Have just had the offside wheel bearing replaced on my Octy RS cos I thought it was responsible for a grinding noise when I go round any left hand bend at 30 mph+. It hasn't fixed it and now I do not have a clue. The garage has checked the brakes and bearings of both back wheels and say they can find nothing wrong. The noise is getting worse and I don't want the wheels to fall off! Anyone got any suggestions at all as to what it might be.

Is car totally standard?

Have you checked that wheel nuts are all tight? I had a car once where the wheel made hellish loud squealing and it turned out that the nuts were really loose - you could turn them by hand. I could only guess that someone had tried to steal my wheel.

The car is standard, apart from a chip. Don't think the wheels are loose either as the garage have just taken them off and put them back on and the noise remains.
