(1) Torque for 16 bolts ... 95 ± 10 N·m (70 ± 7 lb ft)
Note: After the bolts are torqued to the specification, tighten the bolts by an additional 1/2 turn.
(2) Backlash between the bevel gear and the pinion shaft ... 0.25 + 0.10 - 0.08 mm (0.010 + 0.004 - 0.003 inch)
(3) Tighten the nut until the torque wrench reading corresponds with the value in the following table:
