3. Temporarily tighten removed drive pinion lock nut to drive pinion.
NOTE:
Use removed drive pinion lock nut only for the preload measure-
ment.
4. Rotate drive pinion at least 20 times to check for smooth opera- tion of the bearing.
5. Tighten to drive pinion lock nut, while adjust pinion bearing pre- load torque.
CAUTION:

Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.

After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
6. If the pinion bearing preload torque is outside the specification, use a thicker/thinner drive pinion bearing adjusting washer and drive pinion adjusting washer to adjust.
Refer to FFD-40, "
Drive Pinion Bearing Adjusting Washer" and FFD-40, "Drive Pinion Adjusting Washer" .
7. Remove companion flange, after adjustment.
ASSEMBLY
Drive Pinion Assembly
1. Install pinion front and rear bearing outer races using drifts.
CAUTION:

At first, using a hammer, tap bearing outer race until it
becomes flat to gear carrier.

Do not reuse pinion front and rear bearing outer race. Tool number A: ST3127S000 (J-25765-A)
Drive pinion lock nut tightening torque: 127.4 - 245.0 N·m (13.0 - 25.0 kg-m, 94 - 181 ft-lb)
Pinion bearing preload: 0.78 - 1.57 N·m (0.08 - 0.16 kg-m, 7 - 13 in-lb)
When the preload torque is large: Decrease the drive pinion bearing adjusting washer and drive pinion adjusting
washer thickness.
When the preload is small: Increase the drive pinion bearing adjusting washer and drive pinion adjusting
washer thickness.
