If it wasn't doing it before the alignment, I would take it back and ***** a bit. At least get a refund. I keep hearing the dealer for $100 is the best for alignments

If it's the tires it will usually be one bad tire causing issues. "Tracking" is common on low profile and high performance tires . My BMW would wander or "track". A Different set of tires fixed it. I don't think it's the problem in your case.

You could always put the front on the rear, and visa versa, to test a little
