ASSEMBLY INSPECTION AND ADJUSTMENT

• Drain the differential gear oil before inspection and adjustment. Refer to 

DLN-404, "Changing Differential

Gear Oil"

.

• Remove and install the carrier cover as necessary for inspection and adjustment. Refer to 

DLN-409,

"Removal and Installation"

.

Total Preload Torque

1.

Remove the side flanges if necessary. Refer to 

DLN-407, "Removal and Installation"

.

CAUTION:

The side flanges shaft must removed in order to measure total preload torque. 

2.

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

3.

Rotate the drive pinion at least 20 times to check for smooth operation of the bearings.

4.

Measure total preload torque using Tool.

NOTE:
Total preload torque = Drive pinion bearing preload torque +
Side bearing preload torque

• If the measured value is out of the specification, check and adjust each part. Adjust the drive pinion

bearing preload torque first, then adjust the side bearing preload torque.

CAUTION:

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

Drive Gear Runout

1.

Fit a dial indicator to the drive gear back face.

2.

Rotate the drive gear to measure runout.

• If the runout is outside of the limit, check the condition of the drive

gear assembly. Foreign material may be caught between the drive
gear and differential case, or the differential case or drive gear may
be deformed.

CAUTION:

Replace drive gear and drive pinion as a set.

Tooth Contact

Tool number

: ST3127S000 (J-25765-A)

Total preload torque:

2.84 - 3.75 N·m (0.29 - 0.38 kg-m, 26 - 33 in-lb)

SPD884

If the total preload torque is greater than specification

On drive pinion bearings:

Replace the collapsible spacer.

On side bearings:

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

DLN-432, "Inspection and Adjust-

ment"

.

If the total preload torque is less than specification

On drive pinion bearings:

Tighten the drive pinion lock nut.

On side bearings:

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

DLN-432, "Inspection and Ad-

justment"

.

Runout limit

: 0.05 mm (0.0020 in) or less

1.

Apply red lead to the drive gear.
NOTE:
Apply red lead to both faces of three to four gears, at four loca-
tions evenly spaced on the drive gear.

2.

Rotate the drive gear back and forth several times. Then check
for correct drive pinion to drive gear tooth contact as shown.

CAUTION:

Check tooth contact on drive side and reverse side.

3.

If the tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).

• If the tooth contact is near the face (face contact), or near the heel

(heel contact), use a thicker drive pinion height adjusting washers
to move the drive pinion closer to the drive gear.
Refer to 

DLN-432, "Inspection and Adjustment"

.

• If the tooth contact is near the flank (flank contact), or near the toe

(toe contact), use a thinner drive pinion height adjusting washers to
move the drive pinion farther from the drive gear.
Refer to 

DLN-432, "Inspection and Adjustment"

.
