The strut assembly must be removed from the
vehicle for it to be disassembled and assembled.
For the disassembly and assembly of the strut
assembly, use of Strut Spring Compressor, Pentastar
Service Equipment (PSE) tool W-7200, or the equiva-
lent, is recommended to compress the coil spring.
Follow the manufacturer's instructions closely.
WARNING: DO NOT REMOVE THE STRUT SHAFT
NUT BEFORE THE COIL SPRING IS COMPRESSED.
THE COIL SPRING IS HELD UNDER PRESSURE
AND MUST BE COMPRESSED, REMOVING SPRING
TENSION FROM THE UPPER MOUNT AND PIVOT
BEARING, BEFORE THE SHAFT NUT IS REMOVED.
(1) Position the strut assembly in the strut coil
spring compressor following the manufacturers
instructions. Position the lower hooks on the coil
spring first. The strut clevis bracket should be posi-
tioned straight outward from the compressor.
(2) Turn the upper mount of the strut assembly
toward the inside of the compressor as shown to
allow positioning of the compressor upper hooks (Fig.
44). Position the upper hooks on top of the coil spring
upper seat approximately 1 inch from outside diame-
ter of seat (Fig. 47).Do not allow hooks to be
placed closer to edge.Place a clamp on the lowerend of the coil spring, so the strut is held in place
once the strut shaft nut is removed.
(3) Compress the coil spring until all coil spring
tension is removed from the upper mount.
(4) Install Strut Nut Socket, Special Tool 6864, on
the strut shaft retaining nut (Fig. 45). Next, install a
10 mm socket on the hex on the end of the strut
shaft. While holding the strut shaft from turning,

ASSEMBLY - STRUT ASSEMBLY
For the disassembly and assembly of the strut
assembly, use of Strut Spring Compressor, Pentastar
Service Equipment (PSE) tool W-7200, or the equiva-
lent, is recommended to compress the coil spring.
Follow the manufacturer's instructions closely.NOTE: Coil Springs on this vehicle are side-ori-
ented. Springs on the left side of the vehicle have a
left-hand wind top-to-bottom while springs on the
right side have a right-hand wind top-to-bottom.
Left and right springs must not be interchanged.
NOTE: If the coil spring has been removed from the
spring compressor, proceed with the next step, oth-
erwise, proceed with step 5.
(1) Place the coil spring in the compressor lower
hooks following the manufacturers instructions.
Proper orientation of the spring to the strut (once
installed) is necessary. Consider the following when
placing the coil spring in the compressor: From
above, the compressor back is at the 12 o'clock posi-
tion, and you, standing in the front of the machine,
are at the 6 o'clock position. Place the lower coil
spring end at the 6 o'clock position for both left and
right springs. (Fig. 46).
(2) Install the upper seat and upper isolator on top
of the coil spring. Position the notch in the perimeter
of the upper seat toward the front of the compressor
(same 6 o'clock position as in step 1).
(3) Position the upper hooks on top of the coil
spring upper seat so the upper hooks span approxi-
mately 1 inch past outside diameter of upper seat
(Fig. 47). This will allow proper clearance for upper
mount installation without pinching the hooks in-be-
tween the two pieces.Do not allow hooks to be
placed closer to edge.
(4) Compress the coil spring far enough to allow
strut installation.

(5) If the pivot bearing has been removed from the
upper seat, install the pivot bearing on the top of the
upper spring seat (Fig. 48). The bearing must be
installed on upper seat with the smaller diameter
side of the pivot bearing toward the spring seat. Be
sure the pivot bearing is sitting flat on the spring
seat once mounted.
(6) Install the spring isolator on the lower spring
seat of the strut (Fig. 38).
(7) Install the jounce bumper on the strut shaft
(Fig. 38). The jounce bumper is to be installed with
the small end pointing downward.
(8) Install the dust shield on the strut. Collapse
and stretch the dust shield down over the top of the
jounce bumper until the dust shield snaps into theslot on the jounce bumper. The jounce bumper will be
at the top of the inner dust boot. Return the dust
shield to its fully extended length.
(9) Install the strut through the bottom of the coil
spring until the lower spring seat contacts the lower
end of the coil spring. The clevis bracket on the strut
should point straight outward away from the com-
pressor (to the 6 o'clock position). This position
should be within 5É of the lower end tip of the coil
spring (Fig. 49). If necessary, reposition the strut or
coil spring in the compressor so both of these line up
straight outward away from the compressor (to the 6
o'clock position). Install the clamp to hold the strut
and coil together.
(10) Install the strut mount over the strut shaft
and onto the top of the pivot bearing and upper seat
as shown (Fig. 44). Loosely install the retaining nut
on the strut shaft.
(11) Install Strut Nut Socket (on the end of a
torque wrench), Special Tool 6864, on the strut shaft
retaining nut (Fig. 45). Next, install a 10 mm socket
on the hex on the end of the strut shaft. While hold-
ing the strut shaft from turning, tighten the strut
shaft retaining nut to a torque of 100 N´m (75 ft.
lbs.).
NOTE: Before releasing the tension the compressor
has on the spring, using the following figure as ref-
erence (Fig. 50), make sure the upper spring seat,
coil spring and strut clevis bracket are all lined up
properly (within 5É of one another).

HUB / BEARING
DESCRIPTION
The rear wheel bearing and rear wheel hub of this
vehicle are a one-piece sealed unit, or hub and bear-
ing unit type assembly (Unit III). The hub and bear-
ing is mounted to the center of the rear axle using 4
mounting bolts. It has five wheel mounting studs on
the hub flange.
All-Wheel-Drive vehicles have a hub and bearing
unit with a splined hole in the center of the hub for
rear driveshaft stub axle acceptance.
Front-Wheel-Drive vehicles with antilock brakes
have an internally mounted wheel speed sensor and
tone wheel. This hub and bearing can be identified
by the rounded cap and molded in connector on the
rear of the assembly (Fig. 7). The sensor and tone
wheel cannot be serviced separately from the hub
and bearing.

OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the tire and wheel
assembly (and driveshaft on All-Wheel-Drive vehi-
cles). The five wheel mounting studs mount the tire
and wheel assembly, and disc brake rotor or brake
drum to the vehicle.
On All-Wheel-Drive vehicles, the splined mating of
the driveshaft stub axle and hub allows the drive-
shaft to rotate with the hub and wheel.
Front-Wheel-Drive vehicles equipped with antilock
brakes have a wheel speed sensor and tone wheel
mounted to the rear of the hub and bearing. The tone
wheel rotates with the hub which is sensed by the
wheel speed sensor.
DIAGNOSIS AND TESTING - HUB AND
BEARING
The bearing contained in the hub and bearing
assembly will produce noise and vibration when worn
or damaged. The noise will generally change when
the bearings are loaded. A road test of the vehicle is
normally required to determine the location of a
worn or damaged bearing.
Find a smooth level road surface and bring the
vehicle up to a constant speed. When vehicle is at a
constant speed, swerve the vehicle back and forth
from the left and to the right. This will load and
unload the bearings and change the noise level.
When bearing damage is slight, the noise is some-
times noticeable at lower speeds and at other times
is more noticeable at speeds above 105 km/h (65
mph).
