DISASSEMBLY
(1) Remove propeller shaft.
(2) Mark propeller shaft, link yoke and flange yoke
for assembly reference.
(3) Tap outside of the bearing cap assembly with
drift to loosen snap rings.
(4) Remove all bearing cap snap rings (Fig. 39).
(5) Remove grease fittings if equipped.
(6) Position a socket on the press with an inside
diameter large enough to receive the bearing cap
under the link yoke.
(7) Place another socket with an outside diameter
smaller than the bearing cap on the upper bearing
cap.(8) Press one bearing cap from outboard side of the
link yoke, enough to grasp the cap with vise jaws
(Fig. 40).
(9) Grasp protruding bearing cap with vise jaws
and tap link yoke with a mallet to remove bearing
cap (Fig. 41).

(10) Flip assembly and repeat Step 6, Step 7, Step
8 and Step 9 to remove the opposite bearing cap.
(11) Remove cross centering kit assembly and
spring (Fig. 42).
(12) Press remaining bearing caps out the other
end of the link yoke.
ASSEMBLY
CAUTION: All alignment marks on the link yoke and
propeller shaft yoke must be aligned during assem-
bled.
(1) Apply (EP) N.L.G.I. Grade 1 or 2 grease to
inside of yoke bores.
(2) Fit cross into the propeller shaft yoke (Fig. 43).(3) Place bearing cap over the trunnion and align
cap with the yoke bore (Fig. 44). Keep needle bear-
ings upright in the bearing cap.
(4) Press bearing cap into yoke bore enough to
clear snap ring groove and install snap-ring (Fig. 45).

(5) Flip propeller shaft yoke and install other bear-
ing cap onto the opposite trunnion and install a snap
ring (Fig. 46).
(6) Fit link yoke onto remaining trunnions and
press both bearing caps into place and install snap
rings (Fig. 47).(7) Install centering kit assembly inside the link
yoke (Fig. 48).
NOTE: Verify spring is properly positioned.
(8) Place two bearing caps on opposite trunnions of

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.
