Removing front spring strut

Information

- The steel springs do not apply for the Cayenne Turbo.

- Standard Cayenne Turbo equipment: Air springs with levelling system and vertical adjustment.






CAUTION

Increased risk of accidents if the wheel carrier is raised improperly.

- Injuries and material damage are possible.

-> Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels).
-> When raising the suspension, use a suitable intermediate layer (hard rubber).
-> Do not damage the brake cover plate.

1. Lift wheel carrier carefully to facilitate removal. Use a suitable lift with rubber base => see figure in order to prevent slipping.





2. Unscrew plastic nuts -arrows- on front wheel housing liner.





3. Fix upper axle strut with spring compressor VW 552. This involves tensioning the axle strut slightly because otherwise the top ball joint can be damaged. When doing this, the spring compressor VW 552 => see figure is engaged in the upper opening of the wheel housing (double panel) and in the axle strut and pre-tensioned with the nut. This is only necessary if the same control arm is reinstalled.





4. Release connecting rods at stabiliser. => see figure





5. Undo bolt connecting lower spring strut to axle strut -arrow-.





6. Push protective tube 44 -A- over drive shaft. Release drive shaft at transmission flange and lay down carefully. Use suitable base.





7. Release holder for brake line/combination wire at the top on the wheel carrier.
8. Press out ball joint of wheel carrier tie rod with press-out tool T10187 -B-. Counter with screwdriver 9546 -C-.
9. Press out ball joint of top axle strut of wheel carrier with press-out tool T10187 -B-. Counter with screwdriver 9546 -C-.
10. Remove spring compressor VW 552 -D- , release the 4 M8 fastening nuts from mounting saddle and carefully remove spring strut.

Information





- =>

- Carry out a visual inspection of all parts.

- Replace self-locking nuts.

- Replace all expansion screws (screws fitted using torque angle tightening procedure).

- Observe correct tightening torques and torque angle => Tightening torques for front axle.

- Make sure the bevel pinions from the ball joints are clean. Clean with a lint-free cloth as necessary. Do not use cleaning agent.

1. Carefully insert the spring strut and tighten to mounting saddle (four M8 fastening nuts) with the prescribed tightening torque.
2. Fix upper axle strut using spring compressor VW 552. This involves tensioning the axle strut slightly because otherwise the top ball joint can be damaged. When doing this, the spring compressor VW 552 => see figure is engaged in the upper opening of the wheel housing (double panel) and in the axle strut and pre-tensioned with the nut.





3. For easy fitting, slightly raise the wheel carrier using a suitable lift so that the upper ball pin can be inserted. Use a suitable lift with rubber base => see figure in order to prevent slipping.





4. Fit securing pin for lower spring strut.
5. Fit connecting link on the anti-roll bar.
6. Fit the holder for the brake line/combination wire at the top on the wheel carrier.
7. Fit the drive shaft at the transmission flange. Remove spring compressor, protective tube and base.
8. Fit the ball joint of the tie rod on the wheel carrier.
9. Tighten plastic nuts on front wheel housing liner.
