Well, I'm back rolling in the truck: Total damage: $168.02 to Ford for finding it, and replacing my wheel studs -- parts and labor. 5 wheel studs is about $80 by the way -- not a trivial expense at the dealership!
Here's the wheel after my FUBAR:
I had a nice talk with the service manager Tim about what does and does not void warranty coverage. I'll post on that later. It's pretty interesting.
Now I have to spend $93.00 for a replacement wheel, which includes mounting my tire on it and balancing it. All-in-all: a costly mistake for me!
