Something is broken in your suspension, whitton. Don't automatically rule out the rear, either. I know a guy who had a broken rear shock mount that caused the car to weave around on the highway. Have the dealer sift through the WHOLE suspension looking for anything loose or broken.

i saw a little play in ball join on a lift it play up a little like 1/16 it maybe
the trouble the isolinear dampers in the lower control arms Lincoln now offers an upgraded chronometric phased control arm which usually solves the problem.

Could be the tie rod ends or inner tie rod bushings.
