ALIGNMENT AND ADJUSTMENTS IFS
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 i n
the down position. Set the front end alignment to
specifications while the vehicle is in its NOR­
MALLY L O A D E D CONDITION.
CAMBER AND CASTER ADJUSTMENT
Camber and caster angle adjustments involve
changing the position of the upper suspension arm
pivot bar (Fig. 7). Refer to the Alignment Specifica­
tion Chart for the correct setting.
CASTER: Move only the rear position of the pivot
bar i n or out. This will change the caster angle sig­
nificantly and camber angle only slightly. To retain
the camber while adjusting caster, move the rear
pivot bar in or out. Move the forward pivot very
slightly i n the opposite direction.
For example, to increase a positive caster an­
gle, move the rear position of the pivot bar in­
ward (toward the engine). Move the front of
pivot bar outward (away from the engine)
slightly until the original camber angle is ob­
tained.

CAMBER: Move only the forward position of the
pivot bar i n or out. This will change the camber an­
gle significantly and caster angle only slightly. The
camber angle should be adjusted as close as possible
to the service reset specification.
• After adjustment is made tighten the pivot bar
nuts to 210 N-m (155 ft. lbs.) torque.
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. Secure the steering
wheel with the front wheels i n the straight-ahead po­
sition and turn off engine.
(2) Loosen the tie rod adjustment sleeve clamp
bolts/nuts.
E a c h front wheel should be adjusted for one-
half of the total toe position specification. This
will ensure the steering wheel will be centered
when the wheels are positioned straight-ahead.
(3) Adjust the wheel toe position by turning the tie
rod adjustment sleeves as necessary.
