2002 JEEP LIBERTY Rear lower control arm

STANDARD PROCEDURE
STANDARD PROCEDURE - HEIGHT
MEASUREMENT
RIDE HEIGHT
NOTE: The suspension is non-adjustable.
The vehicle suspension height should be measured
before performing wheel alignment procedure. Also
when front suspension components have been
replaced. This measure must be performed with the
vehicle supporting it's own weight and taken on both
sides of the vehicle.
Front and rear ride heights are not adjustable. The
spring selections at assembly determine ride height
for acceptable appearance of the vehicle. Ride height
dimensions assume full fluids (including fuel) and
zero passengers. Refer to the table below for front
ride height dimensions.
Vehicle ride height audits should be performed uti-
lizing the following procedure:
(1) Drive the vehicle straight and forward on a
non-tacky surface for a minimum of 20 feet to neu-
tralize track width.
(2) Bounce the front of the vehicle five times.
(3) Measure and record the dimensions
FRONT RIDE HEIGHT Front ride height is
defined by the relative vertical distance between the
spindle center line and the rear pivot point of the
front lower control arm to cradle attachment. The
spindle center line is to be measured at the outer
wheel face (point A). The rear pivot point is to be
measured at the center of the cam bolt (point B) at
its rearward most end (nut end). (Fig. 2)REAR RIDE HEIGHT Rear ride height is defined
by the relative vertical distance between the top of
the lower spring seat strike surface and the bottom
of the jounce cup (true metal to metal jounce travel).
This is to be measured vertically inside the coil from
the point intersecting the inboard edge and the for/
aft center of the jounce cup (point C) down to the
strike surface (point D). (Fig. 3)

WHEEL ALIGNMENT (Continued)

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

DESCRIPTION
The rear suspension (Fig. 1) is comprised of :
²Drive axle
²Shock absorbers
²Coil springs
²Lower suspension arms
²Upper suspension arm
²Stabilizer bar
CAUTION: Suspension components with rubber/ure-
thane bushings should be tightened with the vehi-
cle at normal ride height. It is important to have the
springs supporting the weight of the vehicle when
the fasteners are torqued. This will maintain vehicle
ride comfort and prevent premature bushing wear.
WARNING
WARNING:: Suspension components with rubber
bushings must 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 fas-
teners are torqued. If springs are not at their normal
ride position, vehicle ride comfort will be affected
and cause premature bushing wear.

UPPER BALL JOINT
REMOVAL
(1) Raise and support the vehicle.
(2) Support the rear axle with a hydraulic jack.
(3) Remove the ball joint pinch bolt from the top of
the axle. (Fig. 7)
(4) Seperate the ball joint arm assembly from the
differential housing by prying upwards.
INSTALLATION
(1)Raise the rear axle with a hydraulic jack to align
the ball joint with the differential housing bracket.
(2) Insert the ball joint into the differential hous-
ing bracket.
(3) Install the ball joint pinch bolt and tighten to
95 N´m (70 ft. lbs.). (Fig. 7).
(4) Remove the supports and lower the vehicle.
UPPER CONTROL ARM
DESCRIPTION - UPPER SUSPENSION ARM,
BUSHINGS, AND BALL JOINT
The suspension arm uses vertical spool bushings to
isolate road noise. The suspension arm is bolted
through bushings to cage nuts in the body and a ball
joint to the top of the differential housing.
OPERATION - UPPER SUSPENSION ARM,
BUSHINGS, AND BALL JOINT
The upper suspension arm provides fore/aft and
lateral location of the rear axle. The suspension arm
travel is limited through the use of jounce bumpers
in compression and shock absorbers in rebound.
REMOVAL
(1) Raise and support the vehicle.
(2) Support the rear axle with a hydraulic jack.
(3) Remove the ball joint pinch bolt from the top of
the differential housing bracket (Fig. 7).
(4) Remove partial nuts from the heat shield in
order to lower the shield down enough to get the
proper clearence to remove the right side bolt from
the body.
(5) Remove the upper suspension arm mounting
bolts from the body and remove the arm (Fig. 8).
(6) Remove the support bracket mounting bolts if
needed. (Fig. 9)
