My TBSS has a vibration from the driver's side. I think it is the front. It only happens from about 42 to 48 MPH. It is stronger when turning right and the left side is loaded. I can feel vibrations in the steering wheel and it kinda sounds like a big propeller-driven WW2 airplane. I replaced the hub with a quality part (Moog), but the problem remains. Could it be the tire? What else can I check before going to the dealership? Thanks.
