Removal

Note! If the car is equipped with Four-C (Continuously Controlled Chassis Concept), replace the spring.

Removing the spring strut





Remove:
- the wheel
- the anti-roll bar link from the spring strut.

Note! Use a Torx wrench as a counterhold so that the boot is not damaged.

Remove the ABS line from the bracket on the spring strut.

Measure the spring strut position in relation to the wheel spindle before removal





Note! The measurements are taken so that the same camber angle can be obtained when installing.

- Measure across the wheel spindle/spring strut at the upper screw as illustrated
- Before measuring, clean off any dirt from the measuring surfaces
- Note the measurement.

Removing the spring strut




- Remove both the nuts from the screws in the spring strut - wheel spindle.




- Remove the two screws for the spring strut wheel spindle.
- Secure the wheel spindle with a piece of wire so that it cannot turn outwards when removed from the spring strut.





Remove:
- the three nuts holding the shock absorber support plate in the bodywork
- the spring strut.

Removing the shock absorber bearing

- the nut for the shock absorber bearing. Use socket 999 5467 SOCKET 999 5467 Socket and a 3/8" Torx-wrench as a counterhold.
- the washer
- the support.

Removing the spring




Relieve the load on the spring seat using hydraulic tool 951 2911 Hydraulic piston 951 2911 Hydraulic Piston together with plates 951 2914 Claw 951 2914 Claw.

Remove:
- the fixing nut on the shock absorber. Use socket 999 5469 SOCKET 999 5469 Socket and a 3/8" Torx-wrench as a counterhold.
