to the OP : my cuda is currently using its 4th set of green bearings in 3 years. Green bearings were installed along with a Wilwood rear disc brake kit. With the current configuration (no axle seals in the housing, and the inner bearing cage seal ripped out before installation, so the bearing can be lubricated by the diff fluid ), it seems the 4th set might outlive its three predecessors. Set #2 was really driven for one day (which included 20 spirited minutes on a racetrack).

I can't switch back to OE bearings easily (need custom length axles or a custom-length centre pivot in the Truetrac diff like I did in my Challenger), or else I would do it in a pinch.
