I generally don't replace bearings unless they are discolored (from heat) or spalded (marked). I wash them up in gasoline and dry them, repack them and install.
I was thinking about that the other day, was it ball bearing they use to say use fibered wheel bearing grease in?? I don't think you can even buy fibered wheel bearing grease anymore? The new blends of grease are probably better anymore anyway.
