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
RUW34DLF000701
The transfer case is used to provide a means of providing power flow to the front axle. The transfer case also provides
a means of disconnecting the front axle, providing better fuel economy and quieter operation when the vehicle is driven
on improved roads where four wheel drive is not required. In addition, the transfer case provides an additional gear
reduction when placed in low range, which is useful when difficult off-road conditions are encountered.
Use the 4WD switch on the center cluster panel to select the drive range. The 4WD indicator lamp is n when 4WD is
selected.

material are removed from the surfaces of ever
y
part. Apply compressed air to each oil feed port and
channel in each case half to remove an
y
obstructions or cleaning solvent residue.
Inspection and Repair (Transfer Case
Assembly)
When wear, damage, or any other defects are observed
during the inspection, the part or parts must be repaired

wall of the transf er c over or the c hain is so s lack that
a skipped engagement occurs between the chain
and sprocket, replace the chain.
Sprocket
Check whether the sprocket tooth surface is
exces sively worn or dam aged, and there is evidence
of burrs, chipping, wear, or damage on the gear
spline. Remove minor flaws or scratches with oil
stone. If excessive wear or damage is observed,
replace the part.
If excessive wear or damage is observed on the
sprocket inside sliding surface, replace the part.
Gear
Check whether the gear tooth surface is excessivel
y
worn or damaged, and there is evidence of burrs,
chipping, wear, or damage on the gear spline.
Remove minor flaws or scratches with oil stone. I
