DESCRIPTION - REAR SUSPENSION
The rear suspension design on this vehicle uses
leaf springs, and a tube and casting axle (Fig. 1) (Fig.
2). The leaf springs used on the rear suspension of
this vehicle are of either a mono-leaf or multi-leaf
design.
There are 2 different rear suspension designs
available:
²Front-Wheel-Drive
²All-Wheel-Drive
The rear axle used on Front-Wheel-Drive applica-
tions of this vehicle is mounted to the rear leaf
springs using isolator bushings at the axle mounting
brackets.
The rear axle used on All-Wheel-Drive applications
of this vehicle is also mounted to the rear leafsprings, but does not use isolator bushings between
the rear axle and the leaf springs.
Each side of the rear suspension consists of these
major components:
²Leaf spring
²Jounce bumper
²Shock absorber
²Hub and bearing
²Track bar (one per suspension)
²Stabilizer bar (one per suspension)
OPERATION - REAR SUSPENSION
This rear suspension is designed to handle the var-
ious load requirements of the vehicle yet allow for a
comfortable ride.
The rear wheel bearings used are similar to the
bearings used in the front suspension. A hub and
bearing assembly is used.

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. The hub and bearing 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 to the vehi-
cle.
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 (REAR)
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

SHOCK ABSORBER
DESCRIPTION
There is one shock absorber on each side of the
rear suspension. The top of each shock absorber is
bolted to the frame rail. The bottom of each shock
absorber is bolted to the rear axle.
This vehicle is available with either standard type
or load-leveling shock absorbers. On the exterior,
load-leveling shock absorbers are larger in diameter
than standard shock absorbers. The load-leveling
shock absorbers mount the same as the standard
shock absorbers.
OPERATION
The shock absorber dampens jounce and rebound
motions of the spring and suspension.
Each load-leveling shock absorber is a self-leveling,
self-contained vehicle leveling system and shock
absorber combined. It does not require an external
compressor, hoses, or height leveling sensors. All the
height leveling sensors, hydraulic pump, etc., are
contained inside the shock absorber. It uses road
inputs (bumps, stops, starts, turns, acceleration,
deceleration, etc.) to activate pumping, which results
in the extension and compression of the shock
absorber.
REMOVAL - SHOCK ABSORBER
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Support the rear axle of the vehicle using 2
jackstands positioned at the outer ends of the axle.
NOTE: If the shock absorber lower mounting bolt
deflects upward during removal, raise axle by
adjusting the support jack. If the lower shock
absorber bolt deflects downward during removal,
lower the axle by adjusting the support jack.
(3) Remove the shock absorber lower mounting
bolt.
(4) While holding shock absorber, remove the
shock absorber upper mounting bolt and shock
absorber.
