I have been having a weird vibration issues for the past few months. I can't tell if it has been getting worse. The vibration happens when traveling 50+mph (especially 60-70mph). The vibration is more noticeable when turning the steering wheel left (vibration becomes severe and whole car rattles). However, turning the wheel right makes the vibration go away completely (incredibly smooth like how the car should drive).
I don't have a reason to believe my alignment is off--tire wear seems to be OK. I've also visually inspected my suspension parts and cannot find anything broken or loose. The wheel bearings seem ok on the "wiggle the tire" test. There has never been any odd sounds (like metal clanking or grinding), only the vibration. I have rotated (back to front) and cross-rotated (left to right) my wheels yet there is no change in the vibration and direction.
