Installed Z/G combo, got full alignment. Newer tires. Honestly, didn't drive the car enough before suspension install to know if it's been there before.

On some highways, anything over 50-60MPH feels like the car is on a train track doing it's own thing. It feels like it pulls left and then right and then left and there is no control over it. On other highways, the car does 100MPH and feels rock solid.

I've always known 'veering' cars to have worn out tie rods, but this one seems tied to a specific kind of road. Not sure if it's the grooves on certain highways, the tires, the alignment. Compression rods do this?

I can take some video that might explain it better, but wondering if there is anything I can check to fix this.

 

Did you let the springs settle before your alignment? and how bad was your camber after alighnment?

 

Springs settled for 2 days before alignment. Camber and toe were within OE spec. I can't remember the numbers but can call the shop on Monday and get exact numbers. Car drives straight and true otherwise.

 

Mine does the same. It started after I had new tires installed and only on one freeway that has noticeable grooves on it. What tires did you get? I have kumho Ecsta 4x. Other than on this 1 freeway, that I drive for only 5 miles, these are the best tires I've had on this car.

 

Outer tie and compressions rods are what I would check first. And by checking -that usually means just replacing if you feel any slop in the ball joint end on each rod.
