Removal Procedure
- Raise the hoist until it just contacts the vehicle body, without raising the vehicle. With all four tires on the ground, maintain the vehicle as close as possible to it's normal height. If the tires are lifted off the ground , the depressurizing command will not function. Refer to Lifting and Jacking the Vehicle .
- Depressurize the air suspension system. Refer to Air Suspension System Depressurization and Pressurization .
- Raise the vehicle to suitable working height.
- Depress both plastic tabs securing the air compressor filter into the frame rail during removal.
- Using an appropriate tool, remove the air compressor filter (1) from the frame rail.
- Slowly loosen the air tube fittings (1) from the compressor assembly until all the residual air is out of the system.
- Disconnect the air suspension compressor air fittings.
- Disconnect the air suspension compressor electrical connector (1).
- Remove rear air spring compressor bolt (1).
- Support the rear exhaust near the resonator, using a transmission jack .
- Remove the two nuts attaching the front and rear sections of exhaust at the flange, before the resonator. Refer to Exhaust Muffler Replacement (FWD) , Exhaust Muffler Replacement (AWD) .
- Lower the exhaust enough to access the rear air spring compressor nuts.
- Remove the rear air spring compressor nuts (3) and (1).
- Remove the rear air spring compressor (2) from the vehicle by sliding the compressor assembly rearward.
- Inspect the rear air spring compressor bracket insulators, replace if necessary. Refer to Rear Air Spring Compressor Bracket Insulator Replacement .
WARNING:
Do NOT remove an air compressor tube in an attempt to depressurize the air suspension. Always follow the Air Suspension Depressurization Procedure in Air Suspension. Failure to follow this procedure may cause personal injury or damage to the air compressor and/or air spring tube fittings.
CAUTION:
Ensure that you depress both plastic tabs that hold the air compressor filter into the frame rail while removing; failure to do so will result in damage to the air compressor filter.
NOTE:
After depressurizing the air springs and compressor there will still be some residual pressure present. DO NOT quickly disconnect air tube fittings.
