(10) Move the support plate or disc brake adapter
away from the axle. At the same time, loosen the
spindle from the axle and remove it from the back of
the support plate or disc brake adapter.
INSTALLATION
(1) Place a new seal on the spindle (Fig. 26).
(2) Install the spindle from the back side into the
support plate (drum brakes) or disc brake adapter,
then place it into its mounting position on the end of
the axle (Fig. 26).
NOTE: When performing the following step, use
new mounting bolts or clean and apply Mopar
T
Stud & Bearing Mount Adhesive or equivalent to the
original mounting bolt threads before reuse.
(3) Place the support plate (drum brakes) or disc
brake adapter up against the spindle, then install
the four bolts securing the brake shoe support plate
or disc brake adapter, and the spindle to the axle.
Tighten the mounting bolts to a torque of 95 N·m (70
ft. lbs.).
(4) On vehicles equipped with antilock brakes,
install the wheel speed sensor in the disc brake
adapter and install the bolt securing it in place (Fig.
29). Tighten the wheel speed sensor mounting bolt to
a torque of 12 N·m (105 in. lbs.).
(5) Align the parking brake cable routing brackets
with their mounts on the trailing arm. Install the
two bolts securing the cable and routing brackets to
the trailing arm (Fig. 28). Install and tighten the
mounting bolts to a torque of 11 N·m (100 in. lbs.).
(6) Install the hub and bearing on the spindle (Fig.
26). Install a NEW hub and bearing retaining nut.
Tighten the retaining nut to a torque of 217 N·m
(160 ft. lbs.).
(7) Install the hub and bearing dust cap.
NOTE: On vehicles with rear drum brakes, before
installing the drum, it may be necessary to adjust
the rear brakes. (Refer to 5 - BRAKES/HYDRAULIC/
MECHANICAL/BRAKE
PADS/SHOES
-
ADJUST-
MENTS)
(8) On drum brake equipped vehicles, install the
brake drum.
(9) On vehicles equipped with rear disc brakes
(Fig. 27):
(a) Install the brake rotor.
(b) Install the disc brake caliper.
(c) Install the caliper guide pin bolts, then
tighten them to a torque of 22 N·m (192 in. lbs.).
(10) Install the bolts securing the disc brake flex
hose or drum brake flex hose to the axle trailing
arm.
(11) Install the rear tire and wheel assembly.
Tighten all wheel nuts to a torque of 135 N·m (100 ft.
lbs.).
(12) Lower the vehicle.

SPRING
DESCRIPTION
The springs used on the rear suspension of this
vehicle are the coil type (Fig. 30). They are mounted
straight above the rear axle beam in line with the
rear wheels. A spring isolator is attached to each end
of the coil springs. Coil springs come in various
heights, be sure the correct spring is in use.
REMOVAL
NOTE: Before proceeding, (Refer to 2 - SUSPEN-
SION/REAR - WARNING).
(1) Raise the vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Remove both rear tire and wheel assemblies
from the vehicle.
(3) Remove the bolt securing the watts link bell
crank to the center of the axle (Fig. 30).
(4) If equipped with a rear stabilizer bar, remove
the bolts securing the stabilizer bar cushion retainers
to the rear axle (Fig. 31), then remove the stabilizer
bar from the axle.
(5) Position a transmission jack or equivalent
under the center of the axle raising it enough to sup-
port the axle.
(6) Remove the shock absorber lower mounting
bolts and nuts at the axle (Fig. 30).
(7) Lower the transmission jack until the coil
springs can be removed from the axle.
(8) Remove the coil springs and rubber isolators
(Fig. 30).

INSTALLATION
(1) Install a rubber isolator on each end of the coil
springs wrapping the rubber fingers around the coil
(Fig. 32). Turn the isolators until the rubber abut-
ment butts up against the flat end of the spring coil.
NOTE: Both ends of the coil spring are identical.
Either end of the spring can be the top or bottom.
(2) Place the coil springs on top of the axle spring
perches.
(3) The coil springs require proper orientation to
the body when installed. To do this, turn the coil
springs (along with the rubber isolators) until the
flat end of each upper spring coil lines up with an
imaginary line running parallel with the axle beam
as shown (Fig. 33). Also, make sure that the upper
coils end near the outboard sides of the vehicle and
not 180 degrees of that location.
(4) Raise the transmission jack guiding the coil
springs into the spring mounting brackets on the
body of the vehicle. Raise the jack until the shock
absorber lower mounting bolts can be installed
though the axle brackets and shock absorber lower
mounting eyes (Fig. 30).
(5) Install the washer and nut on the end of each
shock absorber lower mounting bolt. Tighten the
mounting bolts to a torque of 88 N·m (65 ft. lbs.).
(6) Remove the jack.
(7) If equipped with a rear stabilizer bar, hook the
lower ends of the stabilizer bar cushion retainers into
the slots in the back of the axle, then rotate the
opposite end of the retainers upward so the mounting
bolts can be installed. Install the mounting bolt
though each cushion retainer into the threads in the
rear axle (Fig. 31). Tighten the rear stabilizer bar
cushion retainer bolts to a torque of 61 N·m (45 ft.
lbs.).
CAUTION: When installing the watts links and bell
crank to the axle, make sure the bell crank is right-
side-up. When mounted properly, the words “BACK
UP” should be able to be read from the rear over
the top of the axle (Fig. 34).
(8) Install the bolt from the front securing the
watts link bell crank to the center of the axle (Fig.
30). Place the washer and nut on the end of the
mounting bolt and tighten it to a torque of 149 N·m
(110 ft. lbs.).
(9) Install the rear tire and wheel assemblies.
Tighten all wheel nuts to a torque of 135 N·m (100 ft.
lbs.).
(10) Lower the vehicle.
(11) Verify proper vehicle curb height. (Refer to 2 -

STABILIZER BAR
DESCRIPTION
Some versions of this vehicle are equipped with a
rear stabilizer bar. The stabilizer bar interconnects
the rear axle with the frame rails of the vehicle (Fig.
35).
Attachment of the stabilizer bar to the rear frame
rails of the vehicle is through 2 rubber-isolator stabi-
lizer bar links. The stabilizer bar attachment to the
axle is done utilizing two rubber isolated cushions
and retainers.
OPERATION
Jounce and rebound movements affecting one side
of the rear suspension are partially transmitted to
the opposite side of the rear suspension to stabilize
body roll.
