Installation of Differential Assembly
1. Assemble new side gear thrust washers with the same thickness as the ones installed prior to disassem-
bly or reinstall the old ones on the side gears.
2. Assemble the side gears, side gear thrust washers, pinion mate gears, and pinion mate thrust washers to
the differential case, and temporarily assemble the pinion mate shaft.
3. Measure the side gear end play 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.)
*: Always check with the Parts Department for the latest parts information.
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 individually.
4. Assemble the selected side gear thrust washer to the differential case.Tool number : ST35271000

5. Using the pin punch, drive a lock pin into the pinion mating shaft.
CAUTION:
Do not reuse the lock pin.
6. Using the suitable drift, press a side bearing inner race into the
differential case.
CAUTION:
Do not reuse the side bearing inner race.
7. Apply locking sealant 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. Refer to RFD-16,
"Components" .
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.
CAUTION:
Do not reuse the side bearing outer race.
10. Fit the suitable drifts to the right and left side bearing adjusting
shims individually. Compress differential case assembly and
side bearing to install the carrier case assembly to differential
case assembly.
CAUTION:

The 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-17, "
Pre-Inspection" .
12. Remove dummy cover set.

13. Apply a continuos bead of sealant around the carrier case mat-
ing surface on the rear cover as shown in the figure. Overlap
both ends of the bead for at least 3 mm (0.12 in).
CAUTION:
Remove old sealant on the mounting surface, then remove
any moisture, oil, and foreign material on the application
and mounting surfaces.
14. Fit the suitable drifts to the right and left side bearing adjusting
shims individually. Compress differential case assembly and
side bearing to install the rear cover.

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionEDS0005P

When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.

Oil will shorten the life of rubber bushes. Be sure to wipe off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.

After installing removed suspension parts, check wheel alignment and adjust if necessary.
Observe the following precautions when disassembling and servicing drive shaft.

Perform work in a location which is as dust-free as possible.

Before disassembling and servicing, clean the outside of parts.

Prevention of the entry of foreign objects must be taken into account during disassembly of the service
location.

Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.

Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.

Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
