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

toe (toe contact), thin drive pinion gear adjusting shim to move
drive pinion farther from drive gear.
For selecting adjusting shim, refer to the latest parts informa-
tion.

BACKLASH

1.

Remove rear cover. Refer to 

DLN-247, "Disassembly and Assembly"

.

2.

Following the procedure below, install the 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-246, "Exploded View"

.

e.

Tighten dummy cover spacer mounting bolts evenly to the specified torque.

3.

Fit a dial indicator (A) to the drive gear face to measure the
backlash.

• If the backlash is outside of the specified value, change the

thickness of side bearing adjusting shims.

INSPECTION AFTER DISASSEMBLY

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).

Standard

Backlash

: Refer to 

DLN-263, "Backlash"

.

When the backlash is large:

Make drive gear back adjusting shims thicker, and drive 
gear front adjusting shims thinner. For selecting ad-
justing shim, refer to the latest parts information.

When the backlash is small:

Make drive gear back adjusting shims thinner, and 
drive gear front adjusting shims thicker. For selecting 
adjusting shim, refer to the latest parts information.

DIFFERENTIAL ASSEMBLY

Oil Seal

• Whenever disassembled, replace.
• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.

Differential Assembly

DIFFERENTIAL CASE

• Clean up the disassembled parts.
• If any wear or crack on the contact sides of the differential case is found, replace.

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.
• If it is chipped (by friction), damaged, or unusually worn, replace.
