Alignment Procedure

NOTE:
^ Check front sub-frame alignment before caster/camber adjustments are performed.
^ Vehicles that require camber/caster adjustment can be corrected by loosening the front sub-frame retaining bolts and shifting the front sub-frame as required. If further adjustment is required, use the following procedure:





1. Center-punch four spot welds on alignment plate(s).
2. Loosen three nuts attaching front shock absorber mounting bracket to vehicle.





3. Use Rotunda Compound Spot Weld Drill Kit 107-R1000 or equivalent to remove four welds.

CAUTION: Do not cut deeper than necessary to remove alignment plate to prevent damage.

4. Remove three nuts attaching front shock absorber mounting bracket to vehicle.
5. Remove alignment plate.





6. Clean burrs from alignment plate and paint exposed metal on front spring and shock tower and plate.
7. Install alignment plate.
8. Loosely install three front shock absorber mount nuts.
9. Make alignment-camber/caster adjustments.

NOTE:
^ Caster measurements must be made on the LH side by turning the LH wheel through the prescribed angle of sweep and on the RH side by turning the RH wheel through the prescribed angle of sweep.
^ When using alignment equipment designed to measure caster on both the RH and LH side, turning only one wheel will result in a significant error in the caster angle for the opposite side.

10. Tighten three front shock mounting bracket nuts to 30 - 40 Nm (22 - 30 ft. lbs.).








11. Drill three 3.2 mm (1/8 inch) holes through alignment plate and paint exposed metal.

CAUTION:
^ To prevent damage, do not drill deeper than 9.6 mm (3/8 inch) into shock tower.
^ DO NOT DRILL DEEPER THAN 9.6 mm (3/8 inch)





12. Install three pop-rivets 3.2 mm (1/8 inch) diameter x 6.4 mm (1/4 inch) grip range.
