Fig. 1 Caster & camber adjustment
CASTER & CAMBER, ADJUST
Before checking and adjusting caster and camber angles, jounce front bumper at least three times, then allow vehicle to return to normal
height to prevent false readings..
Caster and camber adjustments are made by shims inserted between upper control arm shaft and frame bracket, Fig. 1. Add, subtract or transfer shims
as noted below.
To adjust caster and/or camber, loosen upper control arm shaft-to-frame nuts, then add or subtract shims as necessary and retorque nuts to 66 ft. lbs.
After adjustment, the shim pack should have at least two threads of bolt exposed beyond the nut. The difference between front and rear shim packs must
not exceed .040 inch.
When adjusting caster, transfer shims from front to rear or rear to front. The transfer of one shim from rear to front bolt will decrease positive caster.
When adjusting camber, change shims equally at both front and rear of shaft. Adding an equal number of shims at front and rear will decrease positive
camber.
When performing either caster or camber adjustment, always tighten nut on thinner shim pack first to improve shaft-to-frame clamping force and
torque retention.
