3. Make sure of proper position for reinstallation by
applying setting marks, then remove spider with
grease fitting.
Inspection and Repair
Make necessary correction or parts replacement if wear,
damage, corrosion or any other abnormal condition is
found through inspection.
NOTE: When any part of the journal assembly (spider,
needle roller bearing, grease fitting) requires
replacement, be sure to replace the entire assembly.
Check the following parts for wear, damage, noise or any
other abnormal conditions:
1. Spider
2. Needle roller bearing
3. Yoke
4. Flange
Outside Diameter of Spider Pin
Standard: 17.00 mm (0.669 in)
Limit: 16.90 mm (0.665 in)
401RS007
Propeller Shaft Run-out
Support the ends of the propeller shaft on V-blocks (2)
and check for run-out by holding the probe of a dial
indicator (1) in contact with the center part of the shaft. If
the amount of run-out is beyond the standard value for
assembly, correct with a bench press or replace the shaft
with a new propeller shaft assembly .
Standard: 0.3 mm (0.012 in)
Limit: 0.5 mm (0.02 in)
401RS008
Play in Splines in Normal Direction of
Rotation
Check the amount of play between the sleeve yoke (1)
and the propeller shaft spline (2) in the direction of
rotation, using a pointed feeler gauge.
Standard: 0.073 – 0.156 mm (0.003 – 0.006 in)
Limit: 0.3 mm (0.012 in)

Universal Joint Reassembly
1. Install spider to flange yoke. Be sure to install the
spider by aligning the setting marks made during
disassembly.
2. Before installing needle roller bearing, apply a
molybdenum–disulfide grease or a multi–purpose
type grease NLGI No. 2 to inside of the bearing cap.
Grease Amount: Approx. 1.2 g (0.042 oz)
401RS011
3. Using either a mallet (or copper hammer) or a press,
install the needle roller bearing into the yoke so that
the snap ring can be installed in its groove.
CAUTION: The needle roller bearing cannot be
installed smoothly if it is set at an incorrect angle
with the flange and excessive hammering will
damage the needle roller bearing.
401RS012
4. Align setting marks (1) and join the yokes.
NOTE: Assemble the spider and spline yoke so that their
grease fittings are arranged on the same side.
401RS028
5. Install snap ring.
NOTE: Discard used snap rings and install new ones.
When the bearing cap is in position, select and attach a
snap ring of suitable thickness so that the end play of the
spider pin is held within 0.1 mm (0.004 in).
Snap ring thickness and identification color
1.5 mm (0.059 in): Blue
1.545 mm (0.061 in): White
1.59 mm (0.063 in): Yellow
1.635 mm (0.064 in): Green
1.68 mm (0.066 in): Not colored
NOTE: Be sure to use snap rings of the same thickness
on both sides.

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.
