Whenever I hit about 90 MPH on the highway, I get a steady buzz. As you increase speed, the buzz gets louder and worse. I don't know if it's the rear end or what, but it fills the entire cabin with the noise. One time back in the 80's, my brother's Chevette rear end went out, it sounds like that. A low frequency buzz, but at low speeds you don't hear or feel anything. Any clue on what it could be?
