INSTALLATION
(1) Slide inner CV joint seal boot retaining clamp,
onto the interconnecting shaft. Then, slide the
replacement inner CV joint sealing boot onto the
interconnecting shaft.Inner CV joint seal boot
MUST be positioned on interconnecting shaft
so the raised bead on the inside of the small
diameter end of the seal boot is in mating
groove on interconnecting shaft (Fig. 18).(2) Install spider assembly onto interconnecting
shaft (Fig. 19). Spider assembly must be installed on
interconnecting shaft far enough to fully install spi-
der retaining snap-ring. If the spider assembly will
not fully install on interconnecting shaft by hand, it
can be installed by tapping the spider body with a
brass drift (Fig. 20).Do not hit the outer tripod
bearings in an attempt to install spider assem-
bly on interconnecting shaft.

CAUTION: Seal must not be dimpled, stretched or
out of shape in any way. If seal is NOT shaped cor-
rectly, equalize pressure in seal and shape it by
hand.
(9) Position sealing boot into the tripod housing
retaining groove. Install seal boot retaining clamp
evenly on sealing boot.
(10) Position trilobal boot to interface with the tri-
pod housing. The lobes of the boot must be properly
aligned with the recess's of the tripod housing.
CAUTION: The following positioning procedure
determines the correct air pressure inside the inner
CV joint assembly prior to clamping the sealing
boot to inner CV joint housing. If this procedure is
not done prior to clamping sealing boot to CV joint
housing sealing boot durability can be adversely
affected.
CAUTION: When venting the inner CV joint assem-
bly, use care so that the inner CV sealing boot does
not get punctured, or in any other way damaged. If
sealing boot is punctured, or damaged in any way
while being vented, the sealing boot can not be
used.(11) Insert a trim stick between the CV joint hous-
ing and the sealing boot insert to vent inner CV joint
assembly (Fig. 25).When inserting trim stick
between tripod housing and sealing boot
ensure trim stick is held flat and firmly against
the tripod housing. If this is not done damage
to the sealing boot can occur.
(12) With trim stick inserted between sealing boot
insert and the CV joint housing, position the inter-
connecting shaft so it is at the center of its travel in
the tripod joint housing. Remove the trim stick from
between the sealing boot insert and the CV joint
housing.This procedure will equalize the air
pressure in the CV joint, preventing premature
sealing boot failure.
(13) Clamp CV joint sealing boot to CV joint, using
required procedure for type of boot clamp application.
CRIMP TYPE BOOT CLAMP
If seal boot uses crimp type boot clamp, use the fol-
lowing procedure to install the retaining clamp.
(1) Place crimping tool C-4975-A over bridge of
clamp (Fig. 26).
(2) Tighten nut on crimping tool C-4975-A until
jaws on tool are closed completely together, face to
face (Fig. 27).

HALF SHAFT - REAR
DESCRIPTION
The inner and outer joints of both half shaft
assemblies are tripod joints. The tripod joints are
true constant velocity (CV) joint assemblies, which
allow for the changes in half shaft length through
the jounce and rebound travel of the rear suspension.
On vehicles equipped with ABS brakes, the outer
CV joint is equipped with a tone wheel used to deter-
mine vehicle speed for ABS brake operation.
The inner tripod joint of both half shafts is bolted
rear differential assembly's output flanges. The outer
CV joint has a stub shaft that is splined into the
wheel hub and retained by a steel hub nut.
DIAGNOSIS AND TESTING - HALF SHAFT
VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard
tripod joint and outboard CV joint; this is a sign of
inner or outer joint seal boot or seal boot clamp dam-
age.
(2) A light film of grease may appear on the right
inner tripod joint seal boot; this is considered normal
and should not require replacement of the seal boot.
NOISE AND/OR VIBRATION IN TURNS
A clicking noise and/or a vibration in turns could
be caused by one of the following conditions:
²Damaged outer CV or inner tripod joint seal
boot or seal boot clamps. This will result in the loss
and/or contamination of the joint grease, resulting in
inadequate lubrication of the joint.
²Noise may also be caused by another component
of the vehicle coming in contact with the half shafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a result of one of the following
conditions:²A torn seal boot on the inner or outer joint of the
half shaft assembly.
²A loose or missing clamp on the inner or outer
joint of the half shaft assembly.
²A damaged or worn half shaft CV joint.
SHUDDER OR VIBRATION DURING ACCELERATION
This problem could be a result of:
²A worn or damaged half shaft inner tripod joint.
²A sticking tripod joint spider assembly (inner tri-
pod joint only).
²Improper wheel alignment. (Refer to 2 - SUS-
PENSION/WHEEL ALIGNMENT - STANDARD
PROCEDURE)
VIBRATION AT HIGHWAY SPEEDS
This problem could be a result of:
²Foreign material (mud, etc.) packed on the back-
side of the wheel(s).
²Out of balance tires or wheels. (Refer to 22 -
TIRES/WHEELS - STANDARD PROCEDURE)
²Improper tire and/or wheel runout. (Refer to 22 -
TIRES/WHEELS - DIAGNOSIS AND TESTING)
REMOVAL
(1) Lift vehicle on hoist so that the wheels hang
freely.
(2) Remove rear wheel.
(3) Remove cotter pin, nut lock, and wave washer
(Fig. 1).
(4) Remove hub nut and washer.
CAUTION: The half shaft outer CV joint, when
installed, acts as a bolt and secures the hub/bear-
ing assembly. If the vehicle is to be supported or
moved on its wheels, install and torque a bolt
through the hub. This will ensure that the hub/bear-
ing assembly cannot loosen.
(5) Remove inner half shaft retaining bolts (Fig. 2).
