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.

General Description

The rear suspension is a 5-link, coil spring type
suspension with a stabilizer bar,  consisting of two
trailing links, two upper links, lateral rod, shock
absorber, and stabilizer.   In this suspension, the links
are specially arranged to enable the rear axle to move
freely,  thereby expanding suspension stroke, reducing
friction, and improving lateral rigidity and roll control.
All these result in improved stability, riding comfort, and
rough road maneuverability.
Each link connects the axle housing with the frame
through a runner bushing.   The axle housing is
supported by the trailing links and upper links
longitudinally and by the lateral rod latitudinally.
