CAUTION
NOTE: On the pinion mate gear, look for nicks,
chips or visible damage to the gear teeth. Inspect
the back gear face for a groove or other visible
signs of damage (Figure 45). This is where the
pinion mate thrust washer rides. The surface will
be shiny and smooth if there is no damage.
Check the thrust washers for grooves or damage
on both sides of the washer. Also, look to see if
the washer is bent or part of the washer is
missing at the spot where the pinion mate shaft
passes through the washer.
NOTE: This surface will be shiny and smooth if
there is no damage. Look at the side gear thrust
washer for grooves or visible damage. If any
damage to the side gear or thrust washer is
noted, they must be replaced.
NOTE: Also, be sure to check for damage in the
following areas: the ring gear mounting surface
for nicks and high spots; the bearing trunnion for
grooves or damage caused by the bearing
spinning on the trunnion
7. Surface nicks can be stoned or filed off.
NOTE: If the bearing fell off the trunnion and did
not need to be pressed off, the differential case
must be replaced.
8. Check the machined areas where the pinion
mate and side gear thrust washers sit (Figure
47).
If the shaft took out part of the
washer during assembly, the hole will look
distorted and not round. If this is the case, the
thrust washer is damaged and must be replaced.
If any of these parts look damaged, they should
be replaced as well. All damaged parts must be
replaced in sets.
6. Take the side gears out of the case and look
for nicks, chips, or other signs of damage to
the teeth on the side gears. (Figure 46) Check
the back face of the side gear for a groove or
visible damage.
