REAR FINAL DRIVE ASSEMBLY

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.
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 carrier case 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.
CAUTION:
Do not reuse the companion flange nut.
9. Check companion flange runout. Refer to RFD-19, "

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.

FRONT WHEEL HUB AND KNUCKLEPFP:40202
On-Vehicle InspectionEDS0005R
Inspect to check that there is no excessive play, cracking, wear, or
other damage to front axle.

Turn front wheels (left/right) and check the play.

Check that no nails or other foreign objects are embedded.

Retighten all axle nuts and bolts to the specified torque.
FRONT WHEEL BEARINGS
With the vehicle raised, inspect the following.

Move wheel hub in the axial direction by hand. Check that there is no looseness of front wheel bearings.

Rotate wheel hub and check that there is no unusual noise or other irregular conditions. If there are any
irregular conditions, replace the wheel bearing.
Removal and InstallationEDS0005S
REMOVAL
1. Remove tyre. Remove brake hose lock plate from strut.
