Check the tensioner and make sure it has the correct tension on the serpentine belt. Even with the proper tension, sometimes the belt will still squeal if it is older, after several years of use, especially if you live in a very hot climate, the belt can "glaze" and become slick. Hope it helps...JC
If the squeeling is coming from the tires, then the problem is most likely a misaligned front end. If the squealing is coming from the engine, then the problem would be in the power steering system.
Take it to a garage!
Check your coolant level.
