ALIGNMENT MEASUREMENTS AND
ADJUSTMENTS
Before each alignment reading the vehicle should be
jounced (rear first, then front) . Grasp each bumper at
the center and jounce the vehicle up and down three
times. Always release the bumper in the down position .
CAMBER
The wheel camber angle is preset . This angle is not
adjustable and cannot be altered.
CASTER
Check the caster of the front axle for correct angle .
Be sure the axle is not bent or twisted. Road test the
vehicle and observe the steering wheel return-to-cen-
ter position . Low caster will cause poor steering
wheel returnability.
During the road test, turn the vehicle to both the left
and right. If the steering wheel returns to the center
position unassisted, the caster angle is correct. How-
ever, if steering wheel does not return toward the center
position unassisted, a low caster angle is probable .
Caster can be adjusted by loosening and rotating the
cams on the lower suspension arm (Fig. 1) . Changing
caster angle will also change the front propeller
shaft angle. The propeller shaft angle has priority
over caster. Refer to Group 3, Differential and
Driveline for additional information.
