A couple of possibilities, first it could be a wheel bearing and when you turn it grinds. Second it could be the brake pads, they mostly make a noise when they are low and usually when braking. I don't think it has anything to do with the rear differental. See if you can find out where it is comming from. If they put the car on a lift and say the left wheel is making the noise, have them check the other side. I don't know why but have found out that a majority of times when you hear bearing noise on one side have found out the problem is on the other side. It is not always the case but something to look for.
