(4) Position the special tool in the side bearing seat of the
gear carrier, and then select a drive pinion rear shim
of a thickness which corresponds to the gap between
the special tools.
NOTE
Clean the side bearing seat thoroughly.
When selecting the drive pinion rear shims, keep the
number of shims to a minimum.
(5) Fit the selected drive pinion rear shim(s) to the drive
pinion, and press-fit the drive pinion rear bearing inner
race by using the special tool.
Adjust the drive pinion rotation torque by using the following
procedures:
(1) Fit the drive pinion front shim(s) between the drive pinion
spacer and the drive pinion front bearing inner race.
(2) Tighten the companion flange to the specified torque by
using the special tools.
NOTE
Do not install the oil seal.
(3) Measure the drive pinion rotation torque (without the oil
seal) by using the special tools.

When selecting the drive pinion front shims, if the number
of shims is large, reduce the number of shims to a minimum
by selecting the drive pinion spacers.
