• If the preload torque is below the preload val­
ues given above, continue tightening the nut in
small increments. Check the preload after each
tightening. Each tightening increases the bear­
ing preload by several pounds. If the bearing
preload is exceeded, the pinion will have to be
removed and a new collapsible spacer installed.
• Once the preload has been obtained, rotate the
pinion several times to make sure the bearings
are seated. Recheck the preload and adjust if
necessary.
8. Differential case. Refer to " Backlash Adjustment."
DIFFERENTIAL CASE ASSEMBLY
Install or Connect (Figure 1, 19 through 22)
Tools Required:
J 8107-3 Differential Side Bearing Removal Plug
J 8092 Driver Handle
J 29710 Differential Side Bearing Installer
1. Lubricate all parts with axle lubricant.
2. Side gear thrust washers (32) to the side gears
(33).
3. Side gears (33) to the differential case (27).
• Install the side gears on the same side as when
removed.
4. Pinion gears (31) to the differential without the pin­
ion thrust washers (30).
A. Install the pinion gears onto the side gears so
the holes in the pinion gears are 180 degrees
apart.
B. Rotate the pinion gears into place, and verify
the pinion gears line up with the pinion shaft
holes.
5. Pinion thrust washers (30).
• Rotate the pinion gears toward the differential
opening enough to slide in the pinion thrust
washers.
• Make sure the mating surfaces of the differen­
tial case and ring gear are clean and burr free.
6. Ring gear (15) to the differential case (27).
A. Thread two left-hand threaded bolts into the ring
gear on opposite sides.
B. Place the ring gear onto the case, and align the
holes in the case with the bolts (figure 19).
C. Press the ring gear onto the case far enough to
start the bolts using J 8107-3 to protect the
differential from the press ram (figure 20).
NOTICE: Refer to "Notice" on page 4B3-1.
7. Ring gear bolts (26).
• Tighten the ring gear bolts alternately, and in
stages gradually pulling the ring gear onto the
differential case.
