Assemble
NOTE: Thoroughly clean and inspect all parts
before reassembly. Apply a small
amount of differential oil to all gears
and bearings before reassembly.
NOTE: Depending on your vehicle config-
uration, the rear pinion pilot bearing is
not required and may not be installed.
NOTE: If the ring and pinion gear set is to be
replaced then the shims for the pinion
housing may have to be adjusted.
Refer to section
Selecting the
Pinion Housing Shim
for
information on adjusting the shim.
NOTE: Most of our gear sets are non-hunting
or semi-hunting gears. With this type
of gear the pinion and ring gears must
be aligned correctly. There will be two
teeth marked on the ring gear and one
tooth marked on the pinion gear. The
one tooth on the pinion gear must be
installed so that it is between the two
teeth on the ring gear. The gear ratios
are; 2.50, 2.70, 2.75, 3.25 and 3.00.
Pinion housing
1. If the rear pinion bearing was removed, install a new bearing.
2. Install the bearing races into the pinion housing.
3. Place the pinion gear into the 3rd member.
4. Install the pinion housing onto the 3rd member.
5. Install the pinion bearing spacers, shims and front bearing.
6. Install a spacer on the pinion shaft so that the pinion nut can be installed and tightened.
7. While rotating the pinion shaft, tighten the pinion nut to 100 ft-lbs.
8. Check the torque required to rotate the shaft. If the torque is not between 6 -10 in-lbs. then the
bearings must be re-shimmed. Add or subtract shims as required until the torque is within
specifications.
