The links attach to the vehicle with bolts and bushings
at their inner pivot points and to the steering knuckle,
which is part of the front wheel spindle, at their outer
points.
The knuckle is mounted to the upper and lower links
each of which has a ball joint to permit pivoting of the
knuckle for steering operations. The hub is supported
in position on the knuckle spindle by means of the two
bearings and the rotor is mounted on the hub.
The front suspension is an independent type utilizing
torsion bar springs (4 ×4, 4 ×2 (High ride suspension))
and coil springs (4 ×2 (except High ride suspension)).
The torsion bar spring has splines on each end. Height
control is provided on the third crossmember. Both the
upper and lower links are pressed steel and the torsion
bar is supported at the ends by lower link in front and by
height control arm in rear.

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

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/GM will indicate those fasteners that require
replacement after removal. ISUZU/GM will also
indicate the fasteners that require thread lockers o
r
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.
