I don't know about the squeeling, but it is normal on thunderbirds for the top of the tire/wheel to be canted inward a little bit. I have had four Tbirds, and every one that I have seen is like that, and an alignment tech. made a comment about that to me just the other day. You may still need an alignment though. What kind of tires do you have on your car? If they are on the lower end of the quality ladder, that might be at least part of the problem.
