My car is in at the dealers right now as they are trying to trace the cause of a rubbing noise. It sounds much like a wheel bearing sort of rumble but the bearings seem fine.

The noise happens only above 45 mph and becomes inaudible above 75mph, its much worse under load up hills. Whats puzzling is that it seems much slower than road speed and the dealer is sort of disputing whether its a real problem although hasnt given up.

Im assuming because its slower than roadspeed, the issue is somewhere in the drivetrain itself.

Each time you get the noise, you get a corresponding vibration through the floor and Im not happy this is normal. Its not a bad vibration, but the reasonance is enough to give you a headache after a half hour, which doesnt seem normal to me.

Any clues what could cause such symptoms?
