4. Remove bolt, nut and washer (Front axle side).
5. Remove bolt, nut and washer (Transfer side).
6. Remove front propeller shaft.
NOTE: When removing, installing or carring the front
propeller shaft, be sure to wrap a piece of cloth around the
part of the boot with which fittings may interfere so that the
boot can be protected. The boot may be damaged if
bending force is applied to the constant velocity joint of
the shaft.

Installation
NOTE: Never install the shaft assembly backwards.
Completely remove the black paint from the connecting
surface of flange coupling on each end of propeller shaft.
Clean so that no foreign matter will be caught in between.
1. Align the mark which was applied at removal. Install
front propeller shaft and tighten the bolts to the
specified torque.
Torque: 63 N´m (46 lb ft)
2. Install the exhaust and transfer protectors.
Constant Velocity Joint
NOTE: L J a n d B J constant velocity joints are
unremovable types. Check the joint for play and the boot
for damage, wear, and leak of grease. If abnormality is
found, replace propeller shaft as an assembly.

Front Axle Flange Run-out
1. Set a dial gage at right angle near the outer
circumference of the flange face and check the
run-out of the flange face.
Limit: 0.15 mm (0.006 in)

2. Set a dial gage at right angle near the inner
circumference and check the run-out of the flange.
Limit: 0.15 mm (0.006 in)

3. If vibration is felt during the 4H AUTO drive, disconnct
the propeller shaft at the front axle. Reinstall the
propeller shaft at 60
, 120
, 180
, 240
, and 300

and conduct test drive in each position and check if
there is vibration.

Removal
1. Raise the vehicle on a hoist.
NOTE: Apply alignment marks on the flange at the rear
propeller shaft both front and rear side.
2. Remove transfer side bolt, nut and washer (except
spline yoke type).
3. Remove rear axle side bolt, nut and washer.
4. Remove rear propeller shaft.
NOTE: Plug the hole of the transmission rear end to
prevent oil leakage (spline yoke type only).
Installation
NOTE: Never install the shaft assembly backwards.
Never insert bar between yoke lugs when tightening or re-
moving bolts.
Completely remove the dust or foreign matter from the
connecting surface of flange coupling on each end of the
propeller shaft.

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.

axle/transfer case system.The drive axles are completely flexible assemblies,
consisting of inner and outer constant velocity (CV) drive
shaft joints connected by an axle shaft.
For description of front propeller shaft and universal joint,
refer to
