3. Press inner race of side bearing (left) to center stem assembly,

using the drift (A) (Commercial service tool).

CAUTION:

• Never reuse side bearing.

• Apply gear oil to side bearing.

4. Install side bearing adjusting shims (2 pieces for right side) with

the same thickness as the ones installed prior to disassembly or

re-install the old ones, with outer race of side bearing to center

stem assembly.

If side bearing adjusting shims have been already selected, use

them.

CAUTION:

• Never reuse side bearing.

• Apply gear oil to side bearing.

5. Set the drifts (A and B) to the right and left side bearing adjusting

shims individually. Press center stem assembly with side bear-

ing to install gear carrier assembly to center stem assembly.

CAUTION:

• The drift shall be placed on the center of the adjusting

shims.

• The pressure shall be as low as possible to install differ-

ential assembly into gear carrier assembly. The maximum

pressure shall be 10 kN (1 ton, 1.0 Imp ton).

• If the adjusting shims are installed by tapping, the gear carrier may be damaged. Avoid tapping.

6. Install dummy cover set, check and adjust drive gear runout, tooth contact, backlash, and total preload

torque. Refer to

DLN-162, "Adjustment"

7. Remove dummy cover set.
8. Apply liquid gasket (1) to mating surface of rear cover.

• Use Genuine Silicone RTV or equivalent. Refer to

GI-22,

CAUTION:

• Remove old gasket adhering to the mounting surfaces.

Also remove any moisture, oil, or foreign material adher-

ing to the mounting surfaces.

• The width of sealant bend is approximately 3 mm (0.012

in). Apply sealant evenly.

9. Set the drifts (A and B) to the right and left side bearing adjusting

shims individually. Compress center stem assembly with side

bearing to install 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, 1.0

Imp ton).

• If rear cover is forced in by tapping, rear cover may be damaged by adjusting shims. Avoid tap-

ping.

10. Tighten rear cover mounting bolts to the specified torque.

CENTER STEM ASSEMBLY

11. Install side oil seal (right) until it becomes flush with the gear car-

rier end, using the drift (A) [SST: ST33400001 (J-26082)].

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.

12. Install side oil seal (left) until it becomes flush with the gear car-

rier end, using the drift (A) [SST: KV38100500 (

—

)].

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.

13. Set gasket to drain plug. Install it to gear carrier.

CAUTION:

Never reuse oil gasket.

14. Set gasket to filler plug. Install it to gear carrier.

CAUTION:

• Never reuse oil gasket.

• After oil is refilled, tighten filler plug to specified torque.

15. Install carrier brackets.
16. Install electric controlled coupling. Refer to

DLN-156, "Assembly"

17. Check total preload torque. Refer to

DLN-162, "Adjustment"

18. Install breather tube (1) and breathers (2) with the paint mark (A)

facing vehicle rear within the angle (B) shown as follows.

TOTAL PRELOAD TORQUE

1. Before inspection and adjustment, drain gear oil.
2. Remove electric controlled couplings. Refer to

DLN-155, "Disassembly"

3. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.

4. Rotate drive pinion at least 20 times to check for smooth opera-

tion of the bearing.

5. Measure the total preload, using the preload gauge (A) [SST:

ST3127S000 (J-25765-A)].

NOTE:

Total preload torque = Pinion bearing torque + Side bearing

torque

• If measured value is out of the specification, disassemble it to

check and adjust each part. Adjust the pinion bearing preload and side bearing preload.

Adjust the pinion bearing preload first, then adjust the side bearing preload.

DRIVE GEAR RUNOUT

1. Remove rear cover. Refer to

DLN-159, "Disassembly"

2. Following the procedure below, install the dummy cover set [SST: KV381096S0 (

—

)] to gear car-

rier.

a. Temporarily install the bearing guides [SST: KV38109610 (

—

), KV38109620 (

—

)] to

gear carrier.

b. Position the dummy cap spacers [SST: KV38109630 (

—

), KV38109640 (

—

)] and the

angle [SST: KV38109650 (

—

)] to bearing guide.

c. Use rear cover mounting bolts, tighten bolts to the specified torque. Refer to

DLN-158, "Exploded View"

d. Tighten dummy cap spacer mounting bolts evenly to the specified torque.

3. Fit a dial indicator to the drive gear back face.
4. Rotate the drive gear to measure runout.

• If the runout is outside of the repair limit, check drive gear

assembly condition; foreign material may be caught between

drive gear and center stem, or center stem or drive gear may

be deformed, etc.

CAUTION:

Replace drive gear and drive pinion as a set.

TOOTH CONTACT

1. Remove rear cover. Refer to

DLN-159, "Disassembly"

)] to gear car-

rier.

a. Temporarily install the bearing guides [SST: KV38109610 (

—

), KV38109620 (

—

)] to

gear carrier.

Total preload torque

: Refer to

DLN-175, "Pre-

load Torque"

When the preload torque is large

On pinion bearings:

Replace the collapsible spacer.

On side bearings:

Use thinner side bearing adjusting shims. For selecting adjusting
shim, refer to the latest parts information.

When the preload is small

On pinion bearings:

Tighten the drive pinion nut.

On side bearings:

Use thicker side bearing adjusting shims. For selecting adjusting
shim, refer to the latest parts information.
