My car has been sitting for about 2 months while I was recovering from an incident where I tried to remove a couple of fingers from my right hand with the winch on my Jeep. Anyways, when I drove it for the first time I was really shocked at how loud the car seemed. At first I thought it was just wind noise and i wasn't used to it because i had been driving my truck all the time. The thing is the noise, which sounds sort of like wind noise or maybe friction from two pieces of metal just slightly rubbing together, starts almost as soon as the car is moving. it is definitely coming from the rear of the car. Is this just normal drive line noise that I had forgotten about since i haven't been driving the car or could it be something else? i thought maybe I had a rear brake not totally disengaging, but I didn't see any excessive brake dust. I'm still under warranty, but i would like to have some ideas to bounce off the service writer when I take the car in.
