Until recently, the car ran quiet at highway speeds of 60mph and higher. Now I am noticing a sound that seems to be in the front. It's hard to describe but it sounds like a rotational sound. It's not a loud sound but one that you notice if the radio is off. I thought it was the tire, but they're fairly new with no signs of wear.
Perhaps it is a suspension part. Can you point me as to which part? Thanks
