To loosen the piston rod nut at the top of the suspension strut, the workshop uses a special tool to tighten the nut to the correct torque. In extreme cases, you can use a ring key here.
During this operation, the vehicle must be on wheels.
Remove plastic cover (2) from the top of the suspension strut.
Mark the mounting position of the suspension strut bearing (1) strokes (arrows).
Loosen the 22mm piston rod nut while holding the piston rod with a 7mm hex wrench.
Remove the suspension strut bearing after loosening the three nuts by 13 mm.
Turn the steering wheel like this. so that the piston rod can align with the bearing disc. To do this, you can clamp a piece of wood between the spring and the wheel arch.
Pull the rubber buffer off the piston rod.
Unscrew the shock absorber cartridge nut in the depth of the strut using tool 2069 (or as described), pull the shock absorber cartridge up.
The car with the cartridge removed can no longer be moved, because. the spring can fly out, which is very dangerous.
During subsequent assembly, make sure that the marks on the suspension strut bearing match the marks on the suspension strut, otherwise you will have to adjust the angles of the front wheels.
Tightening torques:
- shock absorber cartridge nut - 18Nm
- nuts on the suspension strut bearing - 30 Nm
- nut on the shock absorber piston rod - 60 Nm
Use new self-locking nuts!
