REAR FINAL DRIVE ASSEMBLY
3. Measure the side gear endplay following the procedure below,
and select the appropriate side gear thrust washers.
●Using a thickness gauge, measure the clearance between
side gear back and the differential case at 3 different points,
while rotating the side gear. Average the 3 readings, and
select the appropriate side gear thrust washer so that the
mean value is within specifications below. (Measure the clear-
ance of the other side as well.)
CAUTION:
●Before measurement, place differential case straight up
so that side gear to be measured comes upward. To pre-
vent the side gear from tilting, insert thickness gauges
with the same thickness from both sides.
●Select a side gear thrust washer for right and left individ-
ually.
4. Assemble the selected side gear thrust washer to the differential case.
5. Using a pin punch, drive a lock pin into the pinion mating shaft.
CAUTION:
Do not reuse the lock pin.
6. Using a drift, press a side bearing inner race into the differential
case.
7. Apply locking sealant (Thread lock super 1303 or equivalent) onto the thread of the drive gear.
CAUTION:
The drive gear back, threaded holes, and drive gear bolts shall be cleaned and decreased suffi-
ciently.
8. Assemble the drive gear to the differential case, and tighten it with drive gear bolt. Side gear endplay standard:
0.2 mm (0.008 in) or less. Every gear shall rotate
smoothly with no abnormal feeling of drag.

9. Apply differential oil to the side bearings, and assemble new side bearing adjusting shims (2 pieces for
one side) with the same thickness as the ones installed prior to disassembly or re-install the old ones, with
a side bearing outer race to the differential case.
If the side bearing adjusting shims have been already selected, use them.
10. Fit a drift to the right and left side bearing adjusting shims indi-
vidually. Compress differential case assembly and side bearing
to install the carrier case assembly to differential case assembly.
CAUTION:
●A drift shall be placed on the center of the adjusting
shims.
●The pressure shall be as low as possible to install the
carrier case assembly into the differential assembly. The
maximum pressure shall be 1 ton.
●If the adjusting shims are installed by tapping, the carrier
case may be damaged. Avoid tapping.
11. Install a dummy cover set, check and adjust the backlash, drive gear back runout, tooth contact, and over-
all preload torque. Refer to RFD-15, "
Inspection Before Disassembly" .
12. Remove dummy cover set.
13. Apply sealant (Three bond 1217 or the equivalent) around the carrier case mounting surface on the rear
cover.Refer to
CAUTION:
Remove old sealant on the mounting surface, then remove any moisture, oil, and foreign material
on the application and mounting surfaces.
14. Fit a drift to the right and left side bearing adjusting shims indi-
vidually. Compress differential case assembly and side bearing
to install the rear cover.
CAUTION:
●A drift shall be placed on the center of the adjusting
shims.
●The pressure shall be as low as possible to install the
rear cover. The maximum pressure shall be 10kN (1 ton,
1.1US ton, 1.0 Imp ton)
●If the rear cover is forced in by tapping, the rear cover
may be damaged by the adjusting shims. Avoid tapping.
15. Tighten rear cover mounting bolts to the specified torque.
16. Using a drift, drive the oil seal until it becomes flush with the
case end.
CAUTION:
●Oil seals are not reusable. Never reuse them.
●Apply multi-purpose grease onto the oil seal lips, and dif-
ferential oil onto the circumference of the oil seal.
17. Check overall preload torque. Refer to RFD-15, "
OVERALL PRELOAD TORQUE" .
