Rear spring tip liners should be installed to service spring squeak on these vehicles. A service spring clip is available if the original clip is damaged during tip liner in stallation. Refer to Figure 18 during installation.
Tip Liner Installation:
Raise the vehicle by the frame so that the rear axle hangs freely.
Bend the spring clip to provide clearance between the spring leafs, allowing insertion of the liners. A pry-bar may be used between the leaves to provide additional clearance for insertion of liners.
Slide the liner between the leaves until the liner ex tends approximately 0.25 inches beyond the tip of the lower leaf. Do not attempt to install a liner be tween the lowest primary leaf and the short, 0.50 inch thick secondary leaf found at the bottom of the leaf stack on some assemblies.
Set the rear axle on a stand to load the rear leaf springs placing the leafs in contact with one another at the clip locations.
Reinstall production clips or install the replacement service clip.
NOTE: On some of the tip liners, sections of the edge used to center the liner on the spring leaves may need to be trimmed off to ac commodate the spring clip.
Service Spring Clip Installation:
Load the rear leaf springs with the rear of the vehicle

out of the locating hole. (Locating holes are the holes punched out of the lowest leaf the clip en circles which indicate the proper spring clip location.)
Make sure the locating hole is clean and free of residual matter.
Position the lower part of the service clip across the width of the underside of the spring, such that the hole in the clip lines up with the locating hole in the spring. The legs of the clip lower half should extend down from the bottom of the spring.
Insert !l:ie drive rivet that comes with the clamp through the hole in the lower part of the service clip into the hole in the spring leaf. The flat face of the rivet flange should rest against the clip lower half.
Fully upset the rivet with a hammer. If there is not enough room to hit the rivet directly with a hammer, a punch may be used. The slotted legs of the clip lower half should extend downward, the outer sur face of the legs flush with the sides of the leaf spring.
Place the rubber service clip liner across the top of the leaf spring, directly above where the bottom half of the clip attaches to the spring, with the flat sur face against the leaf and the clip locating edges ex tending upw ard.
Place the clip upper half between the locating edges of the rubber liner and align the threaded holes in the clip upper half with the slots in the clip lower half.
Hand start the two screws through the clip lower half slot into the clip upper half threaded hole. The screw heads will be located under the spring, ultimately pressing against the inner surface of the clip lower half.
Squeeze the clamp to the spring with one hand while tightening the screws. Torque to 1 5-20 ft-lbs. ( 20.5 - 27 N-m).

supported, either directly by the rear axle or by the tires. The spring leaves should all be in contact with one another at the intended clip location.
Remove the damaged clip by prying back the ends of the clip which are folded across the leaf spring until the clip can be freed from the spring. On some clips it will also be necessary to pry the locating pin
