I know where you're going with that thought. I considered it as well. It would be extremely difficult to do a failure analysis at this point, with no photographic or video evidence of the break. I also would like to see the fracture, measure the diameter and wall thickness of the driveshaft, and see if I could come up with a torque value that could have produced the failure.

I can guarantee that it was more than 15% of 230 lb/ft for sure.
