I just rotated and balance, plus, got 2 new tires, in the back. The tires in the front are fine, and the guys at discount tire did not notify me of any abnormality. Nonetheless, when I drive, I feel the wheel moving to the sides between 35 and 40 mph. At first I thought that it could be the imperfections of the road, but is only at that speed, if I go slower, nothing..
Any thoughts??

 

Check steering End-Links.
