Odd Comment in Mopar Action..

While it's true that a tapered roller bearing will handle more side loads than a ball bearing. The ball bearing bearings used in Green bearings or the fronts of most FWD cars are not like what you typically see as a ball bearing. They have two rows of balls with the inner race being split and pressed in from each side. these inner races wrap up onto the side of the balls providing a huge increase in the side load carring capacity over the more conventional ball bearing.

These ball bearing elements also for all practical puposes do not fail with out giving you plenty of warning. I have taken apart FWD hubs that the bearings were singing like a SOB only to find that you can't even feel any ruffness in them and the balls and races show no signs of overheating or burnnelling.

IMHO, if you have Green Bearings in your axle don't worry about them, they will let you know they are going a long time before they actually fail.

As for axles with roller bearings and the axles acting as the inner race, mopar 8.25 and I believe 9.25 are that way. FWIW, C-clips almost never fail either, the axle breaks outboard of the clip.
