Inspection and Repair
Drive Plate
If the frictional surface shows signs of damage due to
excessive heat, the drive plate and pulley should be
replaced.
Pulley Assembly
Check the appearance of the pulley assembly. If the
frictional surface of the pulley shows signs of excessive
grooving due to slippage, both the pulley and drive plate
should be replaced. The frictional surfaces of the pulley
assembly should be cleaned with a suitable solvent
before reinstallation.
Coil
Check coil for loose connector or cracked insulation.
Installation
1. Install field coil.
Align the located portion (1) of the field coil and
compressor.

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 follow-
ing 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.
General Diagnosis
ConditionPossible causeCorrection
Vehicle PullsMismatched or uneven tires.Replace tire.
Tires not adequately inflated.Adjust tire pressure.
Broken or sagging springs.Replace spring.

Loose, bent or broken front or rear
suspension parts.Tighten or replace the appropriate
suspension part(s).
Faulty shock absorbers.Replace shock absorber.

POWER±ASSISTED STEERING SYSTEM
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted
conveniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be locked to prevent theft of
the vehicle.The column can be disassembled and reassembled.
However, to insure the energy absorbing action, use only
the specified screws, bolts and nuts as designated, and
tighten them to the specified torque.
Handle the column with care when it is removed from the
vehicle. A sharp blow on the end of steering shaft or shift
lever, or dropping the assembly could shear or loosen the
fasteners that maintain column rigidity.
Power Steering System Test
Test Procedure
C02RW001
Legend
(1) Fluid Reservoir(2) Power Steering Unit
(3) Power Steering Pump
Test of fluid pressure in the power steering system is
performed to determine whether or not the oil pump and
power steering unit are functioning normally.
The power steering system test is used to identify and
isolate hydraulic circuit difficulties. Prior to performing
this test, the following inspections and corrections, if
necessary, must be made.
Inspect pump reservoir for proper fluid level.
Inspect pump belt for proper tension.
Inspect pump driver pulley condition. 1. Place a container under the pump to catch the fluid
when disconnecting or connecting the hoses.
2. With the engine NOT running, disconnect the
pressure hose at the power steering pump and install
power steering tester J-29877-A. The gage must be
between the shutoff valve and pump. Open the
shutoff valve.
3. Check the fluid level. Fill the reservoir with power
steering fluid, to the ªFullº mark. Start the engine,
then turn the steering wheel and momentarily hold it
against a stop (right or left). Turn the engine off and
check the connections at tester for leakage.

1. Check and adjust the tire inflation pressures.
2. Park the vehicle on a level ground and move the front
of the vehicle up and down several times to settle the
suspension.
3. Make necessary adjustment with the adjusting bolt on
the height control arms.
Trim height: 119 + 5 mm (4.69 + 0.2 in)
Caster Adjustment
The caster angle can be adjusted by means of the caster
shims (1) installed between the chassis frame (2) and
fulcrum pins.
Caster angle: 230' + 1
CAUTION: Left and right side must be equal within
30'.
450RW006
450RS002
NOTE: Difference of the caster shim front/rear thickness
should be 3.6 mm (0.142 in) or less. Overall thickness of
caster shim and camber shim should be 10.8 mm
(0.425 in) or less.
Tighten the fulcrum pin bolt to the specified torque.
Torque: 152 N´m 112 ( lb ft)
Camber Adjustment
The camber angle can be adjusted by means of the
camber shims (2) installed in position between the
chassis frame (1) and fulcrum pins
Camber angle: 0 + 30'
King pin inclination: 1230' + 30'
CAUTION: Left and right side must be equal within
30'.
