Anti-Squeak Insert

WARNING: THE ELECTRICAL POWER TO THE AIR SUSPENSION SYSTEM MUST BE SHUT OFF PRIOR TO HOISTING, JACKING OR TOWING AN AIR SUSPENSION VEHICLE. THIS CAN BE ACCOMPLISHED BY TURNING OFF THE AIR SUSPENSION SWITCH LOCATED IN THE REAR JACK STORAGE AREA. FAILURE TO DO SO MAY RESULT IN UNEXPECTED INFLATION OR DEFLATION OF THE AIR SPRINGS WHICH MAY RESULT IN SHIFTING OF THE VEHICLE DURING THESE OPERATIONS.

1. Raise the vehicle by the frame so the rear axle hangs freely.
2. Bend the spring clip to provide clearance between the rear spring leaves, allowing insertion of the rear spring anti-squeak inserts . A pry-bar may be used between the leaves to provide additional clearance for insertion of rear spring anti-squeak inserts.

NOTE: Do not attempt to install a rear spring anti-squeak insert between the lowest primary leaf and the short 12.70 mm (0.50 in) thick secondary leaf found at the bottom of the leaf stack on some assemblies.

3. Slide the rear spring anti-squeak insert between the leaves until the liner extends approximately 6.35 mm (0.25 in) beyond the tip of the lower leaf.
4. Set the rear axle on a stand to load the rear leaf springs. Contact leaves at the clip locations.

NOTE: On some of the rear spring anti-squeak inserts, sections of the edge used to center the liner on the spring leaves may need to be trimmed off to accommodate the spring clip.

5. Reinstall the production clips or install the replacement spring clip.
