Removing rear anti-roll bar (PDCC)
WARNING
Caustic fluids
- Danger of chemical burns
-> Avoid contact with caustic fluid.
-> Wear personal protective gear.
-> Ensure that there is good ventilation.
-> If you do come into contact, wash off immediately with plenty of warm water and contact a doctor if necessary.
Information
PDCC chassis:
- Steel flexi-pipes are particularly sensitive to kinking and crushing.
- Treat the steel flexi-pipes with great care when removing, storing and reinstalling the anti-roll bar.
- Make sure that the steel flexi-pipes are not subject to any mechanical loads during the following operations.
- When removing, mark the installation position of the lines using a touch-up stick.
- When installing, make sure that the clamp is seated correctly.
- The steel flexi-pipes must not be twisted when installed under any circumstances.
Information
- The pictures shown in this document may differ from the original.
- However, this does not affect the validity and relevance of the pictures.
1. Mark the installation position -arrow- of the anti-roll-bar mount halves with respect to the anti-roll bar with a paint marker.

Information
The anti-roll bar halves can turn following removal and hydraulic fluid will leak out.
- Close the openings in the anti-roll bar using suitable plugs or screw plugs.
3. Remove the union nuts -9- on the two lines at the rear valve block. Use a container to collect emerging fluid and close off the lines using suitable stoppers.

Information
- All screws and bolts on the axle must be tightened in vehicle position. Vehicle position means: vehicle standing on its wheels, or the wheel suspension is raised with a universal vehicle lift. Dimension -X- , from lower edge of wing to centre of axle corresponds to vehicle position. For the current height values, please refer to the adjustment values for suspension alignment -> 4495TW Adjustment values for suspension alignment 4495TW Adjustment values for suspension alignment.
Dimension X - lower edge of wing to centre of axle (shown as an example)
- Visually inspect all parts.
- Replace self-locking nuts.
- Replace all expansion screws (screws fitted using torque angle tightening procedure).
- Use correct tightening torques and torque angle. -> 4X00IN Tightening torques for rear axle 4X00IN Tightening torques for rear axle
4. Fit the anti-roll bar and insert the four fastening screws evenly in vehicle position and tighten hand-tight.
5. Fit the fastening nuts for the anti-roll bar at the connecting links and tighten hand-tight.
6. Clip the two lines for the rear valve block into the brackets.

10. Tighten the fastening screws and fastening nuts for the anti-roll bar and connecting links to the specified tightening torques -> 4X00IN Tightening torques for rear axle 4X00IN Tightening torques for rear axle.
11. Following assembly, check carefully once again that the steel flexi-pipes are not twisted! The toothed rings -arrows- must be positioned on the steel flexi-pipes in such a way that they provide adequate protection in the event of contact with adjacent components.
