PROPELLER SHAFT 4A-25
401RS027
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 shaf
t
assembly.
Standard: 0.3 mm (0.012 in)
Limit: 0.5 mm (0.02 in)
401RS009
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)
401RS010
Play in Universal Joint
Limit: Less than 0.1 mm (0.004 in)
401RS011
Reassembly
1. Install spider to flange yoke. Be sure to install the spider by
aligning the setting marks made during disassembly.
2. 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)

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.

4. Align setting marks (1) and join the yokes.
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).

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 REFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFE
R
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 prope
r
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 o
r
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 specification.
Following these instructions can help you avoid
damage to parts and systems.
