Installing
Note:
When installing, make sure that the retaining lugs engage properly.
CAUTION!
The bonded rubber bushings can only be turned to a limited extent.
The bolted connections between the shock absorbers and the rear
axle should therefore only be tightened when the vehicle is standing
on the ground. Otherwise the bonded rubber bushings will be
subjected to a torsional stress resulting in shortened service life - Turn suspension strut until retaining lugs are positioned above
recesses.
- Pull suspension strut downward out of its mount.
- Install in reverse order of removal.
- Replace gasket on upper spring plate. Thoroughly clean all sealing
surfaces
