I now have 1,350 miles and I still have a slight shake coming from my rear right side of the car. happens around 65mph - 75mph and I can see my passenger seat wobble back and forth and can feel it in my drivers seat and slightly under the car as if it hops around those speeds.
I am taking the car back in again to the dealership Monday morning, would anyone else know what the 'cause of this would be?
If the car was vibration free after the dealer replaced the front, driver's tire, you might have simply lost a weight off one the wheels, or perhaps you have hit a pothole and bent a wheel?
