Differential Carrier Overhaul
(Forward and Rear Axles)
Disassemble Differential Carrier
(with power divider removed)
NOTE:
If the gear set is to be
reused, check tooth contact pattern
and ring gear backlash before
beginning disassembly. Best
overhaul results are obtained when
used gearing is adjusted to
run in
established wear patterns. Omit
this step if the gear set is to be
replaced.
When reusing the
gear set, remove
the left-hand bearing cap, adjuster
and lock as a unit. This will help
return the gear set to its original
adjustment during reassembly.
1.
Mount the differential carrier in
a repair stand.
NOTE:
For easier disassembly,
loosen but do not remove pinion
self-locking nut. When forward
axle pinion is equipped with
slotted nut, remove roll pin with
a pin punch then loosen nut.
