3. TOOTH CONTACT OF HYPOID GEAR
1. Adjust until correct teeth contact is obtained.
2. Check tooth contact, and perform the adjustment as follows.
• 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.)
