Chrysler RG Voyager. Manual — part 643

(11) If toe readings obtained are not within the

required specification range, adjust toe to meet the
preferred specification setting. Toe is adjustable
using the following procedure.

TOE

(1) Center the steering wheel and lock in place

using a steering wheel clamp.

CAUTION: Do not twist front inner tie rod to steer-
ing gear rubber boots during front wheel Toe
adjustment.

(2) Loosen front inner to outer tie rod end jam

nuts (Fig. 12). Grasp inner tie rods at serrations and
rotate inner tie rods of steering gear (Fig. 12) to set
front toe to the preferred toe specification. (Refer to 2
- SUSPENSION/WHEEL ALIGNMENT - SPECIFI-
CATIONS)

(3) Tighten tie rod jam nuts (Fig. 12) to 75 N·m

(55 ft. lbs.) torque.

(4) Adjust steering gear to tie rod boots at the

inner tie rod.

(5) Remove steering wheel clamp.
(6) Remove the alignment equipment.
(7) Road test the vehicle to verify the steering

wheel is straight and the vehicle does not wander or
pull.

STANDARD PROCEDURE - CURB HEIGHT
MEASUREMENT

The wheel alignment is to be checked and all align-

ment adjustments made with the vehicle at its
required curb height specification.

Vehicle height is to be checked with the vehicle on

a flat, level surface, preferably a vehicle alignment
rack. The tires are to be inflated to the recommended
pressure. All tires are to be the same size as stan-
dard equipment. Vehicle height is checked with the
fuel tank full of fuel, and no passenger or luggage
compartment load.

Vehicle height is not adjustable. If the measure-

ment is not within specifications, inspect the vehicle
for bent or weak suspension components. Compare
the parts tag on the suspect coil spring(s) to the
parts book and the vehicle sales code, checking for a
match. Once removed from the vehicle, compare the
coil spring height to a correct new or known good coil
spring. The heights should vary if the suspect spring
is weak.

(1) Measure from the inboard edge of the wheel

opening fender lip directly above the wheel center
(spindle), to the floor or alignment rack surface.

(2) When measuring, the maximum left-to-right

differential is not to exceed 12.5 mm (0.5 in.).

(3) Compare the measurements to the specifica-

tions listed in the following Curb Height Specifica-
tions charts.

HALF SHAFT - FRONT

DESCRIPTION

All vehicles use an unequal length half shaft sys-

tem (Fig. 1).

The left half shaft uses a tuned rubber damper

weight. When replacing the left half shaft, be sure
the replacement half shaft has the same damper
weight as the original.

All half shaft assemblies use the same type of

inner and outer joints. The inner joint of both half
shaft assemblies is a tripod joint, and the outer joint
of both half shaft assemblies is a Rzeppa joint. Both
tripod joints and Rzeppa joints are true constant
velocity (CV) joint assemblies. The inner tripod joint
allows for the changes in half shaft length through
the jounce and rebound travel of the front suspen-
sion.

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 splined

into the transaxle side gears. The inner tripod joints
are retained in the side gears of the transaxle using
a snap ring located in the stub shaft of the tripod
joint. 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.

3 - 1

• 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) Raise vehicle.
(2) Remove the cotter pin, nut lock (Fig. 2) and

wave washer (Fig. 3) from the end of the half shaft.

(3) Remove the wheel and tire assembly from the

vehicle. (Refer to 22 - TIRES/WHEELS - REMOVAL)

CAUTION: The halfshaft 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 while the halfshaft is removed, it is neces-

sary to install and properly torque a bolt through
the hub. This will ensure that the hub/bearing
assembly will not loosen.
