maintenance CHRYSLER VOYAGER 2002 Owner's Manual

OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the tire and wheel
assembly (and driveshaft on All-Wheel-Drive vehi-
cles). The five wheel mounting studs mount the tire
and wheel assembly, and disc brake rotor or brake
drum to the vehicle.
On All-Wheel-Drive vehicles, the splined mating of
the driveshaft stub axle and hub allows the drive-
shaft to rotate with the hub and wheel.
Front-Wheel-Drive vehicles equipped with antilock
brakes have a wheel speed sensor and tone wheel
mounted to the rear of the hub and bearing. The tone
wheel rotates with the hub which is sensed by the
wheel speed sensor.
DIAGNOSIS AND TESTING - HUB AND
BEARING
The bearing contained in the hub and bearing
assembly will produce noise and vibration when worn
or damaged. The noise will generally change when
the bearings are loaded. A road test of the vehicle is
normally required to determine the location of a
worn or damaged bearing.
Find a smooth level road surface and bring the
vehicle up to a constant speed. When vehicle is at a
constant speed, swerve the vehicle back and forth
from the left and to the right. This will load and
unload the bearings and change the noise level.
When bearing damage is slight, the noise is some-
times noticeable at lower speeds and at other times
is more noticeable at speeds above 105 km/h (65
mph).

SHOCK ABSORBER
DESCRIPTION
There is one shock absorber on each side of the
rear suspension. The top of each shock absorber is
bolted to the frame rail. The bottom of each shock
absorber is bolted to the rear axle.
This vehicle is available with either standard type
or load-leveling shock absorbers. On the exterior,
load-leveling shock absorbers are larger in diameter
than standard shock absorbers. The load-leveling
shock absorbers mount the same as the standard
shock absorbers.
OPERATION
The shock absorber dampens jounce and rebound
motions of the spring and suspension.
Each load-leveling shock absorber is a self-leveling,
self-contained vehicle leveling system and shock
absorber combined. It does not require an external
compressor, hoses, or height leveling sensors. All the
height leveling sensors, hydraulic pump, etc., are con-
tained inside the shock absorber. It uses road inputs
(bumps, stops, starts, turns, acceleration, deceleration,
etc.) to activate pumping, which results in the exten-
sion and compression of the shock absorber.
REMOVAL - SHOCK ABSORBER
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Support the rear axle of the vehicle using 2
jackstands positioned at the outer ends of the axle.

STABILIZER BAR
DESCRIPTION
Front-wheel-drive models use a stabilizer bar that
is mounted behind the rear axle. All-wheel-drive
models use a stabilizer bar that is mounted in front
of the rear axle.The stabilizer bar interconnects both sides of the
rear axle and attaches to the rear frame rails using 2
rubber isolated link arms.
Both type stabilizer bars have the same basic com-
ponents. Attachment to the rear axle tube, and rear
frame rails is through rubber-isolated bushings.
The 2 rubber isolated links are connected to the
rear frame rails by brackets. These brackets are
bolted to the bottom of the frame rails.
OPERATION
Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
to reduce body roll.

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
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:

BRAKE LINES
DESCRIPTION - BRAKE TUBES AND HOSES
The brake tubes are steel with a corrosion-resis-
tant nylon coating applied to the external surfaces.
The flex hoses are made of reinforced rubber with fit-
tings at each end.
The primary and secondary brake tubes leading
from the master cylinder to the ABS ICU Hydraulic
Control Unit (HCU) or the non-ABS junction block
have a special flexible section. This flexible section is
required due to cradle movement while the vehicle is
in motion (The ICU and non-ABS junction block are
mounted to the cradle).If replacement of these
lines is necessary, only the original factory
brake line containing the flexible section must
be used.
OPERATION - BRAKE TUBES AND HOSES
The purpose of the chassis brake tubes and flex
hoses is to transfer the pressurized brake fluid devel-
oped by the master cylinder to the wheel brakes of
the vehicle. The flex hoses are made of rubber to
allow for the movement of the vehicle's suspension.
INSPECTION - BRAKE TUBES AND HOSES
Flexible rubber hose is used at both front brakes
and at the rear axle. Inspection of brake hoses
should be performed whenever the brake system is
serviced and every 7,500 miles or 12 months, which-
ever comes first (every engine oil change). Inspect
hydraulic brake hoses for surface cracking, scuffing,
or worn spots. If the fabric casing of the rubber hose
becomes exposed due to cracks or abrasions in the
rubber hose cover, the hose should be replaced imme-
diately. Eventual deterioration of the hose can take
place with possible burst failure. Faulty installation
can cause twisting, resulting in wheel, tire, or chassis
interference.
The brake tubing should be inspected periodically
for evidence of physical damage or contact with mov-
ing or hot components.
The flexible brake tube sections used on this vehi-
cle in the primary and secondary tubes from the
master cylinder to the ABS hydraulic control unit
connections must also be inspected. This flexible tub-
ing must be inspected for kinks, fraying and contact
with other components or with the body of the vehi-
cle.

TIONAL SAFETY AND HEALTH ADMINISTRATION
(OSHA) AND THE ENVIRONMENTAL PROTECTION
AGENCY (EPA) FOR THE HANDLING, PROCESSING,
AND DISPOSING OF DUST OR DEBRIS THAT MAY
CONTAIN ASBESTOS FIBERS.
INSPECTION - DISC BRAKE SHOES
Visually inspect brake shoes (pads) for uneven lin-
ing wear. Also inspect for excessive lining deteriora-
tion. Check the clearance between the tips of the
wear indicators on the shoes (if equipped) and the
brake rotors.
If a visual inspection does not adequately deter-
mine the condition of the lining, a physical check will
be necessary. To check the amount of lining wear,
remove the disc brake shoes from the calipers.
Measure each brake shoe. The combined brake
shoe and its lining material thickness should be mea-
sured at its thinnest point.
²For front disc brake shoes, when a set of brake
shoes are worn to a thickness of approximately 7.95
mm (5/16 inch), they should be replaced.
²For rear disc brake shoes, when a set of brake
shoes are worn to a thickness of approximately 7.0
mm (9/32 inch), they should be replaced.
²Typically, if front shoes are worn out, both fronts
and rears need to be replaced. Make sure to check
rears.
