I'm getting some interesting noises from my S3, which I'm hoping are just worn wheel bearings and not something more sinister (and only 6 weeks to go on my warranty!). At speeds above 50 its like a constant whirring (more like someone going "oooooooooo"!) noise. It becomes louder between 35 and 40 and more vibration in the noise especially when turning - its especially noticeable if I come right off the gas at 40 and allow the car to slow down. There also more of a rumbling noise at around 17-20mph (i.e. exactly half of the speeds above). Note that the noise remains the same even if I'm not in gear. So is it wheel bearings or anything else I should be more worried about??
