Air Line: Service and Repair

At the rear shock absorbers, the air tube connectors are held on with spring clips which snap into the grooves of the shock absorber air fittings. Air tube connectors are sealed using two O-rings.

Important: Before disconnecting any air tube, clean the connector and the surrounding area to prevent dirt and other foreign material from entering the ELC system.





To disconnect an air tube from a shock absorber, rotate the spring clip 90° out of the slots, and pull the connector from the shock absorber.

Important: Ensure that the air tube is routed correctly and all fasteners are used.

To connect an air tube to a shock absorber, lubricate the two o-rings using silicone lubricant, rotate the spring clip 30° into the slots, and push the air tube connector on the shock absorber fitting until spring clip snaps into fitting groove.


REMOVAL PROCEDURE
1. Raise the vehicle.
2. Remove the air tube from the air dryer.





3. Remove the bolt and the harness tie from the air compressor bracket.
4. Remove both rear wheels. Refer to WHEEL REMOVAL.





5. Disconnect the air tube from the left and right rear shock absorbers.
6. Remove the two metal clips from the air tube and the vehicle.
7. Remove the air tube with the three clips from the vehicle.

INSTALLATION PROCEDURE
1. Connect the air tube to the air dryer.

NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

2. Install the air tube with the harness tie and the bolt on the air compressor bracket.
3. Install air tube on the vehicle with three clips.
4. Connect the air tube to the left and right rear shock absorbers.
5. Install two metal clips on the air tube and the vehicle. Place each clip immediately forward of the wheel house fold-over tabs on the LH and RH side of the vehicle.
6. Install both rear wheels. Refer to WHEEL INSTALLATION.

Important: Before driving the vehicle, turn the ignition on and wait approximately 45 seconds. This will permit the ELC system to execute the ARC, ensuring that the air adjustable shock absorbers are filled with residual pressure.

7. Lower the vehicle.
