It's hard to steer after replacing power.

There are some major recalls on the windstar (i have an 01 windstar). One of the recalls has to do with loss of steering. There is one having to do with the frame / subframe? Rusting out due to dripping from a/c. There is another for axles breaking due to rust and hairline fractures in the rear axle. My local dealer didn't even know how to do the inspections correctly. I'd search online for ford's recall info which includes their documentation. They are buying back some cars that meet certain criteria. Buy back amt according to their documentation is 1.5% book value but they'll give you a lowball offer. Just make a counteroffer and cite their documentation. You'll find that info in their documentation. Be safe.
