It just never ends does it?

Did you check the tail shaft on trans after twisting drive shaft?

Yes I did, thoroughly inspected everything even though it wasn't a violent event.
It twisted off right at the front yoke at a green light, and was so not out of balance I thought it was the rear end at first.
The car was barely moving and what was left of the shaft was laying on top of the exhaust pipes hardly turning until the car was fully stopped.
Basically just the yoke and Ujoint with a little bit of the tube metal was spinning on the back of the trans.

This feels so like a tire shudder.
