SUSPENSION
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 several times. Always release the bumper in
the down position. Set the front end alignment to
specifications while the vehicle is in its NOR­
MALLY LOADED CONDITION.
CAMBm
The wheel camber angle is preset and is not adjust­
able.
C A S T E R
Check the caster of the front axle for correct angle.
Be sure the axle is not bent or twisted. Road test the
vehicle and make left and right turn. Observe the
steering wheel return-to-center position. Low caster
will cause poor steering wheel returnability.
Caster can be adjusted by rotating the cams on the
lower suspension arm (Fig. 3). Refer to the Align­
ment Specification Chart for the correct setting.
TOE POSITION
The wheel toe position adjustment should be the fi­
nal adjustment.
(1) Start the engine and turn wheels both ways be­
fore straightening the wheels. Center and Secure the
steering wheel and turn off engine.
(2) Loosen the adjustment sleeve clamp bolts.
(3) Adjust the right wheel toe position with the
drag link (Fig. 4). Turn the sleeve until the right
wheel is at the correct TOE-IN position. Position
clamp bolts to their original position and tighten to
49 N-m (36 ft. lbs.) torque. Make sure the toe set­
ting does not change during clamp tightening.
(4) Adjust left wheel toe position with tie rod at
left knuckle. Turn the sleeve until the left wheel is at
the correct TOE-IN position. Position clamp bolts to
their original position and tighten to 27 N-m (20 ft.
Tbs.) torque. Make sure the toe setting does not
change during clamp tightening.
(5) Verify the right toe setting.
CAB-CHASSIS ALIGNMENT
To determine the correct caster alignment angle for
Cab-Chassis vehicles the following procedure must be
performed.
(1) Take a height measurement to the center of the
front gauge hole in the frame. Take another mean-
surement to the center of the rear spring hanger bolt
(Fig. 5). Take these measurements on both sides of
the vehicle.
