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 a suitable working height.NOTE:
After depressurizing the air springs and compressor there will still be some residual pressure present. Do not quickly disconnect air tube fittings.
- Slowly loosen the air tube fittings, from the air compressor assembly, until the air starts leaking from the fittings. Allow all the residual air to leak out of the air springs and compressor assembly.
- Remove the fittings (1) from the air compressor assembly.
- Remove the air fittings (1) from the air springs.
- For AWD vehicles , lower the differential carrier assembly, to allow access to the air tube clips. Refer to Differential Carrier Assembly Replacement
- Remove the 2 air compressor tube retainers (1) from the frame rail.
- Remove the 3 air compressor tubes retainers from the cross member (2).
- Remove the air compressor tube assembly (1) from the vehicle.
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.
NOTE:
Assist in the reassembly of the air tubes to the air compressor, note location of the air tubes. The left side air spring tube is white and is furthest rear on the compressor. The right side air spring tube is black and is closer to the front of the vehicle. The air compressor is stamped with tube locations.
