Removing and Installing Off-Road Stabilizer

Removing and installing off-road stabilizer

Preliminary work

1. Connect the Porsche System Tester and in the menu select >> Off-road Stabi (ORS) >> Drive links >> Clock valve VA or valve HA.
2. Raise vehicle at the jacking points provided.
3. Remove the rear muffler.

Removing off-road stabilizer








A - Front stabilizer

B - Rear stabilizer

C - Hydraulic unit

D - Operator control unit

E - Control unit

F - Dipstick

Warning:
Risk of accidents! The Off-road Stabilizer System (ORS) operates at an overpressure of up to 165 bar. Under certain conditions, motions can occur on the wheel carrier (e.g., if the Off-road stabilizers are disengaged when lifting, the button is pressed on the center console, and the wheel carrier is also raised). The stabilizer can close quickly.
^ Danger of crushing in the area of the stabilizers and wheel carriers. Injury and material damage due to raising the wheel carrier 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, connect the Porsche System Tester and in the menu select >> 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 link at stabilizer on left and right. To do this, use a suitable lift to raise the wheel carrier sufficiently for the pin of the connecting link to be pulled easily out of the stabilizer. Use a suitable lift with rubber base in order to prevent slipping.





2. Loosen the lines -arrows- and counter with an open-ended wrench. Seal the lines with suitable plugs. Release the connector.





3. Undo the four fastening screws and remove the clamps.
4. Mark the installation position -arrow- of the stabilizer bearing halves with respect to the stabilizer with a paint marker.





5. Carefully pull out the stabilizer.

Installing off-road stabilizer

Caution:
Increased risk of accidents if the wheel carrier is raised improperly!
^ Injury and material damage 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:
^ 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 506 mm, ±10 mm corresponds to vehicle position.





^ Visually inspect all parts.

^ Replace self-locking nuts.

^ Replace all expansion screws (screws which are fitted with torque angle tightening procedure).

^ Observe tightening torques.

1. Mount stabilizer bearing halves in the correct position on the stabilizer. In the correct position means: The larger outer [diameter] is on the wheel side.





2. Engage stabilizer bearing halves at the take-up points provided -arrow-.





3. Insert stabilizer and fit clamps with the four fastening screws. Mount connecting links at stabilizer.
4. Fit the four stabilizer fastening screws in vehicle position.
5. Fit the lines -arrows- and the connector. Fit the lines -arrows- and counter with an open-ended wrench. Connect the connector.

Subsequent work

1. Fit the rear muffler.
2. Bleed the Off-road Stabilizer System.
