Drive Pinions

CAUTION: Be sure to follow the correct procedure for setting the bearing preload when the nut is installed.

On some high-mileage units, oil may leak past the threads of the pinion nut. This condition can be corrected by removing the nut and applying Pipe Sealant with Teflon D8AZ- 19554-A or equivalent meeting Ford specification WSK-M2G350-A2 on the threads and nut face.
