I went to metallurgy sheets etc . the one thing I found was to get the gears already polished from the factory. less break in tighter tollerances, quieter. 5 cut has a taper where 2 cut has no taper from toe to heal. straight cut gears. that might have an influence on failure. pure speculation on my part. the oldman...........

Two cut gears are face hobbed. Good point about strength, though. Two cut gears are supposed to be weaker than 5 cut gears due to the reduced contact patch. Can you even buy 5 cut gears for these rears?
