DISASSEMBLY AND ASSEMBLY (Continued)

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.
