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 UNNECESSARY 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/GM will call out those fasteners that require
a replacement after removal. ISUZU/GM 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 specifications.
Following these instructions can help you avoid
damage to parts and systems.

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)

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)
