Tonight while I was driving home in my gen3 on the highway I began to hear this noise in the rear of my car. When I got off the highway I checked what was making the sound but I was unable to find out what was causing the noise. The noise is audible when the car is moving and goes with the rotation of the wheels. The noise is more audible in the cabin of the car. The noise is more audible when the car is moving slowly. The sound comes from the backseat of the car. Im thinking that it has something to do with the rear strut and the tires rubbing it? Can someone help?
