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.

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.

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

(1) Lift vehicle on hoist so that the wheels hang

freely.

(2) Remove rear wheel.
(3) Remove cotter pin, nut lock, and spring 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).

(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 spring 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.).
