Jeep Grand Cherokee WK. Manual — part 10
STANDARD PROCEDURE
CAMBER, CASTER AND TOE ADJUSTMENT
NOTE: SUSPENSION HEIGHT MEASUREMENT MUST BE PERFORMED BEFORE AN ALIGNMENT.
Camber and caster angle adjustments involve changing the position of the lower control arm with the slots in the
frame brackets to move the lower control arm inwards or outwards for proper adjustment. This can be achieved by
using a long pry bar with a curved tip and inserting the pry bar into the lower control arm frame brackets
and prying inwards or outwards.
NOTE: Camber and caster adjustments must be made at the lower control arm Do not use the upper control
arm for Camber and Caster adjustments.
NOTE: When the lower control arm pivot bolts are loosened the lower control arm will normally go outwards
automatically with the weight of the vehicle.
CASTER
Moving the rear position of the lower control arm at the frame in or out, will change the caster angle significantly
and camber angle only slightly. To maintain the camber angle while adjusting caster, move the rear of the lower
control arm in or out. Then move the front of the lower control arm slightly in the opposite direction.
CAMBER
Move both the front and rear of the lower control arm together in or out. This will change the camber angle signif-
icantly and caster angle slightly.
After adjustment is made tighten the lower control arm bolt & nuts to FRONT169 N·m (125 ft. lbs.) and the REAR
88 N·m (65 ft. lbs.).
TOE ADJUSTMENT
The wheel toe position adjustment is the final adjust-
ment.
1. Start the engine and turn wheels both ways before
straightening the wheels. Secure the steering
wheel with the front wheels in the straight-ahead
position.
2. Loosen the tie rod jam nuts (3).
NOTE: Each front wheel should be adjusted for
one-half of the total toe position specification.
This will ensure the steering wheel will be cen-
tered when the wheels are positioned straight-
ahead.
3. Adjust the wheel toe position by turning the inner
tie rod (4) as necessary.
4. Tighten the tie rod jam nut (3) to 75N·m (55 ft. lbs.).
5. Verify the specifications.
6. Turn off engine.

DESCRIPTION
NOTE: Suspension components with rubber/urethane bushings should be tightened with the vehicle at nor-
mal ride height. It is important to have the springs supporting the weight of the vehicle when the fasteners
are torqued. If springs are not at their normal ride position, vehicle ride comfort could be affected and pre-
mature bushing wear may occur.
The front suspension is designed to allow each wheel to adapt to different road surfaces independently. The wheels
are mounted to hub bearings on the steering knuckle spindles. The double-row hub bearings are sealed and lubri-
cated for life. The steering knuckles turn (pivot) on ball joints integral to the outboard portion of the upper control
arms and pressed into the lower steering knuckle. The ball joints are lubricated for life.
