My CLK has developed a noise coming from the n/s rear wheel area. It's only noticable when travelling at 50+ mph or when cornering hardish around a round-about. At first I thought it was the wheel bearing but the wheel bearing was replaced 11 months ago. So I took it back to the place that replaced the bearing thinking that if it's the bearing then they'll just swap it out, free of charge, however they claim the noise is caused by a "worn hub centre slipping in wheel bearing". Does that make sense to anyone? If so, please enlighten me!
