I need to know if I bad strut mount will cause the front end to vibrate? It starts at around 50 mph and by the time you hit 65 mph it is really bad! I have rotated the tires around and it made no difference. I do know it is the front passenger side for sure! Prior to tue vibration there was/is a roaring noise coming from the same side. I thought it might have been the wheel bearing but the is no slack/play in the wheel at all. I am hoping that you guys could help me figure this thing out.
