b. Coat the threads of a new nut with hypoid gear oil.

c. Install the nut by tightening it until the standard preload is reached.

Torque: 451 N*m (4599 kgf*cm, 332 ft.*lbf) or less

d. Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.

Standard preload (at starting)

Specified Condition

New

3.11 to 3.61 N*m (32 to 36 kgf*cm, 28 to 31 in.*lbf)

Reused 2.14 to 2.45 N*m (22 to 24 kgf*cm, 19 to 21 in.*lbf)

If the preload is greater than the specification, replace the bearing spacer.

If the preload is less than the specification, retighten the nut with 13 N*m (130 kgf*cm, 9 ft.*lbf) of
torque at a time until the specified preload is reached.

Torque: 451 N*m (4599 kgf*cm, 332 ft.*lbf) or less

If the maximum torque is exceeded while retightening the nut, replace the bearing spacer and repeat
the preload procedure.

HINT:

Do not loosen the nut to reduce the preload.

38. INSPECT TOTAL PRELOAD

a. With the drive pinion contacting the tooth side of the ring gear, use a torque wrench to measure the

total preload.
