(6) Proceed with Camber And Caster Angle.
CAMBER AND CASTER ANGLE
Camber and caster angles on this vehicle are
adjustable using cams located on the lower control
arm bushing pivot bolts. Both front and rear camber
and caster are adjustable on this vehicle. Camber
readings are viewed on the wheel alignment equip-
ment, but caster readings are viewed on the DRBIII
t
scan tool as described in INCLINOMETER SETUP
FOR CASTER ANGLE VIEWING.
CAUTION: Prior to any cam bolt rotation, cam bolt
lock nuts must be loosened, allowing lower control
arm mounting brackets to spread, thus allowing
free movement of control arm bushings. If not per-
formed, serious bracket bending, weld breakage of
cam retainer, free cam and cam bolt shank fractur-
ing, or thread damage can occur. It may be neces-
sary to tap bracket ears away from bushings to
allow unrestricted cam bolt movement.
CAMBER ANGLE
Camber angle adjustment involves the reposition-
ing of the lower control arm pivot bolts using the
adjustment cams (Fig. 14). There are 2 cams located
on each lower control arm pivot bolt, 4 per each cor-
ner of the vehicle front and rear (Fig. 14). Reposition-
ing of the pivot bolt cams in the same direction
moves the lower ball joint in or out to obtain the
required camber specifications.
CASTER ANGLE
Caster angle adjustment, like camber angle adjust-
ment, involves the repositioning of the lower control
arm pivot bolts using the adjustment cams. There
are 2 cams located on each lower control arm pivot
bolt, 4 per each corner of the vehicle front and rear
(Fig. 14). Repositioning of the pivot bolt cams in
opposite directions moves the lower ball joint fore or
aft as required to obtain the required caster specifi-
cations.
