If you have a warped brake disk, can it cause the steering wheel to shake, even if you're not pressing on the brake pedal? I have a vibration that becomes noticeable at about 60mph and up. I've rotated my tires. Balanced my tires. Got some new tires. And, I know I have at least one warped disk, and will be doing my brakes soon. I'm just not sure if that's what could be causing my wheel to shake. Any thoughts?
