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).

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.

LOWER BALL JOINT
DIAGNOSIS AND TESTING - LOWER BALL
JOINT
To properly diagnose the lower ball joint two read-
ings from the dial indicator are necessary, The two
readings must be added together to find a total ball
joint movement as identified in the steps below.
(1) Raise and support the vehicle.
(2) Attach a dial indicator with the indicator rest-
ing on the flat part of the steering knuckle by the
lower ball stud (Fig. 11).
(3) Set the dial indicator to zero.
NOTE: Use care not to damage the upper ball joint
grease seal.
(4) Pry between the knuckle and the axle tube
yoke next to the upper ball joint, Record the reading
on the dial indicatorThis will be the first reading
(Fig. 12).
(5) Set the dial indicator back to zero.
(6) Set up a jackstand and use a long prybar to lift
the knuckle assembly (Fig. 13), pry upwards on the
flat part of the steering knuckle next to the ball joint
stud and nut (Fig. 14) using the jackstand as lever-
age. Record the reading on the dial indicatorThis
will be the second reading.(7) Add the two reading together for a total lower
ball joint movement, If this reading is above 2.29 mm
(0.090 in) then replacement of the lower ball joint is
necessary (Refer to 2 - SUSPENSION/FRONT/
LOWER BALL JOINT - REMOVAL).

DIAGNOSIS AND TESTING - UPPER BALL
JOINT
To properly diagnose the upper ball joint two read-
ings from the dial indicator are necessary, The two
readings must be added together to find a total ball
joint movement as identified in the steps below.
(1) Raise and support the vehicle.
(2) Attach a dial indicator with the indicator rest-
ing on either the front or back sides of the steering
knuckle as close to the upper ball joint as possible
(Fig. 18).
(3) Set the dial indicator to zero.
(4) Grab the tire by pushing in on the top of the
tire and pulling out on the bottom of the tire. Record
the reading on the dial indicatorThis will be the
first reading(Fig. 18).
(5) Set the dial indicator back to zero.
(6) Grab the tire by pulling in on the top of the
tire and pushing out on the bottom of the tire.
Record the reading on the dial indicatorThis will be
the second reading(Fig. 18).
(7) Add the two reading together for a total upper
ball joint movement, If this reading is above 1.52 mm
(0.060 in) then replacement of the upper ball joint is
necessary (Refer to 2 - SUSPENSION/FRONT/UP-
PER BALL JOINT - REMOVAL).
REMOVAL
(1) Position special tool 6761 (RECEIVER) and
8445±3 (DRIVER) with C-4212±F as shown to
remove upper ball stud (Fig. 19).
INSTALLATION
(1) Position special tool 8445±2 (DRIVER) and
8975±5 (RECEIVER) with C-42121±F as shown to
install upper ball stud (Fig. 20).

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.
