I cant believe someone cleaned up all the shavings put it back together and said should be fine. gave it back to the owner and said drive it..... it will be fine. WTF.

Then vibration and contact between drive shaft and pinion coupler. then the pinion nut comes loose. the pinion gets into the Carrier. Here we are.^
That must have really taken some work to get that far off
