I have noticed fot the last couple of months, when I back up at 10-15 mph, and turn the wheeland hit the brake the same time, I get a lot of ABS noise. At least I think that is what it is. Almost sounds like a tire rubbing on an inner skirt. If I turn the traction control off though, there is no noise,no matter how fast and hard I back up and touch the brake. Anybody elses do this? :-?
