Removing spring strut
1. Disconnect plug connections at the wheel carriers and pull out the plugs. Undo plug connection at the wheel carrier (M6 screw) and unclip electric wires at the spring strut.
2. Loosen holder for brake line/brake hose at the wheel carrier. Undo brake caliper from wheel carrier (do not open brake system) and suspend it in the wheel arch.
3. Loosen the drive shaft at the transmission. Slide a protective hose over the drive shaft to prevent damage to the drive shaft.

4. Loosen suspension/stabiliser -1- at the anti-roll bar.
Control arm at wheel carrier
Loosen toe and control arm -2 and 3- on the wheel carrier. Use the press-out tool P 9560 for pressing out the ball joint. When loosening the lock nuts, counter at the ball-joint pin with a screwdriver P 9546 (Torx screwdriver).
To pull the ball-joint pin out of the wheel carrier, pull the control arm down evenly with both hands while swivelling the wheel carrier outwards. Enlist the assistance of a second person for this step.
5. The parking-brake cable must be disengaged at the parking brake lever in the passenger compartment in order to remove the spring strut. Disengaging the parking-brake cable includes:
Releasing the parking-brake lever (do not operate again until fitting is complete! Self-adjusting!).
