5.

Assemble collapsible spacer to drive pinion.

CAUTION:

• Be careful of the mounting direction of collapsible spacer.
• Never reuse collapsible spacer.

6.

Apply gear oil to pinion front bearing, and assemble pinion front
bearing inner race to drive pinion. Using the drifts and stand,
press pinion front bearing inner race to drive pinion as far as
drive pinion nut can be tightened.

CAUTION:

Never reuse pinion front bearing inner race.

7.

Apply anti-corrosive oil to the thread and seat of drive pinion nut,
and temporarily tighten drive pinion nut to drive pinion.

CAUTION:

Never reuse drive pinion nut.

8.

Fit the drive pinion socket (A) (SST: KV38108500) onto the drive
pinion spline. Using the pinion nut wrench (B) (SST:
KV38108400), adjust the drive pinion nut tightening torque and
pinion bearing preload torque.

CAUTION:

• Adjust the lower limit of the drive pinion nut tightening

torque first.

• If the preload torque exceeds the specified value, replace

collapsible spacer and tighten it again to adjust. Never
loosen drive pinion nut to adjust the preload torque.

• After adjustment, rotate drive pinion back and forth 2 to 3

times to check for unusual noise, rotation malfunction,
and other malfunctions.

9.

Install differential case assembly. Refer to 

DLN-137, "Assem-

bly"

.

CAUTION:

Never install rear cover.

10. Install dummy cover set, and check drive gear runout, tooth contact, and backlash. Refer to 

DLN-146,

"Adjustment"

.

11. Remove dummy cover set, then install rear cover, and side oil seal. Refer to 

DLN-137, "Assembly"

.

12. Check total preload torque. Refer to 

DLN-146, "Adjustment"

.

13. Install electric controlled coupling assembly. Refer to 

DLN-131, "Assembly"

.

14. Check companion flange runout. Refer to 

DLN-133, "Adjustment"

.

TOTAL PRELOAD TORQUE

1.

Remove electric controlled coupling assembly. Refer to 

DLN-131, "Disassembly"

.

2.

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

3.

Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.

4.

Fit drive pinion socket onto drive pinion spline. Measure the total
preload, using the preload gauge (A) (SST: 3127S000) and drive
pinion socket (B) (SST: KV38108500).

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-135, "Disassembly"

.

2.

Following the procedure below, install a dummy cover set (SST: KV389L0010) to gear carrier.

a.

Set dummy cover shims to the right and left side bearing adjusting shims.

b.

Temporarily tighten dummy cover to gear carrier.

c.

Position dummy cover spacers to dummy cover.

d.

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

DLN-141, "Exploded View"

.

e.

Tighten dummy cover 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 differential case, or differential case or drive
gear may be deformed, etc.

CAUTION:

Replace drive gear and drive pinion as a set.

Standard

Total preload torque

: Refer to 

DLN-151, "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.

When the preload is small

On pinion bearings:

Tighten the drive pinion nut.

On side bearings:

Use thicker side bearing adjusting shims.

3.

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.

4.

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.

Tooth Contact Judgment Guide

5.

If 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), thicken drive pinion gear adjusting shim to
move drive pinion closer to drive gear.
