There was a story in Mopar Muscle awhile back where they wanted to build a low buck Dana 60. They got a truck axle as a core, and used some sort of Ford axle ends with large roller bearings. They were not tapered like our original Timkens, but they had far more contact area than a ball bearing does. I wonder why nobody else has thought of going with this setup. Maybe its because of the additional expense of modifying the housing?
