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.

8.

Install coupling cover to final drive assembly with arrow facing
upward, temporarily tighten reamer bolts to the positions shown
in the figure.

9.

Tighten reamer bolts and coupling cover mounting bolts to the
specified torque.

10. Install electric controlled coupling breather hose to coupling

cover.

11. Install connector bracket, and tighten bolts to the specified

torque.

12. Connect 4WD solenoid harness connector.

13. Install companion flange.

NOTE:
When reusing electric controlled coupling, align the matching
mark of electric controlled coupling with the matching mark of
companion flange, then install companion flange.

14. Install companion flange lock nut with flange wrench (commer-

cial service tool), tighten to the specified torque.

CAUTION:

Never reuse companion flange lock nut.

15. Check companion flange runout. Refer to 

DLN-133, "Adjust-

ment"

.

16. Install rear propeller shaft. Refer to 

DLN-110, "Exploded View"

.

17. When oil leaks while removing, check oil level after the installation. Refer to 

DLN-120, "Inspection"

.
