Forward Assembly
Disassemble Wheel Differential (All Standard Models)
Note: Omit this step if the gear set is to be replaced. 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.
1. Mount differential carrier in repair stand.
Note: For easier disassembly, loosen but do not remove pin-
ion (self-locking) nut. Forward axle pinion is equipped
with slotted nut, remove roll pin with a pin punch then
loosen nut.
2. If reusing gear set, also punch mark bearing adjust-
ers for reference during assembly.
3. Remove cap screws, 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
assembly out of carrier.
