Alright, so this noise has been getting louder slowly over the past few weeks. It is a high pitched noise that varies with wheel speed only, seemingly peaking around 50mph and only increasing slightly from that point onward. It seems to be coming from the rear passenger side area.
Now everyone I have talked to says it is not a wheel bearing, and my wheel was checked for play and for the traditional bearing noises. So I am confused as to what it might be.
The noise does not change when I put the car in and out of gear while coasting, although it does deepen in pitch slightly when I apply the brakes. It also occurs on dirt roads and loose packed surfaces.
Does anybody have any ideas about this? I am somewhat at a loss, but I will be putting the car on a lift soon in order to listen to it being driven in place.
