brought it in to have the tires balanced, they said two of my alloy's were bent and that's why it shook at high speeds. I have since replaced all 4 rims and bought new tires at the same time, had them balanced and had a 4 wheel alignment done and it still shook (although not as badly). I took it to a tire shop/garage, had them test drive it and they said it was a balancing issue so I had the tires re-balanced and it still shakes. I have no idea where to take it from here or what the issue may be now and it's driving me absolutely crazy that it still shakes!
