DESCRIPTION AND OPERATION
FRONT SUSPENSION DESCRIPTION
An independent Mc Pherson Strut type front sus-
pension is used on these vehicles. Vertical shock
absorbing Mc Pherson Struts attach to the top of the
steering knuckle and to the front strut tower. This
interconnection between the steering knuckle and the
body of the vehicle, provides for the correct steering
knuckle position. This steering knuckle position pro-
vides for the correct front Caster and Camber set-
tings for the vehicle, at the time the vehicle is
designed.
Lower control arms are attached inboard to the
cast aluminum front suspension cradle and outboard
to the bottom of the steering knuckle. Attachment of
the lower control arm to the steering knuckle is done
through a ball joint in the lower control arm.
During steering maneuvers, the strut and the
steering knuckle (through the ball joint and a pivot
bearing in the strut's upper retainer) turn as an
assembly.
SUSPENSION CRADLE (CROSSMEMBER)
This vehicle uses a one piece cast aluminum cradle
for the front suspension. The cradle is used as theattaching points for the lower control arms, stabilizer
bar and steering gear. The cradle also has the power
steering hoses and the chassis brake tubes attached
to it.
The cradle is mounted to the front frame rails at
four points, two on each side of the vehicle. The cra-
dle is isolated from the body of the vehicle using four
isolators, one located at each mounting bolt location.
WARNING: If a threaded hole in the suspension
cradle needs to be repaired, only use the type of
thread insert and installation procedure specified
for this application.
The threaded holes in the cradle that are
used for attachment of the lower control arm
rear bushing retainer, power steering hose and
chassis brake tubes can be repaired. The repair
is done by the installation of a Heli-Coilt
thread insert which has been specifically devel-
oped for this application. Refer to the Mopar
Parts Catalog for the specified Heli-Coil thread
insert to be used for this application. The pro-
cedure for installing the Heli-Coiltthread
insert is detailed in the Service Procedures sec-
tion in this group of the service manual.

GENERAL INFORMATION
REAR SUSPENSION
The rear suspension design on this vehicle uses
leaf springs and a tube and casting axle (Fig. 1) and
(Fig. 2). It is designed to handle the various load
requirements of the vehicle. The leaf springs used on
the rear suspension of this vehicle are of either a
mono-leaf or multi-leaf design.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 leaf
springs but does not use isolator bushings between
the rear axle and the leaf springs.
Fig. 1 Front Wheel Drive Rear Suspension
2 - 38 SUSPENSIONNS
The rear suspension used on the front wheel drive
commercial version of this vehicle is unique to this
application. The rear axle is mounted to the rear leaf
springs as on the non-commercial application of this
vehicle but does not use any isolators between the
spring and the axle. The leaf spring used on the com-
mercial version of this vehicle is a multi-leaf spring
but is a unique design for the commercial applica-
tion.
The rear leaf spring shackle angles provide
increasing suspension rates as the vehicle is loaded.
This provides a comfortable unloaded ride and also
ample rear suspension travel when the vehicle is
loaded.
A new type of load-leveling shock is available. The
self leveling shock absorbers are a self-contained
vehicle leveling system and shock absorber combined.
The shock absorbers are mounted at an angle, paral-
lel to the springs and forward at the top. This design
provides greater stability in addition to controlling
ride motion.
The rear wheel bearings used are similar to the
bearings used in the front wheels. The bearings are
permanently sealed and require no maintenance. The
bearing and hub are serviced as an assembly. For
service procedures, refer to Group 5, Brakes.DESCRIPTION AND OPERATION
REAR WHEEL ALIGNMENT
Alignment adjustment is not required. The rear
axle alignment settings are preset at the factory and
therefore no alignment is necessary.
REAR TRACK BAR
On front wheel drive applications of this vehicle
that are equipped with single leaf rear springs a
track bar (Fig. 3) is used on the rear axle.
The track bar connects the rear axle to the frame/
body of the vehicle. The track bar is isolated from the
body of the vehicle by an isloator bushing located in
each end of the track bar.
The track bar (Fig. 3) prevents excessive side to
side movement of the rear axle. The track bar is used
to keep the location of the axle in the correct position
for optimum handling and control of the vehicle.
STABILIZER BAR
The stabilizer bar (Fig. 4) interconnects both sides
of the rear axle and attaches to the rear frame rails
using 2 rubber isolated link arms.
Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
to reduce body roll.
Fig. 2 All Wheel Drive Rear Suspension
NSSUSPENSION 2 - 39
GENERAL INFORMATION (Continued)
Attachment to the rear axle tube, and rear frame
rails is through rubber-isolated bushings. All parts
are serviceable, and the stabilizer bar to axle bush-
ings are split for easy removal and installation. The
split in the bushing should be positioned up when
the stabilizer bar is installed on the vehicle.
The 2 rubber isolated link arms are connected to
the rear frame rails by brackets. These brackets are
bolted to the bottom of the frame rails.
SHOCK ABSORBERS (REAR LOAD LEVELING)
A new type of load-leveling shock is available. The
self leveling shock absorbers are a self-contained
vehicle leveling system and shock absorber combined.
It does not require an external compressor, hoses,height leveling sensors, etc. It uses road inputs
(bumps, stops, starts, turns, acceleration, decelera-
tion, etc.) to activate pumping, which is just the
extension and compression of the shock absorber. On
the outside, it looks like a larger than normal shock
absorber. Internally, it consists of a hydraulic pump
and gas-spring cushion for leveling, as well as the
normal shock absorbing mechanism. All the height
leveling sensors, pump, etc., are contained inside the
shocks. The shocks are mounted at an angle, parallel
to the springs and forward at the top. This design
provides greater stability in addition to controlling
ride motion. These new load-leveling shock absorbers
use longer fasteners than the standard shock absorb-
ers, although the fasteners are longer, the torque
specifications are the same.
