(8) Position outer C/V joint sealing boot into its

retaining groove on outer C/V joint housing. Install
sealing boot to outer C/V joint retaining clamp evenly
on sealing boot.

(9) Clamp sealing boot onto outer C/V joint hous-

ing using Crimper, Special Tool C-4975-A and the fol-
lowing procedure. Place crimping tool C-4975-A over
bridge of clamp (Fig. 35). Tighten nut on crimping
tool C-4975-A until jaws on tool are closed completely
together, face to face (Fig. 36).

(10) Install the halfshaft requiring boot replace-

ment back on the vehicle. (Refer to 3 - DIFFEREN-

HALF SHAFT - REAR

DESCRIPTION

The inner joints of both half shaft assemblies are

tripod joints. The outer joints of both assemblies are
Rzeppa 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.

The inner tripod joint of both half shafts is splined

into the rear differential assembly and retained by a
snap ring. 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 tri-

pod joint and outboard CV joint; this is a sign of inner
or outer joint seal boot or seal boot clamp damage.

NOISE AND/OR VIBRATION IN TURNS

A clicking noise and/or a vibration in turns could

be caused by one of the following conditions:

• Damaged 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.

• Noise 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:

• A torn seal boot on the inner or outer joint of the

half shaft assembly.

• A loose or missing clamp on the inner or outer

joint of the half shaft assembly.

• A damaged or worn half shaft CV joint.

CLICKING/POPPING NOISE DURING SHIFT (R-to-D
or D-to-R)

This noise may be caused by a lack of lubrication

at halfshaft-to-hub splines and abutment face.

SHUDDER OR VIBRATION DURING ACCELERATION

This problem could be a result of:
• A worn or damaged half shaft inner tripod joint.

• A sticking tripod joint spider assembly (inner tri-

pod joint only).

• Improper wheel alignment. (Refer to 2 - SUS-

PENSION/WHEEL

ALIGNMENT

STANDARD

PROCEDURE)

VIBRATION AT HIGHWAY SPEEDS

This problem could be a result of:
• Foreign material (mud, etc.) packed on the back-

side of the wheel(s).

• Out of balance tires or wheels. (Refer to 22 -

TIRES/WHEELS - STANDARD PROCEDURE)

• Improper tire and/or wheel runout. (Refer to 22 -

TIRES/WHEELS - DIAGNOSIS AND TESTING)

REMOVAL

NOTE:

Rear

suspension

and

drivetrain

design

require this procedure to be performed on a “drive-
on” hoist, as the front and rear suspension needs
to be compressed to ride height to facilitate rear
halfshaft removal.

(1) Place vehicle on drive-on hoist in Park.
(2) Remove rear wheel center cap.
(3) Remove cotter pin, nut lock, and spring washer

(Fig. 1).

(4) Remove hub nut and washer.
(5) Raise vehicle on hoist.
(6) Remove exhaust system center hanger (at pro-

peller shaft bearing/support).

(7) Disconnect exhaust system at rear-most hanger

and lower.

HALF SHAFT - REAR

(8) Lower exhaust system at least 254 mm (10 in.).

Support system with suitable wire or rope.

(9) Index propeller shaft and rear driveline module

flanges using paint mark, chalk, etc. for installation
reference.

(10) Remove three (3) propeller shaft-to-driveline

module bolts. Do not attempt to disconnect shaft
from module, as it will be disconnected upon lower-
ing driveline module.

(11) Support driveline module with transmission

jack (or equivalent) (Fig. 2).

(12) Using suitable screwdriver, partially dislodge

halfshaft (side being removed) from differential.

Install Tool 9099 to protect seal upon disassembly
(Fig. 3).

(13) Remove three (3) rear driveline module-to-

crossmember bolts (Fig. 4) (Fig. 5).

(14) Lower driveline module assembly just enough

to facilitate removal of shaft from differential. Make
sure Tool 9099 engages seal.

(15) Disconnect propeller shaft from driveline mod-

ule and secure to exhaust system (Fig. 6).

CAUTION: Do not allow the propeller shaft to hang
from the vehicle unsupported. Damage may occur
to the joint, boot, and center bearing from over-an-
gulation.

(16) Remove halfshaft from hub/bearing assembly.

INSTALLATION

(1) Install

halfshaft

hub/bearing

assembly.

Install hub nut and washer but do not tighten at this
time.

(2) Using Tool 9099, install halfshaft to differential

assembly (Fig. 7).

(3) Index and install propeller shaft to driveline

module flange. Install, but do not tighten, three (3)
propeller shaft-to-driveline module bolts.

(4) Raise driveline module into position. Install

and torque module-to-cradle bolts to 102 N·m (75 ft.
lbs.) (Fig. 8) (Fig. 9).

(5) Torque propeller shaft-to-driveline module bolts

to 54 N·m (40 ft.lbs.)
