10. Tighten the pinion nut by very small degrees until the specified preload is achieved. When checking the preload, turn the drive pinion in both directions several times to set the bearing rollers.

Tool number : ST3127S000 (J25765-A) 

Pinion bearing preload: 

2.3 - 3.4 N.m (24 - 34 Kg-cm, 21 - 30 in-lb) 

This procedure will have to be repeated if:

• Maximum preload is achieved before the minimum pinion nut torque is reached.
• Minimum preload is not achieved before maximum pinion nut torque is reached.
