Had a similar problem with my car. It turned out to be the power steering unit, ONLY when turning right. There is a TSB on it but can't remember what the number is. Something to do with a resonance set up in the return line. It has since started again and I'm going to try Mobil 1 Synthetic ATF in the Power Steering to see if it helps.
