Warning:
Danger of accident. The Off-road Stabilizer System (ORS) operates at an overpressure of up to 165 bar. If the ORS is not depressurized, movements may occur on the wheel carrier under certain circumstances (e.g. the off-road stabilizers are disengaged when the vehicle is lifted, the switch on the center console is pressed and the wheel carrier is also lifted).
^ The stabilizer can close quickly. Thus there is the danger of crushing in the area of the stabilizers and wheel carriers. Danger of injury and material damage if the wheel carrier is raised incorrectly.
-> Before working on the vehicle, ensure that the ORS is engaged. The indicator light on the center console button must be OFF. If the indicator light is on, follow the following procedure: Switch on the ignition and engage the road driving program >> High Range. The stabilizers must audibly engage.
-> Before working on the ORS, depressurize the system. To do this, close the Porsche System Tester and select in the menu >> Off-road Stabi (ORS) >> Drive links >> clock valve VA or valve HA. The valve clocks (audibly) until the procedure is finished.
-> 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. Release connecting rod right and left. When doing this, raise wheel carrier to the extent that connecting rod fastening pin can be taken out easily. Use a suitable lift with rubber base in order to prevent slipping.
2. Loosen the 2 lines (center in Figure) and counter with an open-ended wrench. Seal the lines with suitable plugs. Remove the plug (left arrow).
3. Undo the 4 fastening screws and remove the clamps.
4. Mark the installation position (arrow) of the halves of stabilizer bearing for the stabilizer with a paint marker.
5. Carefully pull out the stabilizer.

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.
Information:
^ Visually inspect all parts.
^ Replace self-locking nuts.
^ Replace all expansion screws (screws which are fitted with torque angle tightening procedure).
^ The entire threaded parts of the axle must be tightened in vehicle position. Vehicle position means: vehicle standing on the wheels, or the wheel suspension is being raised with a universal vehicle lift. Dimension -X-, from lower edge of wing to middle of axle 502 mm, ±10 mm corresponds to vehicle position.
^ Use an intermediate layer (hard rubber)! Do not damage the brake cover plate.
^ Observe correct tightening torques.
1. Mount the halves of the stabilizer bearing in the correct position on the stabilizer. In the correct position means: The larger outer [diameter] is on the wheel side.
2. Engage at the prescribed take-up points -arrow-.
3. Position stabilizer and mount clamps with the 4 fastening screws.
4. Fit the 2 lines (center in Figure) and counter with an open-ended wrench. Plug in the plug (left arrow).
5. Mount connecting rod.
