2002 JEEP LIBERTY wheel bolts

STANDARD PROCEDURE - CAMBER AND
CASTER ADJUSTMENT
Camber and caster angle adjustments involve
changing the position of the lower suspension arm
cam bolts. (Fig. 4)
STANDARD PROCEDURE - TOE ADJUSTMENT
4X4 SUSPENSION HEIGHT MESUREMENT MUST
BE PERFORMED BEFORE AN ALIGNMENT.
The wheel toe position adjustment is the final
adjustment.
(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.
NOTE: Each 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 as necessary (Fig. 5).
(4)
Tighten the tie rod jam nut to 75 N´m (55 ft. lbs.).
(5) Verify the specifications
(6) Turn off engine.
STANDARD PROCEDURE - CAMBER, CASTER
AND TOE ADJUSTMENT
Camber and caster angle adjustments involve
changing the position of the lower suspension arm
cam bolts. (Fig. 4)
CASTER
Moving the rear position of the cam bolt 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 cam bolt
in or out. Then move the front of the cam bolt
slightly in the opposite direction. (Fig. 4)
To increase positive caster angle, move the rear posi-
tion of the cam bolt outward (from the engine). Move
the front of cam bolt inward (toward the engine) slightly
until the original camber angle is obtained. (Fig. 4)
CAMBER
Move both of the cam bolts together in or out. This
will change the camber angle significantly and caster
angle slightly. (Fig. 4)
After adjustment is made tighten the cam bolt nuts
to proper torque specification.
TOE ADJUSTMENT
The wheel toe position adjustment is the final
adjustment.
(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.
NOTE: Each 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 as necessary (Fig. 5).
(4)
Tighten the tie rod jam nut to 75 N´m (55 ft. lbs.).
(5) Verify the specifications
(6) Turn off engine.

LOWER BALL JOINT
DIAGNOSIS AND TESTING - LOWER BALL
JOINT
(1) Raise the vehicle on a drive-on hoist.
NOTE: If a drive-on hoist is not available, use
wooden blocks with jack stands to support the
lower control arm in the ball joint area. Place the
jack stands appropriately and lower the hoist plac-
ing weight on the lower control arm. The lower con-
trol arms should now be supporting the vehicle
weight.
(2) With the use of jack stands, lift the front end
off the hoist and position wooden blocks underneath
both lower control arms supporting the vehicles
weight.
(3) Remove the tire and wheel assembly.
(4) Attach a dial indicator to the base of the lower
control arm and align the dial indicator's contact
point with the direction of the stud axis, touch the
machined flat on the knuckle and zero the dial indi-
cator. (Fig. 2)
NOTE: Use care when applying the load to the
knuckle, so the parts are not damaged using care
not to tear the boot.
(5) From the front of the vehicle, insert a pry bar
to get it rested on the lower control arm and use
lever principle to push the knuckle up until the arm
of the dial indicator no longer moves.(6) Record the ball joint movement on each side of
the vehicle. The end play is acceptable with no more
than 1.5mm of end play back to back.LOWER CONTROL ARM
