Carrier Assembly
Carrier As
sembly
Remove Wheel Differential (All Standard
Models)
Note: If gear set is to be reused, check tooth contact pattern
and ring gear backlash before disassembling differential
carrier. When checking backlash, a yoke or helical gear
must be installed and torqued to get an accurate reading.
Best results are obtained when established wear patterns
are maintained in used gearing. Omit this step if the gear
set is to be replaced.
1. Mount differential carrier in repair stand.
Note: For easier disassembly, loosen but do not remove pinion
(self-locking) nut. Forward axle pinion is equipped with
slotted nut, remove roll pin with a pin punch then loosen
nut.
2. Punch mark bearing caps. If reusing gear set, also
punch mark bearing adjusters for reference during
assembly.
3. Cut lockwire. Remove capscrews, flat washers and
bearing caps. Back off bearing adjusters and remove
adjusters and bearing cups.
4. Using a chain hoist, lift ring gear and differential as-
sembly out of carrier.
