Rear Air Suspension


Air Suspension Servicing

Pipe Disconnect
  1. Before servicing the vehicle, refer to the Precautions section.
  3. If it is necessary to disconnect a pipe:
    1. Wear hand, ear and eye protection. Wrap a cloth around the connection.
    3. Clean the connection with a stiff wire brush.
    5. Peel back the boot.
    7. Apply equal downward pressure on the collet flange (A) as shown.

    9. Pull the pipe firmly through the center of the collet.
    11. To connect the pipe, push it firmly through the 2 O-rings until it contacts the base of the housing. Gently pull back on the pipe. Some slight movement will be noticed.
    13. Reposition the boot.


When the job is done, run the engine to repressurize the system. The system must be recalibrated using the TestBook tool. Recalibration must be done on a floor surface that is level and smooth in all directions.


The air suspension is pressurized up to 150 psi (1034 kPa). Before beginning work on suspension or steering components, the system should be depressurized. A special tool called a TestBook is required to depressurize the system properly and safely. The tool is self-guiding. Depressurizing will lower the suspension to the bump stops. Before beginning any work, make sure that all air springs are deflated. A spring that remains inflated is due to a stuck solenoid valve. In that case, it will be necessary to disconnect the pipe at that air spring.
