Installation Procedure
- Clean the lower control arm pocket of debris to ensure that the rear air spring can be fully seated on the lower control arm.
- With the rear air spring collapsed, position the rear air spring (1) in the lower control arm.
- When installing the air spring it is important that the top and bottom of the air bladder form folds (1) hiding the crimping collars.
- If installed incorrectly the crimp collars (1) will be exposed and failure of the air bladder will occur.
- Install the air tube fitting (1) to the air spring and tighten to 2 (18 lb in).
- Snap the 2 retaining clips (2) into place on the upper rear spring seat (1).
- Lower the vehicle, but DO NOT allow the tires and wheels to touch the ground.
- Pressurize the air suspension system. Refer to Air Suspension System Depressurization and Pressurization .
- Continue to lower the vehicle to load suspension.
- Start the vehicle and run for approximately (1) minute to ensure that the rear air spring is completely pressurized and functioning properly.
- Raise the vehicle and check for leaks at the air line fittings, using a spray bottle filled with a soapy water solution.
- Lower the vehicle .
Ensure that the air spring is fully seated and properly positioned on the lower control arm. Failure to properly position the air spring may cause the air spring to break apart, possibly resulting in personal injury or damage to the vehicle.
When properly positioning the air spring , the top and bottom of the flexible air bladder should form folds that hide the metal crimping collars where the bladder attaches to the top and bottom mounts. If these folds are not formed and the metal crimping collars are visible , the bladder will likely separate.
Do NOT exceed the torque value on the air supply fitting, over tightening may cause the plastic threads in the air compressor or the air spring to become stripped, permanently damaging the air spring compressor or air spring.
Refer to Fastener Caution .
Do NOT pressurize the air springs/shocks under load or damage to the air spring/shocks will occur. Always pressurize the system with the wheels of the vehicle off the ground.
