spider gears if they have chipped, pitted, or missing teeth, or if the
inside diameter
is excessively
worn.
Replace
the differential side
gears if they have broken, chipped, pitted, or excessively worn teeth
or splines.
Insert a new axle shaft in the differential side gear. If the backlash
is excessive, replace the differential side gear. Replace the differential
spider gear thrust washer if excessively worn.
(1) DIFFERENTIAL
BEARING
REPLACEMENT.
Remove
the bearing from either the drive gear assembly or the differential
case, using a puller that applies pressure to the inner race (fig. 39).
To install a new bearing on the drive gear assembly or differential
case, place either part in a press and, with a driver that applies
pressure to the inner race evenly, press the bearing on the case until
it is firmly seated on the shoulder of the case.
c. Drive Pinion
Assembly.
The drive gear assembly and the
pinion
gear are furnished
only in matched
sets, and if either is
damaged, both must be replaced. Replace the drive pinion sleeve if
it is cracked. Replace the drive pinion bearing cups in the sleeve if
they are cracked, pitted, corroded, or discolored due to overheating
(subpar. (1) below). Replace the drive pinion if the gear has chipped,
pitted, or missing teeth, or if the shaft has damaged
threads
or
splines. Replace the pilot bearing inner race at the end of the drive
