5. Using the pin punch below, drive a lock pin into the pinion mat-
ing shaft.
CAUTION:
Do not reuse the lock pin.
6. Using the drift below, press a side bearing inner race into the dif-
ferential case.
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.
10. Fit the drift below to the right and left side bearing adjusting shims individually. Compress differential case
assembly and side bearing to install the gear carrier 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
gear carrier assembly into the differential assembly. The
maximum pressure shall be 1 ton.
If the adjusting shims are installed by tapping, the gear
carrier may be damaged. Avoid tapping.
11. Install a dummy cover set, check and adjust the backlash, drive
gear back runout, tooth contact, and overall preload torque.
Refer to RFD-17, "
Pre-inspection" .
12. Remove dummy cover set.Tool number : ST23550000

REAR FINAL DRIVE ASSEMBLY
13. Apply a continuos bead of sealant around the gear carrier 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 drift below to the right and left side bearing adjusting
shims individually. Compress differential case assembly and
side bearing to install the rear cover.
CAUTION:
The 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 10 kN (1 ton,
1.1 US 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. Refer to RFD-16, "
Components" .
16. Using both drift, drive the oil seal until it becomes flush with the
case end.
CAUTION:
Do not reuse oil seals.
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-17, "
TOTAL PRE-
LOAD" .
Installation of Electric Controlled Coupling Assembly
1. Using the drift below, install the coupling front bearing to the
electric controlled coupling.
CAUTION:
At disassembly, be sure to install shim between electric
controlled coupling and bearing. Chamfering side of shim
should be coupled to install.
2. Assemble the electric controlled coupling assembly to the drive pinion gear.

CAUTION:
Remove old sealant on the mounting surface, then remove
any moisture, oil, and foreign material from the application
and mounting surfaces.
5. Assemble the coupling cover to the gear carrier assembly with
the arrow facing upward, temporarily tighten reamer bolts to the
positions shown in the figure.
6. Tighten the reamer bolts and coupling cover mounting bolts to
the specified torque.
7. Assemble the companion flange.
8. Using a flange wrench, tighten the companion flange nut to the
specified torque.

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.
