Drive Pinion Nut

CAUTION:

Be sure to follow the correct procedure for setting the bearing preload when the nut is installed. See COMPANION FLANGE REAR REMOVAL / INSTALLATION or for the rear axle or See COMPANION FLANGE REMOVAL / INSTALLATION for the front axle.

On some high-mileage units, oil may leak past the ft threads of the pinion nut. This condition can be corrected by removing the nut and applying sealant on the threads and nut face.
