UPPER BALL JOINT
DIAGNOSIS AND TESTING - UPPER BALL
JOINT
NOTE: If the ball joint is equipped with a lubrication
fitting, grease the joint then road test the vehicle
before performing test.
(1) Raise the front of the vehicle. Place safety floor
stands under both lower control arms as far outboard
as possible. Lower the vehicle to allow the stands to
support some or all of the vehicle weight.
(2) Remove the front tires.(3) Mount a dial indicator solidly to the frame and
then zero the dial indicator.
(4) Position dial indicator plunger on the topside of
the upper ball joint (Fig. 32).
NOTE: The dial indicator plunger must be perpen-
dicular to the machined surface of the ball joint
(Fig. 32).
NOTE: Use care not to pry or tear the ball joint
boot, when checking the free play.
(5) Position a pry bar between the steering
knuckle and the upper control arm. Pry upwards on
the upper control arm (Fig. 32).
(6) If the travel exceeds 0.5 mm (0.020 in.), replace
the upper control arm since the upper ball joint is
integral to the arm (Refer to 2 - SUSPENSION/
FRONT/UPPER CONTROL ARM - REMOVAL).
(7) If the upper ball joint is within specs reinstall
the front tires (Refer to 22 - TIRES/WHEELS/
WHEELS - STANDARD PROCEDURE).

(1) Remove rear propeller shaft.
(2) Mark the two shafts (Fig. 16) for installation
reference.(3) Remove slip joint boot clamp and separate the
two shafts.
(4) Use hammer and punch to tap slinger away
from shaft to provide room for bearing splitter.
(5) Position Bearing Splitter Tool 1130 between
slinger and shaft.
CAUTION: Do not damage shaft spline during
removal of center bearing.
(6) Set shaft in press and press bearing off the
shaft.
INSTALLATION
NOTE: Two types of center bearings are used and
are not interchangeable. Install the same type as
the vehicle was built with.
(1) Install new slinger on shaft and drive into posi-
tion with appropriate installer tool.
(2) Install new center bearing on shaft with Bear-
ing Installer Tool 6052. Drive on shaft with hammer
until bearing is seated.
(3) Clean shaft splines and apply a coat of multi-
purpose grease.
(4) Align master splines and slide front and rear
half-shafts together. Reposition slip yoke boot and
install new clamp.
(5) Install propeller shaft in vehicle.
ADJUSTMENTS
CENTER BEARING
Launch shudder is a vibration that occurs at first
acceleration from a stop. Shudder vibration usually
peaks at the engines highest torque output. Shudder
is a symptom associated with vehicles using a two-
piece propeller shaft. To decrease shudder, lower the
center bearing in 1/8 inch increments. Use shim
stock or fabricated plates. Plate stock must be used
to maintain compression of the rubber insulator
around the bearing. Do not use washers. Replace the
original bolts with the appropriate increased length
bolts.

HALF SHAFT
CAUTION
CAUTION:: Never grasp half shaft assembly by the
boots. This may cause the boot to pucker or crease
and reduce the service life of the boot.
Avoid over angulating or stroking the C/V joints
when handling the half shaft.
Half shafts exposed to battery acid, transmission
fluid, brake fluid, differential fluid or gasoline may
cause the boots to deteriorate. Failure to heed cau-
tion may result in damage.
DIAGNOSIS AND TESTING
Check inboard and outboard C/V joint for leaking
grease. This is a sign of boot or boot clamp damage.
NOISE/VIBRATION IN TURNS
A clicking noise or vibration in turns could be
caused by a damaged outer C/V or inner tripod joint
seal boot or seal boot clamps. This will result in the
loss/contamination of the joint grease, resulting in
inadequate lubrication of the joint. Noise could also
be caused by another component of the vehicle com-
ing in contact with the half shafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a damaged or worn C/V joint. A
torn boot or loose/missing clamp on the inner/outer
joint which has allowed the grease to be lost will
damage the C/V joint.
SHUDDER/VIBRATION DURING ACCELERATION
This could be a worn/damaged inner tripod joint or
a sticking tripod joint. Improper wheel alignment
may also cause a shudder or vibration.
VIBRATION AT HIGHWAY SPEEDS
This problem could be a result of out of balance
front tires or tire/wheel runout. Foreign material
(mud, etc.) packed on the backside of the wheel(s)
will also cause a vibration.
REMOVAL
(1) With vehicle in neutral, position vehicle on
hoist.
(2) Remove half shaft hub nut.
(3) Remove brake caliper and rotor.
(4) Position hydraulic jack under lower suspension
arm and raise jack to unload rebound bumper.
(5) Remove lower shock absorber bolt.
(6) Remove upper ball joint nut and seperate ball
with Remover 8677 (Fig. 1).
(7) Disengage inner C/V joint from axle shaft with
two pry bars between the C/V housing and axle hous-
ing.
