Inspection and Repair
Make necessary correction or parts replacement if wear,
damage, corrosion or any other abnormal conditions are
found through inspection.
Check the following parts:
1. Ring gear, pinion gear
2. Bearing
3. Side gear, pinion gear, cross pin
4. Differential cage, carrier
5. Thrust washer
6. Oil seal
Ring gear replacement:
1. The ring gear should always be replaced with the
drive pinion as a set.
2. Clean the ring gear threaded holes to remove the
locking agent.
3. When installing the ring gear, apply LOCTITE 271 or
equivalent to all the threaded area and half of the
unthreaded area of the bolt.
4. Discard used bolts and install new ones.
Torque: 108 Nꞏm (11.0kgꞏm/80 lb ft)5. Tighten the fixing bolts in a diagonal sequence as
illustrated.

Service Precaution
WARNING: IF SO EQUIPPED WITH 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, 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
c l a m p i n g f o r c e , a n d m a y d a m a g e t h e f a s t e n e r. W h e n
you install fasteners, use the correct tightening
sequence and specification. Following these
instructions can help you avoid damage to parts and
systems.
