A few weeks ago, while taking THRAMP on a long trailer ride, one of the nuts on the upper A-arm worked itself loose (I hadn't tightened 'em yet) and got lost. No problem, I thought; didn't need 'em yet so I'll just get one later. Well, now I find it's nearly impossible to find a 7/16 fine-thread flanged nut at any hardware stores around here. Yesterday my wife was visiting the garage, and happened to idly turn the right front wheel. "This one doesn't turn very well," she says, and demonstrates. Wheel goes ch-ch-chunk and grabs. Immediately, I think "crap, I just replaced the bearings in the Mustang about 6 months ago, WTF???" 
Later, I investigated, with same results. I happened to look down, and I saw my nut! No, the other one. Somehow, it had gotten down into the inner edge of the brake disk; when I turned the wheel, it would bounce around off the cooling fins and sometimes catch on the lower ball joint knuckle.
Just thought I'd post because it was a very unusual set of circumstances, and a much easier fix than I first thought. Still can't figure out how it got there, though - that's an odd trajectory from the bolt it came off of, and we'd rolled the car off the trailer and into the garage and hadn't notice it.
The moral of the story? Check your nuts!
