hoist. Raise vehicle as necessary to access mounting
bolts.

(9) Tighten toe link fasteners to:
• Nut at crossmember – 172 N·m (127 ft. lbs.)

torque (This nut may be tightened after rear wheel
alignment toe is set).

• Bolt at knuckle – 108 N·m (80 ft. lbs.) torque.
(10) Perform wheel alignment. (Refer to 2 - SUS-

(4) 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.

(5) Remove two shock absorber upper mounting

bolts (Fig. 32).

(6) Remove shock absorber lower mounting bolt

and nut (Fig. 33).

CAUTION: When removing crossmember mounting
bolts it is important NOT to loosen or remove
crossmember mounting bolts on opposite side of
vehicle. Doing so will require rear wheel alignment
following reinstallation to ensure proper thrust
angle.

(7) Remove both front and rear crossmember

mounting bolts on repair-side of vehicle (Fig. 35).

CAUTION: To avoid damaging other components of
vehicle, do not lower crossmember any further than
necessary to remove shock absorber or coil spring.

(8) Slowly lower jack allowing repair-side of cross-

member to drop. Do not lower jack at a fast rate.
Lower jack just enough to allow top of shock absorber
to clear body flange.

(9) Remove shock absorber by tipping top outward

and lifting lower end out of pocket in spring link
(Fig. 36).

INSTALLATION

(1) 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).

(2) Start shock absorber upper mounting bolts

(Fig. 32), but do not tighten at this time.

NOTE: In case coil spring has shifted during shock
absorber service, verify that isolator is in place and
spring lower end coil is correctly placed against
abutment built into spring link.

(3) 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.

(4) Install lower shock mounting bolt (Fig. 33). Do

not tighten at this time.

(5) 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.

(6) Tighten shock absorber upper mounting bolts

to 61 N·m (45 ft. lbs.) torque.

(7) Lower and remove jack.
(8) 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.

(9) Lower vehicle.

bolt.

(11) Tighten shock absorber lower mounting bolt to

102 N·m (75 ft. lbs.) torque.

SPRING

REMOVAL

(1) Raise and support vehicle. (Refer to LUBRICA-

TION & MAINTENANCE/HOISTING - STANDARD
PROCEDURE)

(2) Remove wheel and tire assembly. (Refer to 22 -

TIRES/WHEELS - REMOVAL)

(3) Position an extra pair of jack stands under and

support forward end of engine cradle to help stabilize
vehicle during rear suspension removal/installation.

(4) Position under-hoist utility jack or transmis-

(5) Remove two shock absorber upper mounting

bolts (Fig. 32).

(6) Remove shock absorber lower mounting bolt

and nut (Fig. 33).

CAUTION: When removing crossmember mounting
bolts it is important NOT to loosen or remove
crossmember mounting bolts on opposite side of
vehicle. Doing so will require rear wheel alignment

following reinstallation to ensure proper thrust
angle.

(7) Remove both front and rear crossmember

mounting bolts on repair-side of vehicle (Fig. 35).

CAUTION: To avoid damaging other components of
vehicle, do not lower crossmember any further than
necessary to remove shock absorber or coil spring.

(8) Slowly lower jack allowing repair-side of cross-

member to drop. Do not lower jack at a fast rate.
Lower jack just enough to allow top of shock absorber
to clear body flange.

(9) Remove shock absorber by tipping top outward

and lifting lower end out of pocket in spring link
(Fig. 36).

(10) Remove coil spring and isolator (Fig. 36),

lower end first. It may be necessary to lower jack a
little further to allow spring removal; do not lower
jack any further than necessary.

INSTALLATION

NOTE: Rear coil springs are interchangeable, but
there is a designated top and bottom to each
spring. A factory installed tag displaying “THIS END
UP”is located near the top of each spring.

(1) Place coil spring isolator on top of coil spring

(Fig. 36).

(2) Install coil spring, top end first. Match lower

end coil against abutment built into spring link.
