and install drive pinion using a suitable press and suitable tool.
Stop when drive pinion touches the bearing.
6. Install the front oil seal using Tool. Refer to RFD-6, "
Removal and Installation" .
7. Install the companion flange, and tighten the pinion nut to a min-
imum using Tool. Check that the threaded portion of the drive

8. Tighten the drive pinion nut by very small increments until the
specified preload is achieved, when checking the preload, turn
drive pinion in both directions several times.

If the pinion bearing preload is less than specification, tighten
the drive pinion nut.
