but look at ford 9" and GM 12/14 bolt rears. they all use a flat roller bearing, IIRC, which doesn't carry thrust loads any better than a ball bearing....






This is an apples and oranges comparision because a FLAT ROLLER carries ZERO LOAD , the thrust load is carried by the end of the axle by a C clip and we all know what happens when the C clip lets go.






umm, err, how many ford 9" rear are C-clip axles?
