Rockwell axle w/12 inch ring gear:

This axle, Fig. 13, employs a heavy duty hypoid drive pinion and ring gear. The differential and gear assembly is mounted on tapered roller bearings. The straddle mounted pinion has two tapered roller bearings in front of the pinion teeth which take the forward and reverse thrust, while a third bearing behind the pinion teeth carries the radial load.
