ADJUSTMENT

TIRE INFLATION (COLD)
Before attempting to check or adjust wheel alignment, ensure that tires are properly inflated. Refer to specifications in owners handbook for proper inflation procedures.

CASTER
Generally caster is stated as nonadjustable, and that if not within specifications parts are to be replaced. However, in some instances when slight adjustment will alleviate the problem, adjustment of strut bar nut is permitted.

CAMBER
Camber is nonadjustable. If not within specifications, check front suspension for damage. Repair or replace parts as necessary.

TOE-IN
Position wheels in straight-ahead position. If toe-in is not within specifications, loosen locking nuts on tie rod turn buckles. Rotate buckles until toe-in is within specifications. Tighten lock nuts. NOTE - Adjustment must be made equally to both sides of vehicle to maintain correct wheel lock angles; difference of tie rod length when adjusted should not exceed .20" (5.1 mm).


ADJUSTMENT

TIRE INFLATION (COLD)

(6.5 mkg).

Model 100 - 1) With vehicle equipped with spare tire and full fuel tank, measure caster and camber angle. If not to specifications, remove inner ball joint-to-lower control arm mounting bolt and install camber adjusting tool (US 9020) as shown in Fig. 1. Install and slightly tighten on 8 mm bolt and washer in threaded hole between inner and outer ball joint mounting bolts on lower control arm, then loosen outer mounting bolt. Tighten tensioner bolt on adjusting tool to break loose ball joint, then tighten or loosen tensioner bolt until camber angle is set to specifications.

2) To adjust caster angle, leave camber adjusting tool installed to maintain adjusted camber angle, then install caster adjusting tool as shown in Fig. 1. Adjust caster angle to specifications by moving ball joint forward or backward by means of adjusting tool. Hold adjusting tool stationary and tighten outer ball joint mounting bolt to 80 ft. lbs. (11 mkg). Remove caster and camber adjusting tools and tighten inner bolt to 47 ft. lbs. (6.5 mkg), then remove 8 mm bolt and washer.
