ADJUSTMENT
1. DIFFERENTIAL BEVEL PINION GEAR BACKLASH
1. Disassemble the front differential assembly. Front Differential Assembly > DISASSEMBLY">
2. Select the adjusting washer from the table and install.

Part No. | Thickness mm (in) |
803038021 | 0.925 — 0.950 (0.0364 — 0.0374) |
803038022 | 0.975 — 1.000 (0.0384 — 0.0394) |
803038023 | 1.025 — 1.050 (0.0404 — 0.0413) |
3. Adjust until the standard value is obtained.
Backlash:
Standard
0.13 — 0.18 mm (0.0051 — 0.0071 in)
2. HYPOID DRIVEN GEAR BACKLASH
Adjust the backlash by rotating the differential side retainer in the RH side case.
| ST 18630AA010 | WRENCH COMPL RETAINER |

NOTE:
Each time the side retainer rotates by one notch (A), the backlash changes by 0.05 mm (0.020 in).

3. TOOTH CONTACT OF HYPOID DRIVEN GEAR
1. Adjust until correct teeth contact is obtained.
2. Check tooth contact, and perform the adjustment as follows.
• Correct tooth contact
Check item: Tooth contact surface is slightly shifted toward the toe side under a no-load condition. (When driving, it moves towards the heel side.)

(A) | Toe side |
(B) | Heel side |
• Face contact
Check item: Backlash is too large.
Contact pattern

Corrective action: Tighten the differential side retainer to move the driven gear closer to the drive pinion shaft.

• Flank contact
Check item: Backlash is too small.
Contact pattern

Corrective action: Loosen the differential side retainer to move the driven gear away from the drive pinion shaft.

• Toe contact (inside contact)
Check item: Teeth contact area is too small.
Contact pattern

Corrective action: Increase the thickness of drive pinion shim and tighten the differential side retainer to move the driven gear closer to the drive pinion shaft according to the procedure for bringing drive pinion shaft away from driven gear.

• Heel contact (outside end contact)
Check item: Teeth contact area is too small.
Contact pattern

Corrective action: Reduce thickness of the drive pinion shim according to the procedures for moving the drive pinion shaft closer to driven gear. Also loosen the differential side retainer to move the driven gear away from the drive pinion shaft.
