This was my thought also. Seems like every time I've heard of a Dana having problems keeping a gear in it, you end up finding the housing was bent.
Monte Smith warned me about this years ago when I decided to keep my Dana and not change to a 9".

I think this could be happening on the launch. I know Doug is pretty methodical so, a small change in set-up may not change the service life. But I hope it does! A long time ago, I was told about every rear can use help with fore-aft reinforcement. So, i just do it. This is one i made for Randy's Dana with .375 wall axle tubes.
