(2) Inspect hypoid pinions and gears for wear and damage. Replace
gears that are worn or damaged.
! CAUTION
A thrust washer, differential side gear and pinion gear are machined
as a matched set. When you replace any of these parts, you must
install a new matched set. Do not mix old and new parts. Damage to
components can result.
(3) Inspect the following main differential assembly parts for wear or
stress. Replace parts that are damaged.
•
Inside surfaces of both case halves
• Both surfaces of all thrust washers
•
The four trunnion ends of the spider or cross
• Teeth and splines of both differential side gears
•
Teeth and bore of all differential pinions
(4) Inspect axle shafts for wear and cracks at the flange, shaft and
splines. Replace the axle shafts, if required.
(5) Inspect the breather.
.
a. Remove the breather from the axle housing.
b. Clean the breather. If the breather remains dirty after cleaning,
replace the breather.
c. Apply compressed air to the breather. If compressed air does not
pass through the breather, replace the breather.
d. Install the breather in the axle housing.
8. REPAIR OR REPLACE PARTS
NOTICE
Threads must be without damage and clean so that accurate adjust-
ments and correct torque values can be applied to fasteners and
parts.
(1) Replace any fastener if corners of the head are worn.
(2) Replace washers if damaged.
(3) Replace gaskets, oil seals or grease seals at the time of axle or carrier
repair.
(4) Clean parts and apply new silicone gasket material where required
when axle or carrier is assembled.
(5) Remove nicks, mars and burrs from parts with machined or ground
surfaces. Use a fine file, India stone, emery cloth or crocus cloth.
(6) Clean and repair threads of fasteners and holes. Use a die or tap of
the correct size or a fine file.
