4. If the tooth contact is improperly adjusted, adjust the drive 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
washer to move drive pinion closer to the drive gear
For selecting adjusting washer, refer to the latest parts infor-
mation.

DIFFERENTIAL ASSEMBLY
 If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), use a thinner drive pinion height adjusting
washer to move the drive pinion farther from the drive gear.
For selecting adjusting washer, refer to the latest parts infor-
mation.
BACKLASH
1. Remove carrier cover. Refer to DLN-168, "Disassembly".
2. Fit a dial indicator to the drive gear face to measure the back- lash.
 If the backlash is outside of the specification, change the thick-
ness of the side bearing adjusting washers.
CAUTION:
Never change the total amount of wash ers as it changes the preload torque.
InspectionINFOID:0000000006222395
INSPECTION AFTER DISASSEMBLY
Drive Gear and Drive Pinion
 Clean up the disassembled parts.
 If the gear teeth never mesh or line-up correctly, det ermine the cause and adjust or replace as necessary.
 If the gears are worn, cracked, damaged, pitted or ch ipped (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).
Side Gear and Pinion Mate Gear
 Clean up the disassembled parts.
 If any cracks or damage on the surfac e of the tooth is found, replace.
 If any worn or chipped mark on the contact si des 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.

Backlash : Refer to DLN-185, "Back-
lash".
When the backlash is large: Make drive gear back side adjusting washer thicker,
and drive tooth side adjust ing washer thinner by the
same amount. For selecting adjusting washer, refer to
the latest parts information.
If the backlash is less than specification: Make drive gear back side ad justing washer thinner,
and drive tooth side adjust ing washer thicker by the
same amount. For selecting adjusting washer, refer to
the latest parts information.
