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 automatic level control 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 the fitting groove.
