Chrysler Pacifica. Manual — part 425

(14) Remove clamp from lower end of coil spring

and strut. Push back spring compressor upper and
lower hooks, then remove strut assembly from spring
compressor.

(15) Install strut assembly on vehicle. (Refer to 2 -

SUSPENSION/FRONT/STRUT - INSTALLATION)

INSTALLATION

CAUTION: When installing a strut assembly, make
sure strut being installed has correct coil spring for
that side of vehicle. Do not interchange two sides.

(1) Install strut assembly into strut tower, aligning

and installing three studs on upper strut mount into
holes in tower. Install three mounting nut/washer
assemblies (Fig. 28). Tighten nuts to 28 N·m (250 in.
lbs.) torque.

(2) If servicing left strut assembly, place coolant

recovery bottle in its normal mounted position and
install nuts fastening it in place. (Refer to 7 - COOL-
ING/ENGINE/COOLANT RECOVERY PRESS CON-
TAINER - INSTALLATION)

CAUTION:

Steering

knuckle

to

strut

assembly

attaching bolts are serrated and must not be turned
during installation. Install nuts while holding bolts
stationary in steering knuckle.

CAUTION: If strut being serviced is equipped with a
slotted lower clevis bracket mounting hole and
eccentric cam strut attaching bolt, eccentric cam
bolt must be installed in lower (slotted) hole in strut
clevis bracket (Fig. 33).

NOTE: Strut clevis-to-steering knuckle bolts are
installed differently on each side. Left hand side
bolts are to be installed from vehicle rear to front
(Fig. 26). Right side bolts are to be installed from
vehicle front to rear (Fig. 27).

(3) Align steering knuckle in clevis bracket of

strut. Install strut clevis-to-steering knuckle attach-
ing bolts (Fig. 26) (Fig. 27). Install nuts on ends of
bolts and tighten to 81 N·m (60 ft. lbs.) torque. Then,
tighten nuts an additional 1/4 (90°) turn after that
torque is met.

(4) Install

stabilizer

bar

link

mounting

stud

through rearmost hole in bracket on strut assembly.

CAUTION: When installing nut on mounting stud of
stabilizer bar link, do not allow stud to rotate in it’s
socket. Hold stud from rotating by placing an open-
end wrench on flat machined into stud (Fig. 25).

(5) Hand thread nut on end of stabilizer bar link

stud. Hold stud from turning by placing an open-end
wrench on flat machined into link’s mounting stud,
then tighten nut while holding wrench in place (Fig.
25). Tighten nut to 88 N·m (65 ft. lbs.) torque.

(6) Attach wheel speed sensor routing bracket to

strut assembly (Fig. 24). Tighten screw to 13 N·m
(115 in. lbs.) torque.

(7) Install tire and wheel assembly (Refer to 22 -

TIRES/WHEELS - INSTALLATION). Tighten wheel
mounting nuts to a torque of 135 N·m (100 ft. lbs.).

(8) Lower vehicle.
(9) Perform wheel alignment as necessary. (Refer

to 2 - SUSPENSION/WHEEL ALIGNMENT - STAN-
DARD PROCEDURE)

REAR SUSPENSION

DESCRIPTION

This vehicle utilizes a five-link rear suspension

including the following major components (Fig. 1):

• Camber Link

• Compression Link

• Spring Link

• Tension Link

• Toe Link

• Coil Spring

• Crossmember

• Hub And Bearing

• Knuckle

• Shock Absorber (Load-Leveling)

• Stabilizer Bar
The knuckle, camber link, compression link and

tension link are aluminum castings. Extra care
needs to be taken when servicing these components.

Service Procedures for the crossmember can be

found in Frame And Bumpers. (Refer to 13 - FRAME

(9) Disconnect sensor cable from bracket on brake

support (Fig. 3).

(10) Completely loosen, but do not remove four

bolts fastening hub and bearing in place (Fig. 4).
Once loosened from threads in hub and bearing, push
bolts up against rear of hub and bearing to keep
brake support plate in place when hub and bearing is
removed.

(11) Pull hub and bearing off knuckle and half

shaft (if equipped with AWD), then thread wheel
speed sensor cable through hole in brake support
plate as it is removed with hub and bearing (Fig. 5).

INSTALLATION

(1) Position hub and bearing bolts though rear of

knuckle and parking brake support just enough to
hold support in place as hub and bearing is installed.

(2) Install hub and bearing by first feeding end of

wheel speed sensor cable through hole in bottom of
parking brake support (Fig. 5). As this is being done,
if equipped with AWD, slide hub and bearing onto
