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.

Diagnosis

Since the problems in steering, suspension, wheels and 
tires involve several systems, they must all be 
considered  when diagnosing a complaint. To identify 
the symptom,  always road test the vehicle first. 
Proceed with the following preliminary inspections and 
correct any defects which are found.

1. Inspect tires for proper pressure and uneven wear.

2. Raise vehicle on a hoist, then inspect front and rear 

suspension and steering linkage for loose or 
damaged parts.

3. Spin the front wheels.  Inspect for out-of-round tires, 

out-of-balance tires, loose and/or rough wheel 
bearings.
