Update: Car is still very unsteady/not planted/twitchy on the highway, feels like there is constantly a cross wind.

My local indy has no advice. The local dealer said they thought it was the steering rack but couldnt say for sure. We replaced the steering rack, and did alignment #5 , not the problem.

So far I have replaced all front control arms, sway bar, sway bar links, tie rods, tie rod ends, entire steering rack, all rear control arms except the large lower arms. I have also installed another entire set of wheels and tires.

I've had the car on jacks more time than I can count and still cannot find anything loose.

Im about at the end of my rope with it.
