Differential Ring Gear Installation
1. Heat differential ring gear to about 100° C (212° F) in oil bath.
2. Clean mating surfaces of differential ring gear and differential case.
3. Install differential ring gear to differential case.
4. Install new 4 ring gear set bolt lock plates and 8 bolts and tighten bolts to specified torque.
Tightening Torque (a): 99 Nm (9.9 kg-m, 72.0 ft. lbs.)
5. Clamp bolts with lock plate securely.
6. Install differential assembly to transmission case and tighten case bolts to specified torque.
