"However, I do know you can screw up one pretty quick by over tightening the axle nut. Seen it quite a few times with morons and their impacts."

I've heard this.. yet I watch dealership guys zip them on with impacts, watch my buddy who has his own shop zip them on and I learned to zip them on with impacts. Oddly enough the failure rate isn't any better/worse than torquing properly. I know what you are saying and agree, proper torque should be followed. Meanwhile...I'm going to keep zipping them on unless someone requests otherwise.
