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.

TRANSFER CASE (STANDARD TYPE)

General Description

TRANSFER CASE (STANDARD TYPE)

4D1–3

A/T model

A07RW001

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.
A floor mounted shift lever is used to select the operating
range. When four wheel drive has been selected, the four
wheel drive indicator light is designed to come on when
the front axle has been engaged.
