NOTE: Hammering on the pinion flange will close in the bearing bores and misalign the flange lugs. This will result in premature failure of the journal needle bearings. Serious damage will also occur internally to the differential ring gear and pinion or pinion bearings by hammering on external parts. Remove and install the pinion flange using only the procedures in this service information.

Using the Yoke Remover, remove the pinion flange.
