1.

Remove connector bracket.

2.

Put matching mark on the thread edge of electric controlled cou-
pling. The matching mark should be in line with the matching
mark on companion flange.

CAUTION:

For matching mark, use paint. Never damage electric con-
trolled coupling.
NOTE:
When replacing electric controlled coupling, matching mark is
not necessary.

3.

Remove companion flange lock nut, using a flange wrench
(commercial service tool).

4.

Remove companion flange.

5.

Remove coupling cover.

6.

Remove front oil seal from coupling cover, using flat-bladed
screwdriver.

CAUTION:

Be careful not to damage coupling cover.

7.

Remove electric controlled coupling.

8.

Remove 4WD solenoid harness.

9.

Remove coupling front bearing, using pullers and then take off
bearing shim from electric controlled coupling.

10. Remove center oil seal from gear carrier.

ELECTRIC CONTROLLED COUPLING

1.

Using the drift (A) (SST: ST35271000), install center oil seal (1)
as shown in the figure.

CAUTION:

• Never reuse oil seal.
• When installing, never incline oil seal.
• Apply multi-purpose grease onto oil seal lips, and gear oil

onto the circumference of oil seal.

2.

Install bearing shim and coupling front bearing to electric con-
trolled coupling, using the drift (SST: 22360002).

CAUTION:

• Never reuse bearing shim and coupling front bearing.
• When assembling bearing shim, shim chamfer side

should face electric controlled coupling side.

• Apply gear oil to coupling front bearing and bearing shim.

3.

Connect 4WD solenoid harness to electric controlled coupling.

4.

Install electric controlled coupling to spline of drive pinion inside
gear carrier.

CAUTION:

• Align the pin on electric controlled coupling with the

groove of gear carrier.

• Be careful not to damage center oil seal.

5.

Set 4WD solenoid harness guide to gear carrier.

6.

Using the drifts, drive front oil seal until it becomes flush with the
coupling cover end.

CAUTION:

• Never reuse oil seal.
• When installing, never incline oil seal.
• Apply multi-purpose grease onto oil seal lips, and gear oil

onto the circumference of oil seal.

7.

Apply liquid gasket to mating surface of coupling cover. Overlap
both ends of the bead for at least 3 mm (0.12 in).

CAUTION:

Remove old gasket adhering to the mounting surfaces.
Also remove any moisture, oil, or foreign material adhering
to the mounting surfaces.
