REPAIR PROCEDURES:
Installation of Rear Alignment Shims
1. Block front tires so vehicle will not move.
2. Release parking brake.
3. Hoist vehicle so that rear suspension is in full rebound and tires are off the ground.
4. Remove wheel and tire assembly.
5. Pry off grease cap.
6. Remove cotter pin and castle lock.
7. Remove brake drum/disc retaining nut.
8. Remove brake drum/disc.
9. Loosen four (4) brake assembly and spindle mounting bolts enough to allow clearance for shim installation. Do not remove mounting bolts.
10. Using a maximum of two (2) shims per spindle, install the shim(s) (as shown in Figures 1, 2, 3, and 4) to bring the alignment as close as possible to the preferred camber and toe specifications. Each shim changes alignment (camber or toe depending on shim installation position) by .3~.
