WARNING: DO NOT REMOVE THE STRUT SHAFT
NUT BEFORE THE COIL SPRING IS COMPRESSED.
THE COIL SPRING IS HELD UNDER PRESSURE
AND MUST BE COMPRESSED, REMOVING SPRING
TENSION FROM THE UPPER MOUNT AND PIVOT
BEARING, BEFORE THE SHAFT NUT IS REMOVED.
(1) Position the strut assembly in the strut coil
spring compressor following the manufacturers
instructions. Position the lower hooks on the coil
spring first. The strut clevis bracket should be posi-
tioned straight outward from the compressor.
(2) Turn the upper mount of the strut assembly
toward the inside of the compressor as shown to
allow positioning of the compressor upper hooks (Fig.
44). Position the upper hooks on top of the coil spring
upper seat approximately 1 inch from outside diame-
ter of seat (Fig. 47).Do not allow hooks to be
placed closer to edge.Place a clamp on the lower
end of the coil spring, so the strut is held in place
once the strut shaft nut is removed.
(3) Compress the coil spring until all coil spring
tension is removed from the upper mount.
(4) Install Strut Nut Socket, Special Tool 6864, on
the strut shaft retaining nut (Fig. 45). Next, install a
10 mm socket on the hex on the end of the strut
shaft. While holding the strut shaft from turning,
remove the nut from the strut shaft.
(5) Remove the upper mount from the strut shaft.
(6) If the pivot bearing needs to be serviced,
remove it from the top of the coil spring upper seat
by pulling it straight up.
(7) Remove the clamp from the bottom of the coil
spring and remove the strut out through the bottom
of the coil spring.NOTE: If the coil spring or upper spring seat needs
to be serviced, proceed with the next step, other-
wise, proceed with step 10.
(8) Release the tension from the coil spring by
backing off the compressor drive fully. Push back the
compressor upper hooks and remove the upper spring
seat with upper spring isolator.
(9) Remove the coil spring from the spring com-
pressor.

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).

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

BRAKE FLUID LEVEL SWITCH
DESCRIPTION
The brake fluid level switch is located in the brake
fluid reservoir of the master cylinder (Fig. 4).
OPERATION
The purpose of the brake fluid level switch is to
provide the driver with an early warning that the
brake fluid level in the master cylinder fluid reser-
voir has dropped below a normal level. This may
indicate:
²Abnormal loss of brake fluid in the master cyl-
inder fluid reservoir resulting from a leak in the
hydraulic system.
²Brake shoe linings which have worn to a point
requiring replacement.
As the brake fluid drops below the minimum level,
the brake fluid level switch closes to complete the red
BRAKE warning indicator (lamp) circuit. This will
turn on the red BRAKE warning indicator. The mas-
ter cylinder fluid reservoir should be checked and
refilled to the Full mark with DOT 3 brake fluid.If
the brake fluid level has dropped below the add

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.
Replacebothdisc brake shoes (inboard and out-
board) on each caliper. It is necessary to replace the
shoes on the opposite side of the vehicle as well as
the shoes failing inspection.If the brake shoe assemblies do not require
replacement, be sure to reinstall the brake shoes in
the original position they were removed from.
INSTALLATION
INSTALLATION - FRONT DISC BRAKE SHOES
(DISC/DISC BRAKES)
NOTE: There may be more than 1 lining material
released. Make sure proper linings are being
installed.
(1) Begin on one side of the vehicle or the other.
(2) Completely retract the caliper piston back into
its bore in the brake caliper (This is required for cal-
iper installation on the brake rotor with new brake
shoes installed).
(3) If applied, remove the protective paper from
the noise suppression gasket on the rear of both the
inner and outer brake shoe assemblies.
(4) Install the new inboard brake shoe into the cal-
iper piston by firmly pressing its retaining clip into
the piston bore. Be sure the inboard brake shoe is
positioned squarely against the face of the caliper
piston.
(5) Lubricate both adapter abutments where the
shoes slide with a small amount of MopartDielectric
grease, or equivalent.
(6) Slide the new outboard brake shoe into the cal-
iper adapter with the lining up against the outside of
the brake rotor.
CAUTION: Use care when installing the caliper
assembly onto the caliper adapter, so the caliper
guide pin bushings do not get damaged by the
adapter bosses.
(7) Carefully position the brake caliper over the
brake rotor and adapter.
(8) Install the caliper guide pin bolts and tighten
to a torque of 35 N´m (26 ft. lbs.).Extreme caution
should be taken not to cross thread the caliper
guide pin bolts.
(9) Install the caps over the caliper guide pin bolts.
(10) Install the new caliper hold down spring (anti-
rattle clip) on the outboard side of the caliper. Start
the spring into the holes on the caliper, then stretch
the clip legs past the abutments on the caliper
adapter.
(11) Repeat the above procedure on other side of
the vehicle.
(12) Install the wheel and tire assemblies. Tighten
the wheel mounting nuts in proper sequence until all
nuts are torqued to half specification, then repeat the

(7) Remove the outboard brake shoe from the cali-
per. Brake shoe is removed by pushing the shoe
toward the piston, disengaging the two metal protru-
sions on the shoe back, then sliding the brake shoe
off the caliper.
(8) Remove inboard brake shoe from caliper.
