Pry it up with a screwdriver and remove plug
Using a 17 mm open-end wrench, unscrew the upper shock absorber mount nut, holding the shock absorber rod from turning with a special wrench.
Or hold the shock absorber rod with a 6 mm wrench to prevent it from turning, and unscrew its nut with a 17 mm open-end wrench.
Use a magnet to remove the spring washer from the shock absorber rod
Remove the upper support washer
Remove the upper cushion from the shock absorber rod.
Using a 19 key, unscrew the nut of the lower shock absorber mount bolt to the beam, holding the bolt from turning with a key of the same size.
Take out the bolt.
If you have difficulty, knock out the bolt with a punch made of soft metal.
Move the lower end of the shock absorber to the rear parts of the car and remove the shock absorber together with the spring
The spring gasket usually sticks to the body, from where it must be removed and checked for deformations and tears.

Assemble in reverse order
Installing the shock absorber and spring
For ease of assembly, we attach the gasket to the spring with tape or electrical tape, which will facilitate installation, while the end of the spring coil should rest against the protrusion of the gasket.
Put the cover on the cup, while the corrugation of the cover should be put on the cup flange.
Insert the compression buffer into the cover so that its corrugated part is at the bottom.
The end of the lower coil of the spring should rest against the projection of the shock absorber support
To make installation easier, you can put a piece of hose on the end of the rod
The hose will allow you to direct the rod into the hole in the upper support on the body
We install the shock absorber so that the shallower recess (shown by the arrow) for the spring faces the wheel, while the end of the lower coil of the spring on the left side of the car will face the rear of the car, and the right side will face the front.
Fix the lower end of the shock absorber, but do not tighten the nut.
Lowering the car onto the wheel, or jacking up this side of the beam, insert the end of the shock absorber rod into the hole in the body and secure it.
Tighten the lower shock absorber mounting bolt in the "car on wheels" position.
After lowering the car to the ground, rock it vigorously several times.
Tighten to the appropriate torques: the lower shock absorber mounting nut to the beam - 68-84 Nm (6.8-8.4 kgf m), the upper shock absorber mounting nut - 51-63 Nm (5.1-6.3 kgf m).
After driving 100 km, tighten these again threaded connections with the required torques.
