CAMBER & CASTER
Caster and camber adjustments are provided for by shims on the upper control arm. Shims are to be added, subtracted or switched from the front and rear
legs, as necessary, to achieve desired settings. To adjust camber, remove or add an equal number of shims to the front and rear legs of the control arm.
To adjust caster, transfer shims between the front and rear legs of the control arm as required to achieve desired settings. If an unequal number of shims
is added or subtracted to the front or rear legs of the upper control arm, both caster and camber settings will be revised. Refer to the Caster/Camber
Variation Chart, Fig. 1, when adjusting camber and caster to specification.
