I have a 01 Jetta WE. I hear a loud droaning noise, seems to be from the rear of the car. I have had passanger even say you car is really noisy. It has 11.5k miles. Tires? Bearings? I also notice a lot of brake dust on the rear wheels, more accumulates on the rear wheels then on the front, strange huh? Any help would be appriciated. I have already once taken it to the sucky VW dealership just give the usual, nothings wrong... any ideas?
