WM 407719 Removing and installing front anti-roll bar (PDCC)
Technical values
Preliminary work
1. Raise the vehicle -> 4X00IN Lifting the vehicle Service and Repair.
2. Remove front-axle support -> 400819 Removing and installing front-axle support - section on "Removing" 400819 Removing and installing front-axle support.
Removing front anti-roll bar
WARNING
Wheel bearing housing raised incorrectly
- Risk of squashing
- Risk of damage to components
-> Wear personal protective gear.
-> Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels).
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.
Overview
1. Support anti-roll bar using mounting jack.
2. Place a suitable container underneath to catch any emerging Pentosin.
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.
3. Detach lines -3-.
Detaching lines
3.1. Loosely screw in cap screws -1-.
3.2. Unscrew clamp -2-.
3.3. Secure lines -3- to prevent them falling down and close them off with suitable plugs.
3.4. Remove lines -3-.
4. Screw off fastening nuts -2- for suspension/stabiliser -1- ( -arrow- ).
Securing suspension/stabiliser
5. Press suspension/stabiliser -1- outwards.
6. Remove anti-roll bar.

Information
The anti-roll bar must be positioned before tightening the fastening screws of the anti-roll bar support (=front-axle support) so that the highest point of the anti-roll bar is positioned at a distance from the frame support (not the fold!) of -Z-.
The dimension -Z- is => Control value: 86 mm.
Installation dimension of PDCC anti-roll bar
This ensures that the position of the anti-roll bar in the support corresponds to the normal vehicle position.
Information
- All the threaded joints on the axle must be tightened in vehicle position. Vehicle position means: vehicle standing on its wheels, or the wheel suspension is raised using a universal vehicle lift. Dimension -X- , from lower edge of wing to middle of axle corresponds to vehicle position. For details of current height values, see -> 4495TW Adjustment values for suspension alignment 4495TW Adjustment values for suspension alignment. Always observe the following points!
Dimension X - centre of wheel to lower edge of wing (rear axle shown)
Steel springs
- The vehicle position is reached at the front axle by placing the vehicle onto the wheels in a suitable work area (wheel alignment platform, workshop pit).
Air suspension
- The vehicle position is reached at the front axle (with air suspension) by bleeding the respective air spring using the Porsche System Tester and carefully lifting the respective wheel bearing housing. -> 4301IN Bleeding and filling the levelling system 4301IN Bleeding and filling the levelling system
- Use an intermediate layer (hard rubber)! Do not damage the brake cover plate.
Raising wheel carrier (air suspension)
- Screws and nuts are Geomet-coated and must not be greased.
- Grease the toothing of the drive shaft slightly with aluminium paste Optimoly TA.
- Drive shafts must not be left hanging from the joint stop! Tie up.
- Use new screws and lock nuts.
- Use correct tightening torques and torque angles. -> 4X00IN00 Tightening torques for front axle
1. The anti-roll bar is installed in reverse order to removal.
2. Observe correct tightening torques. -> 4X00IN00 Tightening torques for front axle-> 4X00IN Tightening torques for levelling system [1][2]Specifications
