Axle problems

Has anyone had any problems with the moser axles?I started with a pair of cut and resplined c body axles but upon inspection one day I noticed that I had twisted the splines on them so I upgraded to the mosers I've had them for about 7 years now before pulling them out because of a noisey gear which had a couple broken teeth I then discovered the same problem with the moser axle on the driver side
I twisted the strange axles in the ford 9" that was in my 406 vega also. If u are hooking up ,and got some power, I think they`ll all twist.
