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).
3 - 16 HALF SHAFT - REARRS

(6) The half shaft is spring loaded. Compress inner
half shaft joint slightly and pull downward to clear
rear differential output flange. Then pull half shaft
assembly outward to remove (Fig. 3).
INSTALLATION
(1) Install the outer CV joint stub shaft through
the hub bearing (Fig. 4).
(2) The half shaft is spring loaded. Compress inner
half shaft joint slightly and push upward until the
inner CV joint flange engages the rear differential
output flange.(3) Install the inner half shaft retaining bolts (Fig.
5). Torque the bolts to 61 N´m (45 ft.lbs.).
(4) Install the half shaft washer and hub nut.
Torque the hub nut to 244 N´m (180 ft.lbs.).
(5) Install the wave washer, nut lock, and a new
cotter pin (Fig. 6). Be sure to wrap the cotter pin
prongs tightly around the hub nut lock.
(6) Install rear wheel. Torque the lug nuts to 135
N´m (100 ft.lbs.).

(2) Clamp the half shaft into a suitable vise with
protective jaws clamped onto the interconnecting
shaft (Fig. 7).
(3) Remove the large and small diameter retaining
clamps holding the CV boot to the CV joint and the
interconnecting shaft (Fig. 8).
(4) Pull the boot back from the CV joint (Fig. 9).
(5) Remove the CV housing from the interconnect-
ing shaft and tripod assembly (Fig. 10).
(6) Remove the snap-ring holding the tripod
assembly onto the interconnecting shaft (Fig. 11).

LATCHING TYPE BOOT CLAMP
If seal boot uses low profile latching type boot
clamp, use the following procedure to install the
retaining clamp.
(1) Place prongs of clamp locking tool in the holes
of the clamp (Fig. 23).
(2) Squeeze tool together until top band of clamp is
latched behind the two tabs on lower band of clamp
(Fig. 24).
(3) Install the half shaft into the vehicle. (Refer to

adjustment, maintenance or fluid checks required
during the life of the unit.
The overrunning clutch allows the rear wheels to
overrun the front wheels during a rapid front wheel
lock braking maneuver. The overrunning action pre-
vents any feed-back of front wheel braking torque to
the rear wheels. It also allows the braking system to
control the braking behavior as a two wheel drive
(2WD) vehicle.
The overrunning clutch housing has a separate oil
sump and is filled independently from the differen-
tial. The fill plug is located on the side of the over-
running clutch case. When filling the overrunning
clutch with lubricant use MopartATF+4 (Automatic
Transmission FluidÐType 9602) or equivalent.
The differential assembly contains a conventional
open differential with hypoid ring gear and pinion
gear set. The hypoid gears are lubricated by SAE
80W-90 gear lubricant.DIAGNOSIS AND TESTING - REAR DRIVELINE
MODULE NOISE
Different sources can be the cause of noise that the
rear driveline module assembly is suspected of mak-
ing. Refer to the following causes for noise diagnosis.
DRIVELINE MODULE ASSEMBLY NOISE
The most important part of driveline module ser-
vice is properly identifying the cause of failures and
noise complaints. The cause of most driveline module
failures is relatively easy to identify. The cause of
driveline module noise is more difficult to identify.
If vehicle noise becomes intolerable, an effort
should be made to isolate the noise. Many noises that
are reported as coming from the driveline module
may actually originate at other sources. For example:
