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 to 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, REFE
R
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, o
r
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.
