Disassembly

INFOID:0000000009718191

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 a suitable tool.

CAUTION:

Never damage coupling cover.

7.

Remove electric controlled coupling.

8.

Remove wave spring.

9.

Remove center oil seal from gear carrier.

CAUTION:

When removing electric controlled coupling, replace center
oil seal.

10. Remove AWD solenoid harness.

Assembly

INFOID:0000000009718192

1.

Using the drift (A) [SST: ST35271000 (J-26091)], 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.

• The specifications of center oil seals depend on the vehi-

cle-mounted electric controlled coupling. Therefore, when
replacing only a center oil seal, measure the inner diame-

: Apply Genuine High Strength Thread Locking Sealant or equivalent. Refer to 

GI-22, "Recommended Chemical Products 

and Sealants"

.

Refer to 

GI-4, "Components"

 for symbols not described above.

ter of the removed center oil seal to install a new one appropriate to the electric controlled cou-
pling. For selecting oil seal, refer to the latest parts information.

2.

Install wave spring to gear carrier.

3.

Connect AWD 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 AWD 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).
Use Genuine Silicone RTV or equivalent. Refer to 

GI-22, "Rec-

ommended Chemical Products and Sealants"

.

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 gear carrier 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 connector bracket, and tighten bolts to the specified

torque.

11. 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.

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

cial service tool), tighten to the specified torque.

CAUTION:

Never reuse companion flange lock nut.

13. Check companion flange runout. Refer to 

DLN-110, "Adjust-

ment"

.

Adjustment

INFOID:0000000009718193

COMPANION FLANGE RUNOUT

1.

Fit a dial indicator onto the companion flange face (inner side of
the rear propeller shaft mounting bolt holes).

2.

Rotate companion flange to check for runout.

3.

Fit a test indicator to the inner side of companion flange (socket
diameter).

4.

Rotate companion flange to check for runout.

5.

If the runout value is outside the runout limit, follow the procedure below to adjust.

a.

Check for runout while changing the phase between companion flange and drive pinion by 90

°

 step, and

search for the position where the runout is the minimum.

b.

If the runout value is still outside of the limit after the phase has been changed, replace companion flange.

c.

If the runout value is still outside of the limit after companion flange has been replaced, possible cause will
be an assembly malfunction of drive pinion and electric controlled coupling, malfunctioning coupling bear-
ing, or malfunctioning of electric controlled coupling.

Inspection After Disassembly

INFOID:0000000009718194

DRIVE GEAR AND DRIVE PINION

• Clean up the disassembled parts.
• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive

gear and drive pinion as a set.

BEARING

• Clean up the disassembled parts.
• If any chipped (by friction), pitted, worn, rusted or scratched marks, or unusual noise from the bearing is

observed, replace as a bearing assembly (as a new set).

SIDE GEAR AND PINION MATE GEAR

• Clean up the disassembled parts.
• If any cracks or damage on the surface of the tooth is found, replace.
• If any worn or chipped mark on the contact sides of the thrust washer is found, replace.

SIDE GEAR THRUST WASHER AND PINION MATE THRUST WASHER

• Clean up the disassembled parts.
