Unbelievable!!!!
Reading about the broken axle made me go out and inspect it to see if I could see if that was the problem, and I can't believe it! I didn't notice before that the passenger side axle wasn't moving when I rolled the car. I thought both axles were moving, but I just noticed that it doesn't move, so it looks like the axle stub must have sheared off in the hub!
Maybe my diff is OK and it's just the axle.
Alright - change of plans, I guess I'm going to have to pull this thing apart now instead of finishing the motor install on another car
