Suspension strut/coil spring, removing and installing

Special tools required





- T 10001 shock absorber set
- VAG 1 752/1 Suspension strut clamp
- 3186 Socket insert 21 mm AF
- VAG1752/4 Spring retainer
- 3424 Spreader tool
- V.A.G 1383 A Transmission jack

Removing and installing suspension strut
- Remove wheels.





- Detach coupling link from suspension strut (on both sides of vehicle).
- Pull spring clip out of bracket and detach brake hose.
- Release speed sensor wiring from suspension strut.





- Remove bolt securing wheel bearing housing to suspension strut.





- Insert special tool 3424 into slot (arrow).
- Turn ratchet handle through 90° and pull ratchet handle off 3424.
- Press brake disc in direction of suspension strut by hand.
- Otherwise the shock absorber tube can move off - square and stick in the wheel bearing housing.
- Pull wheel bearing housing off shock absorber downward.





- Remove hex nut for upper shock absorber mounting.

2 - T 10001/8
3 - T 10001/11
4 - T 10001/5

When installing, note the following points in particular:





- Before installing suspension strut, coat suspension strut mounting (arrows) with special lubricant G 294 421 A1.





- Insert suspension strut and secure to suspension strut tower.
- Tightening torque: 60 Nm (44 ft. lbs.)
1 - Commercially available ratchet handle
2 - T 10001/8
3 - T 10001/11
4 - T 10001/5





- Locate suspension strut on wheel bearing housing.
- Using transmission jack, raise wheel bearing housing until it is possible to insert bolt securing suspension strut to wheel bearing housing.
- At the same time, press brake disc in direction of suspension strut by hand, otherwise the shock absorber tube can move off - square and stick in the wheel bearing housing.
- Take out spreader tool - 3424 -.

Further installation of the suspension strut is performed in reverse sequence
