member in place). Remove the stabilizer bar from the
vehicle.
(5) Mount the stabilizer bar in a soft jawed vise
with one of the two bushings mount just above the
vise jaws.
(6) Carefully pry back the retainer tabs on the
wider end of the upper bushing retainer away from
the lower half.
(7) Using a hammer and a brass drift punch, tap
the upper half of the bushing retainer assembly for-
ward, off of the lower half and bushing (Fig. 17).
(8) Remove the lower half of the bushing retainer
from the bushing.
(9) Remove the bushing from the stabilizer bar.
Make note that the slit in the bushing points
toward the front of the vehicle.
(10) Remove the stabilizer bar from the vise, and
repeat the preceding 5 steps to remove the second
bushing from the other side of the stabilizer bar.
INSTALLATION - STABILIZER BAR (REAR)
NOTE: Inspect the bushings and retainers for
cracks and distortion. If any signs appear, these
pieces should be replaced.
(1) Install the bushings onto the stabilizer bar.
Make sure that the slit in the bushing points
toward the front of the vehicle.
(2) Mount the stabilizer bar in the soft jawed vise
with the bushing just above the top of the vise jaws.
(3) Install the lower half of the retainer onto the
bushing with the elongated mounting hole towards
the front of the vehicle.
(4) Install the upper half of the retainer onto the
lower half. This is done by tapping the upper half,
starting with the large end, onto the lower half with
a hammer and brass drift punch (Fig. 18). Tap the
upper retainer half on until the mounting holes line
up with the ones in the lower half.
(5) Using a pair of pliers, bend the retainer tabs
on the upper retainer half around the lower retainer
half, securing the two halves together.
(6) Remove the stabilizer bar from the vise, and
repeat the preceding 5 steps to install the second
bushing and retainer on the other side of the stabi-
lizer bar.
(7) Position the rear stabilizer bar in position
between the frame rails. Install the 4 bolts attaching
both stabilizer bar isolator bushing retainers to the
frame rails (Fig. 16) (the 2 rearward attaching bolts
attach the front corners of the rear suspension cross-
member in place). Tighten the forward stabilizer bar
isolator bushing retainer attaching bolts to 40 N·m
(30 ft. lbs.). Tighten the 2 rearward stabilizer bar iso-
lator bushing retainer attaching bolts (which also
serve as the forward rear crossmember attaching
bolts) to 100 N·m (75 ft. lbs.).
(8) Install the screw securing the brake tubes to
the left stabilizer bar isolator bushing retainer (Fig.
16).
(9) Install both stabilizer bar attaching links onto
stabilizer bar (Fig. 15). Install both stabilizer link to
stabilizer bar attaching nuts (Fig. 15). Tighten the
stabilizer link to stabilizer bar attaching nuts to a
torque of 95 N·m (70 ft. lbs.) using a crow foot

(10) Lower vehicle to the ground.
STRUT
DESCRIPTION - STRUT ASSEMBLY (REAR)
The rear strut assemblies support the weight of
the vehicle using coil springs positioned around the
struts (Fig. 1). The coil springs are contained
between the upper mount of the strut assembly and
a lower spring seat on the body of the strut assembly.
The top of each strut assembly is bolted to the top
of the inner fender through the rubber isolated upper
mount.
The bottom of the strut assembly attaches to the
spindle. Strut attachment to the spindle is accom-
plished using a split collar on the rear spindle. The
collar uses a pinch bolt to retain the spindle to the
strut.
The rear coil springs are rated separately for each
corner or side of the vehicle depending on optional
equipment and type of vehicle service. Coil springs
come in a various rates; be sure the correct spring is
in use.
The components of the strut assembly listed below
are serviceable if found to be defective (Fig. 19).
• Strut shaft retainer nut
• Upper mount
• Dust shield
• Jounce bumper
• Coil spring
• Upper spring isolator
• Lower spring isolator
• Strut (damper)
OPERATION - STRUT ASSEMBLY (REAR)
The rear strut assemblies support the weight of
the vehicle. They cushion the ride of the vehicle, con-
trolling vibration, jounce and rebound of the suspen-
sion.
The coil spring controls ride quality and maintains
ride height.
The jounce bumper limits suspension travel and
metal-to-metal contact under full jounce.
The strut dampens jounce and rebound motions of
the coil spring and suspension.
DIAGNOSIS AND TESTING - STRUT ASSEMBLY
(REAR)
(1) Inspect for damaged or broken coil springs
(Fig. 19).
(2) Inspect for torn or damaged strut assembly
dust boots (Fig. 19).
(3) Inspect for damaged upper and lower spring
isolators (Fig. 19).
(4) Lift dust boot and inspect strut assembly for
evidence of fluid running from the upper end of fluid
reservoir. (Actual leakage will be a stream of fluid
running down the side and dripping off lower end of
unit). A slight amount of seepage between the strut
rod and strut shaft seal is not unusual and does not
affect performance of the strut assembly. Also inspect
jounce bumpers inside dust boot for signs of damage
or deterioration.
(5) Verify correct struts and coil springs are
installed on vehicle.
Coil springs are rated separately for each side of
vehicle depending on optional equipment and type of
service.
NOTE: If the coils springs require replacement, be
sure that the springs being replaced, are replaced
with springs meeting the correct load and spring
rate for the vehicle.
Replacement of the coil spring requires removal
and disassembly of the strut assembly. (Refer to 2 -

REMOVAL - STRUT ASSEMBLY (REAR)
NOTE: When removing rear strut assembly from
vehicle, access to the 3 rear strut assembly-to-strut
tower attaching nuts is through the passenger com-
partment of the vehicle.
(1) Remove the rear seat cushion from the interior
of the car. Refer to Body/Seats.
(2) Remove the rear seat back assembly. Refer to
Body/Seats.
(3) Remove both upper quarter trim panels from
the rear of the vehicle interior. Refer to Body/Interior.
(4) Remove both lower quarter trim panels from
the rear of the vehicle interior. Refer to Body/Interior.
(5) Remove the rear parcel shelf trim panel from
the vehicle interior. Refer to Body/Interior.
NOTE: The speaker should be removed from the
vehicle with the mounting plate attached
(6) Remove the 4 screws securing the rear speaker
and mounting plate in place for the side of the vehi-
cle requiring repair. Unplug the wiring from the
speaker, then remove the speaker and mounting
plate from the vehicle.
(7) Raise vehicle on jack stands or centered on a
frame contact hoist. See Hoisting in Lubrication and
Maintenance.
(8) Remove the rear wheel and tire assembly from
the vehicle.
(9) Remove the rear caliper assembly from the
adapter. Refer to Brakes/Disc Brake Caliper. After
removing the caliper assembly, store the caliper by
hanging it from the underside of the vehicle (Fig. 20).
Do not let the rear caliper assembly hang by flexible
brake hose.
(10) If loose on wheel mounting studs, remove rear
brake rotor from hub.
(11) If
the
vehicle
is
equipped
with
antilock
brakes, remove the wheel speed sensor from the disc
brake caliper adapter by removing the bolt, then the
sensor (Fig. 21).
(12) Remove the lateral links from the spindle
(Fig. 22). This requires the removal of one long bolt
attaching both links to the spindle (Fig. 22).
(13) Install a thin wrench on the hex of the stabi-
lizer bar attaching link stud to keep the stud from
turning in the link. Next, remove the nut from the
stabilizer bar attaching link stud at the stabilizer bar
(Fig. 23). Remove the link from the stabilizer bar.

(14) Loosen and fully remove, the rear spindle to
strut assembly pinch bolt (Fig. 24).
CAUTION: When inserting center punch into rear
spindle, use care so point of center punch does not
puncture strut assembly.
(15) Insert a center punch into the hole on the
spindle (Fig. 25). Center punch must be tapped into
spindle until jammed into hole. This will spread spin-
dle casting allowing it to be removed from strut
assembly.
(16) Using a hammer and a brass drift punch, tap
on top surface of spindle driving it down and off the
end of the strut assembly (Fig. 26).
(17) Let the rear spindle and assembled compo-
nents hang from the trailing arm while the strut
assembly is out of the vehicle.
