I had the same problem - turned out to be a rear wheel bearing. You could easily check it by jacking up the rear of your car. Then remove the rear wheels and start the car + put it in gear. Then step out and listen to the noises. If it's the grinding noise that seems to be emitted by one of the axels, then it's almost certainly a bad bearing
