Replacing RA bearings as of model year 2008 

→ Avoid small bending radii when routing lines.

→ File down edges and burrs in the routing area or mask them with adhesive tape.

→ Maintain a sufficient distance from components exposed to high temperatures while driving.

For vehicles with PDCC (Porsche Dynamic Chassis Control)

• The vehicle only moves if the engine is running.

1. Move the gear support → under the centre of the chassis sub-frame and lift it carefully using a suitable base (e.g. hard rubber support).

2. For vehicles with PDCC: Unclip the lines from the holders on the body so that there is sufficient clearance at the lines for lowering the chassis sub-frame.

   Information 

   Front rear-axle bearings: The cardan shaft must not touch the mounting face when lowering the suspension sub-frame! -Arrow-

3. Loosen the threaded joint at the bearing and carefully lower the gear support until there is sufficient clearance for using the tool.
4. Press out chassis sub-frame bearing.

   CAUTION: Heavy components

   • Risk of squashing

   → Wear personal protective gear.

   → Get someone to help if necessary.

   Information 

   Hold the hydraulic cylinder VAS 6178 tightly while pressing it out.

5. Attach the tools as shown in the picture and press out the bearing.

   Information 

   When inserting the bearing, make sure that the rubber cushion is pointing in the direction of travel in the transverse direction.

6. Check the chassis sub-frame installation position (rubber cushion -arrows-  ).

7. To avoid damaging the bearing, the maximum → Pressure: 60 kN+/-5 kN  must not be exceeded at the stop (60 KN = 200 bar). This conversion applies only to the hydraulic cylinder VAS 6178. The conversion depends on the diameter of the cylinder in question. Assembly fixture T10301 Porsche supplement set T10301/20 

   Information 

   The nut -2-  must be locked in the process with the contact surface on the press-in plate -7-  ! The press-in plate -7-  must be positioned perfectly on the bearing sleeve on the chassis sub-frame. (Get another worker to help if necessary!) This prevents the bearing from being drawn in at an incorrect angle.

8. Connect the tools together as shown in the instructions. Press the bearing in carefully.

   Information 

   Observe correct tightening torques.

9. Carefully lift the chassis sub-frame until the installation position is reached. Fit the threaded joint on the chassis sub-frame bearing.
10. For vehicles with PDCC: Clip the lines into the holders on the body. → WM 4303AW SAFETY REQUIREMENTS FOR PORSCHE DYNAMIC CHASSIS CONTROL (PDCC)
