From Mopar Action:
Found by a yahoo search of 'Mopar green axle bearings'.
right or wrong

"Ray, the Greens are low-capacity ball bearings...maybe 1/10 the side-load capacity of the stock Timkens. They are fine for drag racing, pretty lousy on the street, and pretty scary if you're into cornering or towing! (Admittedly, I've never personally seen one catastrophically fail, but I've seen plenty get noisy and sloppy).

The Fords are sealed rollers, way better than balls. The reason why you don't see more of 'em is 'cause they require you to weld on custom axle housing "ends". I have featured these earlier in the mag, as a way to dump the C-clips on 8.25 and 9.25" axles.

I also must add that, except that they require more care during assembly (packing with lube, endplay adjustment, etc.) the stock Timken tapered roller setup is about as good as it gets.

OBVIOUSLY many people disagree
