DIFFERENTIAL ASSEMBLY

17. Using the drift [SST: KV38100200 (J-26233)], drive side oil seals

until it becomes flush with the case 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.

18. Check and adjust drive gear runout, tooth contact, drive gear to

drive pinion backlash, and total preload torque. Refer to 

DLN-

170, "2WD : Adjustment"

.

Recheck above items. Readjust the above description, if neces-
sary.

19. Apply sealant (A) to mating surface of rear cover.

• Use Genuine Silicone RTV or equivalent. Refer to 

GI-15,

"Recommended Chemical Products and Sealants"

.

CAUTION:

Remove old sealant adhering to mounting surfaces. Also
remove any moisture, oil, or foreign material adhering to
application and mounting surfaces.

20. Install rear cover on gear carrier and tighten mounting bolts.

21. Install side flange with the following procedure.
a.

Attach the protector [SST: KV38107900 (J-39352)] to side oil
seal.

b.

After the side flange is inserted and the serrated part of side
gear has engaged the serrated part of flange, remove the pro-
tector.

c.

Put a suitable drift on the center of side flange, then drive it until sound changes.
NOTE:
When installation is completed, driving sound of the side flange turns into a sound that seems to affect the
whole final drive.

d.

Confirm that the dimension of the side flange (1) installation
measurement (A) in the figure comes into the following.

2WD : Adjustment

INFOID:0000000003135834

TOTAL PRELOAD TORQUE

Before inspection and adjustment, drain gear oil.

1.

Secure final drive assembly onto an attachment [SST: KV38100800 (J-25604-01)].

2.

Remove side flanges.

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 total preload with the preload gauge (A) [SST:
ST3127S000 (J-25765-A)].

NOTE:
Total preload torque = Pinion bearing preload torque + Side
bearing preload 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.

SIDE BEARING PRELOAD

Before inspection and adjustment, drain gear oil.
1.

Remove rear cover. Refer to 

DLN-164, "2WD : Disassembly"

.

2.

Make sure all parts are clean. Also, make sure the bearings are
well lubricated with gear oil.

3.

Place the differential case, with side bearings and bearing races
installed, into gear carrier.

4.

Insert left and right original side bearing adjusting washers in
place between side bearings and gear carrier.

Standard

Total preload torque

: Refer to 

DLN-207, "Pre-

load Torque"

.

JSDIA0031ZZ

When the preload torque is large

On pinion bearings:

Replace the collapsible spacer.

On side bearings:

Use thinner side bearing adjusting washers by the same amount to 
each side.

When the preload is small

On pinion bearings:

Tighten the drive pinion lock nut.

On side bearings:

Use thicker side bearing adjusting washers by the same amount to 
each side.

5.

Install bearing caps in their correct locations and tighten bearing
cap mounting bolts.

6.

Turn the carrier several times to seat the bearings.

7.

Measure the turning torque of the carrier at the drive gear
mounting bolts with a spring gauge [SST: 

—

 (J-8129)].

8.

If the turning torque is outside the specification, use a thicker/
thinner side bearing adjusting washer to adjust.

CAUTION:

Select a side bearing adjusting washer for right and left
individually.

9.

Record the total amount of washer thickness required for the correct carrier side bearing preload.

DRIVE GEAR RUNOUT

1.

Remove rear cover. Refer to 

DLN-164, "2WD : Disassembly"

.

2.

Fit a dial indicator to the drive gear back face.

3.

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 differential case, or differential case or drive
gear may be deformed, etc.

CAUTION:

Replace drive gear and drive pinion gear as a set.

TOOTH CONTACT

Before inspection and adjustment, drain gear oil.
1.

Remove rear cover. Refer to 

DLN-164, "2WD : Disassembly"

.

If the turning torque is less 
than the specified range:

Use a thicker thrust wash-
er.

Apply red lead to drive gear.

CAUTION:

Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on drive gear.

Rotate drive gear back and forth several times, check drive pin-
ion gear to drive gear tooth contact.

CAUTION:

Check tooth contact on drive side and reverse side.
