(3) Install shock absorber by setting lower end into
pocket in spring link (Fig. 36), then tipping top
inward until aligned with mounting holes (Fig. 32).
(4) Start shock absorber upper mounting bolts
(Fig. 32), but do not tighten at this time.
(5) Carefully raise jack, guiding coil spring and
lower end of shock absorber into mounted positions.
Once shock absorber lower mounting hole lines up
with hole in spring link, stop jacking.
(6) Install lower shock mounting bolt (Fig. 33). Do
not tighten at this time.
(7) Continue to raise crossmember with jack until
two crossmember mounting bolts can be installed
and tightened (Fig. 35). Tighten bolts to 163 N·m
(120 ft. lbs.) torque.
(8) Tighten shock absorber upper mounting bolts
to 61 N·m (45 ft. lbs.) torque.
(9) Lower and remove jack.
(10) Install wheel and tire assembly. (Refer to 22 -
TIRES/WHEELS - INSTALLATION). Tighten the
wheel nuts in the proper sequence to 135 N·m (100
ft. lbs.) torque.
(11) Lower vehicle.
(12) Position vehicle on alignment rack/drive-on
hoist. Raise vehicle as necessary to access mounting
bolt.
(13) Tighten shock absorber lower mounting bolt
to 102 N·m (75 ft. lbs.) torque.

REMOVAL
(1) Disconnect and isolate battery negative cable
from battery post.
(2) If vehicle is not equipped with All Wheel Drive
(AWD), remove spare tire.
(3) Lock out automatic adjuster in parking brake
lever. (Refer to 5 - BRAKES/PARKING BRAKE -
STANDARD PROCEDURE)
(4) Raise and support vehicle. (Refer to LUBRICA-
TION & MAINTENANCE/HOISTING - STANDARD
PROCEDURE)
(5) Position an extra pair of jack stands under and
support forward end of engine cradle to help stabilize
vehicle during rear suspension removal/installation.
(6) Remove both rear wheel and tire assemblies.
(Refer to 22 - TIRES/WHEELS - REMOVAL)
(7) Remove rear half of exhaust system. (Refer to
11 - EXHAUST SYSTEM - REMOVAL)
NOTE: It may be necessary to back off parking
brake shoe adjustment to allow sufficient slack to
disengage cable buttons from connectors in follow-
ing two steps.
(8) Slide left rear parking brake cable button
inboard and remove from equalizer (Fig. 37).
(9) While holding parking brake cable connector on
end of front cable secure with a pair of pliers at the
front cable button, slide right rear parking brake
cable button inboard and remove from cable connec-
tor (Fig. 37).
(10) Remove screw mounting left rear brake hose
routing bracket to front of rear crossmember (Fig.
38).
(11) Remove screw mounting right rear brake hose
routing bracket to front of rear crossmember (Fig.
38).
NOTE: In some cases, it may be necessary to
retract caliper piston in its bore a small amount in
order to provide sufficient clearance between shoes
and rotor to easily remove caliper from knuckle.
This can usually be accomplished before guide pin
bolts are removed, by grasping rear of caliper and
pulling outward working with guide pins, thus
retracting piston. Never push on piston directly as
it may get damaged.
(12) Remove each rear caliper from its mount and
support as follows:
(a) Remove two caliper guide pin bolts (Fig. 39).
(b) Remove caliper assembly from brake adapter
by first rotating bottom of caliper away from rotor,
then lifting caliper (with shoes) away from upper
adapter abutment (Fig. 40).

(c) To prevent weight of caliper from overextend-
ing and damaging brake hose and tubing while cal-
iper is off mount, hang brake caliper from vehicle
using wire or cord (Fig. 41). Be sure to hang cal-
iper and brake hose far enough forward on
body, away from crossmember, to allow suffi-
cient room to lower crossmember without
interference.
(13) Disconnect vehicle wiring harness from each
rear wheel speed sensor connector (Fig. 42).
(14) Unclip each rear wheel speed sensor connector
from spare tire mounting support (Fig. 42).
(15) If equipped with AWD:

(a) Reference mark propeller shaft-to-rear driv-
eline module input flange connection.
(b) Remove three propeller shaft-to-rear driv-
eline module mounting bolts. Do not attempt
removal of shaft from module at this time due to
alignment pin interference. Removal happens as
crossmember is lowered in a later step.
(16) Carefully mark location of rear crossmember
on body at all four mount (bushing) locations using a
marker or crayon (Fig. 43). Do not use a scratch
awl to mark location.
(17) Position under-hoist utility jack or transmis-
sion jack under center of rear suspension crossmem-
ber (without AWD) or rear driveline module (with
AWD) (Fig. 34). Raise jack head to contact driveline
module/suspension crossmember and secure in place.
(18) Remove lower mounting bolt and nut at each
rear shock absorber (Fig. 33).
(19) Remove both front and rear crossmember
mounting bolts on left side of vehicle (Fig. 35).
CAUTION: To avoid damaging other components of
vehicle, do not lower crossmember any further than
necessary to remove coil spring.
(20) Slowly lower jack allowing left side of cross-
member to drop. Do not lower jack at a fast rate.
Lower jack just enough to allow spring removal. Do
not lower jack any further than necessary.
(21) Remove coil spring and isolator (Fig. 36),
lower end first.
(22) Raise left side of crossmember back into
mounted position and install previously removed
mounting bolts. It is not necessary to tighten bolts at
this point.
(23) Remove both front and rear crossmember
mounting bolts on right side of vehicle (Fig. 35).

CAUTION: To avoid damaging other components of
vehicle, do not lower crossmember any further than
necessary to remove coil spring.
(24) Slowly lower jack allowing right side of cross-
member to drop. Do not lower jack at a fast rate.
Lower jack just enough to allow spring removal. Do
not lower jack any further than necessary.
(25) Remove coil spring and isolator (Fig. 36),
lower end first.
(26) Raise right side of crossmember back into
mounted position. It is not necessary to install
mounting bolts.
(27) Remove both front and rear crossmember
mounting bolts previously removed on left side of
crossmember (Fig. 35).
(28) Slowly lower jack. Do not lower jack at a
fast rate. As jack is lowered, remove propeller shaft
from alignment pin on end of rear driveline module
input flange and support it with a bungee or cord,
keeping it at its normal height. Do not allow pro-
peller shaft to hang on its own.
(29) Continue to lower jack until crossmember is
at a comfortable working level to access stabilizer bar
fasteners.
(30) Remove bolt and nut fastening stabilizer bar
to each stabilizer link (Fig. 44).
(31) Remove bolts fastening each stabilizer bar
cushion retainer to crossmember (Fig. 44).
(32) Remove stabilizer bar with cushions and
retainers.
(33) Remove retainers from cushions.
(34) Remove cushions from stabilizer bar utilizing
slits in bushings.
INSTALLATION
(1) Install cushions on stabilizer bar utilizing slits
in bushings. Install each cushion so its slit faces for-
ward and flat side is positioned toward crossmember
once installed.
(2) Install retainers on cushions.
(3) Install stabilizer bar with cushions and retain-
ers on crossmember.
(4) Install cushion retainer mounting bolts (Fig.
44). Do not tighten at this time.

each stabilizer link (Fig. 44). Do not tighten at this
time.
(6) Tighten cushion retainer mounting bolts to 61
N·m (45 ft. lbs.) torque.
(7) Raise crossmember to body mounting points. As
crossmember is raised, slide propeller shaft onto
alignment pin on end of rear driveline module input
flange and align shocks with pockets in spring links.
(8) Continue to raise crossmember with jack until
two crossmember mounting bolts can be installed
(Fig. 35). Install left side crossmember mounting
bolts, but not the right side bolts (Fig. 35). It is not
necessary to tighten bolts at this point.
CAUTION: To avoid damaging other components of
vehicle, do not lower crossmember any further than
necessary to install coil spring.
(9) Slowly lower jack allowing right side of cross-
member to drop. Do not lower jack at a fast rate.
Lower jack just enough to allow spring Installation.
Do not lower jack any further than necessary.
(10) Install coil spring and isolator (Fig. 36), top
end first.
NOTE: Verify spring lower end coil is correctly
placed against abutment built into spring link.
(11) Carefully raise jack, guiding coil spring and
lower end of shock absorber into mounted positions.
Once shock absorber lower mounting hole lines up
with hole in spring link, stop jacking.
(12) Install lower shock mounting bolt (Fig. 33).
Do not tighten at this time.
(13) Raise right side of crossmember into mounted
position. Install right side crossmember mounting
bolts (Fig. 35). Snug, but do not fully tighten
bolts at this time.
