1.

Remove side oil seals, using a suitable tool.

CAUTION:

Be careful not to damage gear carrier and rear cover.

2.

Remove rear cover mounting bolts.

3.

Set drifts [SST: KV40100610 (J-26089)] to the right and left side
bearing adjusting shims individually. Press differential case
assembly with side bearing to remove gear carrier assembly
and rear cover assembly.

CAUTION:

The pressure shall be as low as possible to remove gear
carrier assembly and rear cover assembly. The maximum
pressure shall be 10 kN (1 ton, 1.1 US ton, 1.0 Imp ton).
NOTE:
Differential case assembly, side bearings, and adjusting shims
are compressed and integrated in gear carrier and rear cover.

4.

Remove drain plug and filler plug.

5.

Remove side bearing adjusting shims and side bearing outer races.

CAUTION:

Mark the side bearing adjusting shims so that the original mounting positions (right/left) can be
identified later.

6.

Remove drive gear mounting bolts and then remove drive gear
from differential case.

7.

Remove side bearing inner races, using pullers and the drift
[SST: ST33052000 (

—

)].

case.

3.

Align 2 pinion mate gears in diagonally opposite positions, then
rotate and install them into differential case after installing pinion
mate thrust washers to pinion mate gears.
