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. 25).
(2) Squeeze tool together until top band of clamp is
latched behind the two tabs on lower band of clamp
(Fig. 26).
(14) Install the half shaft back into the vehicle.

PROPELLER SHAFT
DESCRIPTION
WARNING: Due to propeller shaft imbalance con-
cerns, the propeller shaft can only be serviced as
an assembly.
AWD models utilize a ªtwo-pieceº propeller shaft
(Fig. 1) to transmit power to the rear driveline mod-
ule assembly. This two-piece design consists of:
²Front and rear shaft segments.
²Plunging center CV joint
²Center support bearing
²Rubber coupler at driveline module flange
The front shaft segment utilizes a CV joint at the
power transfer unit connection, and a plunging CV
joint at the center bearing location.
The rear shaft segment utilizes a center support
bearing at the forward position, and a rubber coupler
at the driveline module flange.
OPERATION
The propeller shaft (Fig. 1) is used to transmit
torque from the transaxle power transfer unit (PTU)
to the rear driveline module of AWD equipped mod-
els.
The propeller shaft front half utilizes a CV joint at
the PTU flange, and a plunging CV joint at the cen-
ter bearing location. These joints are flexible, allow-
ing for torsional movement of the powertrain.The propeller shaft rear half utilizes a center sup-
port bearing, which supports this two-piece assembly.
The bearing also stabilizes the rear shaft segment to
minimize axle wind-up. The rubber coupler at the
driveline module flange dampens out propeller shaft
torsional vibrations, as the driveline module it con-
nects to is fastened to the vehicle body.
REMOVAL
CAUTION: Propeller shaft removal is a two-man
operation. Never allow propeller shaft to hang while
connected to power transfer unit (PTU) or rear driv-
eline module flanges. A helper is required.
(1) Make sure transaxle is in neutral (N). Using
chalk, mark propeller shaft flanges at PTU and rear
driveline module for installation reference.
(2) Remove six propeller shaft-to-power transfer
unit bolts.
(3) Have helper remove three propeller shaft rub-
ber coupler-to-driveline module bolts while he/she
supports rear shaft by hand.
(4) Remove center bearing support-to-crossmember
bolts, while supporting front shaft with two hands.
(5) Lower propeller shaft assembly to ground,
using care not to damage fore and aft flanges (Fig.
1).

REAR DRIVELINE MODULE
DESCRIPTION
The rear driveline module assembly (Fig. 1) con-
sists of four main components:
²Bi-Directional Overrunning Clutch (BOC)
²Viscous Coupling
²Differential Assembly
²Torque Arm
The viscous coupling and bi-directional overrun-
ning clutch are contained within an overrunning
clutch housing, which fastens to the differential
assembly. The overrunning clutch housing and differ-
ential assembly have unique fluid sumps, each
requiring their own type and capacity of fluid. The
overrunning clutch housing requires MopartATF+4
(Automatic Transmission FluidÐType 9602) or equiv-
alent. The differential assembly requires Mopart
80W-90 Gear and Axle Lubricant.
Driveline module service is limited to the following
components:
²Differential Assembly (serviced only as assem-
bly)
²Viscous Coupling
²Bi-Directional Overrunning Clutch (BOC)
²Overrunning Clutch Housing²Seals (Input Flange, Output Flange, Overrun-
ning Clutch Housing O-rings)
²Input Flange/Shield
²Torque Arm
²Vents
²Fasteners
OPERATION
The primary benefits of All Wheel Drive are:
²Superior straight line acceleration, and corner-
ing on all surfaces
²Better traction and handling under adverse con-
ditions, resulting in improved hill climbing ability
and safer driving.
The heart of the system is an inter-axle viscous
coupling. The vehicle retains predominantly front-
wheel drive characteristics, but the All Wheel Drive
capability takes effect when the front wheels start to
slip. Under normal level road, straight line driving,
100% of the torque is allocated to the front wheels.
The viscous coupling controls and distributes torque/
power to the rear wheels. The viscous coupling trans-
mits torque to the rear wheels in proportion of the
amount of the slippage at the front wheels. Thais
variable torque distribution is automatic with no
driver inputs required. The coupling is similar to a
multi-plate clutch. It consists of a series of closely
spaced discs, which are alternately connected to the

DISASSEMBLY
WARNING: Differential is only to be serviced as an
assembly, and no disassembly is required.
(1) Remove six torque arm-to-differential case
bolts and remove torque arm assembly (Fig. 4).

WARNING
WARNING: DUST AND DIRT ACCUMULATING ON
BRAKE PARTS DURING NORMAL USE MAY CON-
TAIN ASBESTOS FIBERS FROM PRODUCTION OR
AFTERMARKET BRAKE LININGS. BREATHING
EXCESSIVE CONCENTRATIONS OF ASBESTOS
FIBERS CAN CAUSE SERIOUS BODILY HARM.
EXERCISE CARE WHEN SERVICING BRAKE
PARTS. DO NOT SAND OR GRIND BRAKE LINING
UNLESS EQUIPMENT USED IS DESIGNED TO CON-
TAIN THE DUST RESIDUE. DO NOT CLEAN BRAKE
PARTS WITH COMPRESSED AIR OR BY DRY
BRUSHING. CLEANING SHOULD BE DONE BY
DAMPENING THE BRAKE COMPONENTS WITH A
FINE MIST OF WATER, THEN WIPING THE BRAKE
COMPONENTS CLEAN WITH A DAMPENED CLOTH.
DISPOSE OF CLOTH AND ALL RESIDUE CONTAIN-
ING ASBESTOS FIBERS IN AN IMPERMEABLE
CONTAINER WITH THE APPROPRIATE LABEL. FOL-
LOW PRACTICES PRESCRIBED BY THE OCCUPA-
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.
CAUTION
CAUTION: During service procedures, grease or
any other foreign material must be kept off brake
shoe assemblies, and braking surfaces of brake
rotor or drum, and external surfaces of hub and
bearing assembly.
CAUTION: Handling of brake rotors and calipers
must be done in such a way as to avoid damage to
the rotor and scratching or nicking of brake lining
on the brake shoes.
CAUTION: At no time when servicing a vehicle, can
a sheet metal screw, bolt or other metal fastener be
installed in the shock tower to take the place of an
original plastic clip. Also, NO holes can be drilled
into the front shock tower in the area shown in (Fig.
1), for the installation of any metal fasteners into
the shock tower. Because of the minimum clear-ance in this area (Fig. 1), installation of metal fas-
teners could damage the coil spring coating and
lead to a corrosion failure of the spring. If a plastic
clip is missing, or is lost or broken during servicing
a vehicle, replace only with the equivalent part
listed in the Mopar parts catalog.
CAUTION: Only the recommended jacking or hoist-
ing positions for this vehicle are to be used when-
ever it is necessary to lift a vehicle. Failure to raise
a vehicle from the recommended locations could
result in lifting a vehicle by the hydraulic control
unit mounting bracket. Lifting a vehicle by the
hydraulic control unit mounting bracket will result
in damage to the mounting bracket and the hydrau-
lic control unit.
