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 ALC system.

To disconnect an air tube from a shock absorber, rotate the spring clip 90 degrees 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 90 degrees 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. Refer to Vehicle Lifting.
2. Remove the intake air filter from the vehicle.
3. Disconnect the vehicle harness connector from the air compressor connector.





4. Remove the two nuts, the two bolts, and the air compressor assembly from the vehicle.





5. Disconnect the air tube from the air dryer.
6. Remove the bolt and the harness tie with the air tube from the heat shield.





7. Remove both rear wheels. Refer to Tire and Wheel Removal and Installation.
8. Disconnect the air tube from the left and right rear shock absorbers.
9. Remove the two metal clips from the air tube and the vehicle.
10. Remove the air tube with the three clips from the vehicle.


INSTALLATION PROCEDURE





1. Install the air tube onto the vehicle with three clips.
2. Connect the air tube to the left and the right rear shock absorbers.
3. 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.
4. Install both rear wheels. Refer to Tire and Wheel Removal and Installation.
