In case of repair, shock absorbers of any manufacturer can be installed, provided that their markings are observed, for example, "H2 orange" (H2 orange).
Removal
1. Disconnect the trunk trim fasteners and remove it.
Attention! Shock absorbers serve as a stop for the rear wheel spring. Therefore, it is better to disconnect the upper shock absorber mount with the car standing on its wheels. If the car is raised, the suspension arm should be supported, otherwise the axle will fall out. When unscrewing the upper mount, the shock absorber piston rod should not turn, since the working cylinder mount may unscrew and an accident may occur.

2. Unscrew the nuts (75a). If the piston rod rotates, hold it from turning by the flats with an open-end wrench. When unscrewing the lock nut, hold the lower nut with a 17 open-end wrench.
3. Raise the car from behind.

4. Where available, remove the suspension arm cover (72c) by unscrewing the 2 bolts (72d).

5. Unscrew the nut (75I) on the suspension arm and remove the bolt with washer (75h).

6. Remove the shock absorber (75) from the suspension arm (72) and from the body support base. If this is difficult, press the shock absorber with a screwdriver through the hole in the arm, then pull the shock absorber downwards.
Installation
1. Check the shock absorber before installation.
2. Check rubber parts for porosity and damage, replace if necessary.

3. The new shock absorbers are supplied complete with a stop buffer (75i), protective cap (75f), rubber support (75d) and a dimension bushing (75k).
4. Install the shock absorbers with the color markings facing backwards.
5. Install the bolt (75h) and tighten it with a new self-locking nut to a torque of 55 Nm.
6. Screw on the suspension arm cover.
7. Slowly lower the vehicle while inserting the shock absorber into the upper mounting hole.

8. Place the rubber ring (75c) and washer (75b).
9. Screw both nuts (75a) onto the shock absorber rod. Screw the lower nut all the way in with a torque of 15 Nm, and tighten the lock nut with a torque of 30 Nm. Make sure that the piston rod does not turn, holding it by the flats if necessary.
10. Place the trunk trim and snap the fasteners into place.
