We just shipped our 04 Limited coupe down to FL. Upon driving there is a noise coming from right rear area that sounds like a HEAVY card on bicycle spokes.
It does this ALL the time hot or cold from about 10 MPH up to 60 (fast as I dared take it for now) and gets progressively faster as speed is increased.
I took RR wheel off and examined all the components nothing loose amiss or rusted It continues to make same noise when brakes applied so I dont think it's that.
I can hear noise better with windows UP than down almost sounds like it's coming from behind the passenger seat?
I have swerved back and forth but no luck either.

I'm at a loss and dont want to give mechanic a blank check for this. Anyone have a clue where else to check?
Maybe wheel bearing? but car only has 34K on it and has always been garaged and driven responsibly
