GENERAL
Jeep vehicles are equipped with semi-elliptic leaf
springs and dual-action hydraulic shock absorbers at
front and rear. A front axle stabilizer bar is standard on
Cherokee, Wagoneer, Truck models and CJ and Scram
bler models with the molded hard top. A front stabilizer
bar is optional on all other CJ and Scrambler models.
Front and rear suspension springs are mounted para
llel to the frame side rails. The forward end of the front
springs and the rear end of the rear springs are attached
to the frame by pivoting shackles. The opposite spring
ends are attached to the frame by fixed pivot bolts. All
spring ends have silent-block type rubber bushings
which do not require lubrication.
The front springs are mounted below the axle on all
Jeep vehicles. CJ and Scrambler models use multi-leaf
front springs (fig. 2N-1). Cherokee, Wagoneer, and
Truck models use tapered-leaf or multi-leaf front
springs (fig. 2N-2).
The multi-leaf rear springs used on CJ and Scrambler
models are mounted below the axle (fig. 2N-3).
The rear springs used on Cherokee, Wagoneer, and
Truck models are either multi-leaf or tapered-leaf
springs and are mounted above the axle (figs. 2N-4 and
2N-5).
The leaf springs on all Jeep models are attached to the
axle by U-bolts and tie plates and are positioned on the
axle by spring saddles welded to the axle tubes. Spring
center bolts and spring clips are used to align and hold
the spring leaves in position. If the vehicle is used for
severe, off-road operation, the springs should be exam
ined periodically for broken or shifted leaves, loose or
missing clips, and broken center bolts.
Squeaking noises can be generated when movement
between the spring bushings and metal parts occurs.
This noise can usually be eliminated by tightening the

The spring eye bushings do not require any typ
lubrication. Do not attempt to eliminate bushing n
by lubricating them. Grease and mineral oil-base 1
cants can cause deterioration of the bushing rubber
SUSPENSION JOUNCE AND WINDUP BUMPERS
A front axle windup bumper is used on CJ and Sc:
bier models only. The bumper consists of a star
bracket with a rubber bumper attached to it (fig. 2
The bracket is attached to the inner side of the
frame rail adjacent to and just above the front
housing. During severe operation when extreme s;,
movement and front axle travel occurs, the bumper
tacts a pad on the front axle housing to prevent e:
sive housing movement.
All models are equipped with frame-mounted jo
bumpers located at the front and rear of the ve
suspension. The bumpers are attached to the unde:
of the frame rails and are positioned over and in
with the axle tubes.
SHOCK ABSORBERS
The hydraulic, dual-action shock absorbers use
Jeep vehicles are designed to control suspension st.
movement. The shock absorber upper ends arc atta
to brackets located on the frame rails. The lower
