Torque is transmitted from the transmission to the axle
through the propeller shaft and universal joint assembles.
All propeller shafts are the balanced tubular type. A
splined slip joint is provided in some drivelines.

Since the propeller shaft is balanced carefully,
welding or any other modification is not permitted.
Alignment marks should be applied to each propeller
shaft before removal.

Park, turn the engine off and apply the parking brake
to secure the vehicle.

Carefully attach the propeller shaft to the vise, do not
overtighten the vise when securing the propeller
shaft, this may cause deformation.

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 (TOD)
General Description
A04R200003
The Torque-On-Demand (TOD) is an
electronically-controlled torque-split 4-wheel drive
system with the following features.
Shifting Between High and Low Ranges
The shifting mechanism consists of the cam and shaft rail
assembly, the high/low shift motor and the encoder. The
encoder is built-in to the motor.
The encoder senses high/low range shift motor rotation
position and sends this data to the TOD control unit.
Based on this data, the TOD control unit adjusts motor
rotation speed or stops the motor.
The shifting between the high and low ranges using the
TOD switch only is possible. The vehicle must be stopped
or nearly stopped (vehicle speed less than 2 km/h (1.2
mph) and engine speed less than 1,500 rpm), the
automatic transmission selector level must be in the
neutral (N) position, and the brakes must be applied.
Electronically-controlled Wet-type Multiple
Disc Clutch
The clutch automatically provides the optimum drive
power to the front wheels of the vehicle in response to
varying road surface conditions when the vehicle is
operated in the TOD mode. The delivered power ranges
from 0% to 100% of power train output. Superior
operational stability is maintained over a wide range of
operating conditions.
Front Output Drive
Front output drive is provided by a chain. This reduces the
loud noise associated with 4-wheel drive operation.
Oil Pump Lubrication
An oil pump is used to lubricate the transfer. This ensures
stable multiple-disc clutch operation and maintains the
lubricating oil at a constant temperature.
