Drive Pinion
Failure to de-stake the pinion nut will result in damage to
the drive pinion threads when removed. The pinion nut
should never be reused, always replace with new.
5. Remove the pinion nut.
6. Place carrier assembly into a press, place a 2" x 6" x
6" wood block under the pinion. This will ensure that
when the pinion is pressed free from the bearings
the pinion will not be damaged.
7. Use the proper pressing tool to press the end of the
pinion until free from the pinion bearings.
8.
Forward Axles Only: Remove the pinion spacer and
the helical gear.
The bearing spacer will be reused or used as a starting
point when resetting the pinion bearing preload. Do not dis-
card this part.
