4) Tighten the new lock nuts using ST1, ST2 and
ST3.
Using the following equation, calculate the tighten-
ing torque.
T2 = L2/(L1 + L2) × T1
T1: 116 N·m (11.8 kgf-m, 85.3 ft-lb)
[Required torque setting]
T2: Tightening torque

4) Adjust the drive pinion and hypoid driven gear
backlash.
5) Apply red lead evenly to the surfaces of three or
four teeth on hypoid driven gear. Rotate the drive
pinion in the leftward and rightward for several

tooth contact pattern.
If the teeth contact is inappropriate, adjust the
backlash or thickness of the shim.
•Correct tooth contact
Check item: Tooth contact surface is slightly
shifted toward the toe side under a no-load con-
dition. (When driving, it moves towards the heel
side.)
