Steering Problem 1998 Econoline Conversion Van

To start with, I have had two minor front end collisions with this van. Both have involved the steering system.

My problem is that I cannot get the steering to be solid. That is, the van seems to wander with the smallest of variations in the pavements. I have had it to several shops including the local dealership and they all say the alignment is right and according to specs.

Can anyone advise me of a specialty shop in the Tidewater Virginia area that could diagnose and fix a steering problem like mine?

That sounds like it is most likely frame damage.  Hunt around for a really good front end shop and have they check it out.  They may need to check front and back.  Look for worn parts as well.
