'\f CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were removed.
If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct
part
number fastener is not available, a fastener of equal size and strength (or stronger) may be used.
Fasteners
that are not reused, and those requiring thread locking compound, will be called out. The correct
torque value must be used when installing fasteners that require it. If the above conditions are not
followed, parts or system damage could result.
Refer to section 3A in this manual for the wheel alignment procedure.

GENERAL DESCRIPTION
The front suspension is designed to allow each wheel
to compensate for changes in the road surface level
without greatly affecting the opposite wheel. Each
wheel is independently connected to the frame by a
steering
knuckle, ball joint assemblies, and upper and
lower control arms. The front wheels are held in
proper relationship to each other by two outer track
rods
which are connected to steering arms on the
knuckles and to a center track rod.
All models have a front suspension system consisting
of control arms, stabilizer bar, shock absorber and a
torsion bar. The front end of the torsion bar is
attached
to the lower control arm. The rear of the
torsion bar is mounted into a height control arm at the
crossmember. Vehicle trim height is controlled by
adjusting this arm.
Shock absorbers are
mounted between the brackets
on the
frame and the lower control arms. The lower
portion of each shock absorber is attached to the
lower control arm by a bolt and nut. The upper portion
of each shock absorber extends through a frame
bracket and is secured with two rubber bushings,
three retainers and a nut.
Ball joint assemblies are bolted to the outer end of the
upper and lower control arm and are attached to the
steering
knuckle by nuts and cotter pins.
The
inner ends of the upper control arm have pressed
in bushings.
Bolts, passing through the bushing,
attach the control arm to the frame. The inner ends of
the lower control arm are attached to the frame by
bolts passing through the bushings, which are
pressed in the frame.
Side
roll of the front suspension is controlled by a
spring steel stabilizer bar. It is mounted in rubber
bushings, which are held to the crossmember by
brackets. The ends of the stabilizer bar are connected
to the lower control arms by links.
