(Figure 1) Caster & camber adjustment. 4 x 2 models
Caster and camber adjustments are made by shims inserted between upper control arm shaft and frame bracket, Fig. 1. Add, subtract, or transfer shims
to change readings 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 torque upper control arm
shaft to frame nuts to 45 ft. lbs.
Caster, Adjust
Transfer shims from front to rear, or rear to front. The transfer of one shim from rear to front bolt will decrease positive caster.
Camber, Adjust
Change shims at both front and rear of shaft.. Adding an equal amount of shims at both front and rear locations will decrease positive camber.
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 0.40 inches.
