Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.
CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.
3C–2
FRONT SUSPENSION
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 tie-rods which are
connected to steering arms on the knuckles, and to a
steering unit.
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.
The upper portion of each shock absorber extends
through a frame bracket and is secured with two rubber
bushings, two 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.
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.
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 frame by brackets. The ends of the
stabilizer bar are connected to the lower control arms by
links.
