06 sedan AT, 128k. Bad vibration from steering wheel at 70+ mph. Car tracks super straight. I really doubt it's a tire wheel issue because I had them rotated and balanced and nothing changed. Besides paying for an alignment to try to find slack in a steering component what is a typical culprit on these cars? It's driving me nuts. Thanks

 

check to see if your brake pads dragging. and check all of your bushings to see if they are not worn and intact.

 

How do you check to see if brake pad is dragging?
