  1. Disconnect the negative battery cable.
  2.  
  3. Loosen the lug nuts on the rear wheel(s).
  4.  
  5. Raise the entire vehicle (no vehicle weight can be on any of the wheels) and support it safely on jackstands. Remove the rear wheel(s).
  6.  
  7. Disconnect the air line by pulling back on the plastic ring, then pulling the air line from the fitting.
  8.  
  9. Disconnect the electrical leads from the solenoid and the height sensor.
  10.  
  11. The solenoid (attached to the shock absorber) has a molded square tang that fits into stepped notches in the air spring housing. The notches provide an air relief position and a retaining position. The retaining position is locked with a retaining clip. To vent the air spring:
    1. Release the retaining clip.
    2.  
    3. Rotate the solenoid to the first step in the housing and allow the air pressure to vent.
    4.  
    5. Rotate the solenoid to the release slot and remove it from the housing.
    6.  

  12.  
  13. Release the upper air spring alignment/retaining clips.

  15. Remove the nut that attaches the lower portion of the spring to the axle.
  16.  
  17. Pry the assembly down, pull the alignment studs through the retaining clips and remove the assembly from the vehicle.
  18.  

To install:
  1. Position the lower stud into its seat in the axle and the upper alignment pins through the frame rail adaptor. Install the upper retaining clips.
  2.  
  3. Loosely install the lower mounting nut.
  4.  
  5. Install the solenoid to the top step in the housing.
  6.  
  7. Connect the electrical lead to the solenoid.

The controller is located behind the right side trunk trim panel.

  1. To activate the right rear spring solenoid, ground Pin 10 (light green with orange tracer) to Pin 19 (gray with black tracer) of the controller connector.
  2.  
  3. Run the compressor for 60 seconds by jumping from Pin 9 (black wire with red tracer) to Pin 19 of the controller connector.
  4.  
  5. Attach the connector back to the air suspension controller.
