I called one dealer today, they want to keep our Expedition for up to 3 days to fix this. Calling the other dealer (that I was trying to avoid) tomorrow to see what they say. In the meantime I'm more than likely going to just go over to Discount Tire and have them balance (or try) the tires and see if that makes it manageable. I would really like to have some kind of record with Ford, though, that I had the issue in case they offer something in the future for those of us that had issues.
