2003 Pontiac Montana diagnosing noise heard during high spe

Whirring noise heard suddenly at 60mph. Sounds lower pitch as I slow down and higher as I speed up, dissappears at 5-10 mph. Does not change if I put in neutral at 60mph or if I turn engine off at 60mph, does not change if brakes are applied, Maybe changes slightly at a curve at 60 mph. Might be coming from front right wheel area, cant hear it when sitting still and race engine. I think this is either a wheel bearing or cv joint. How can I diagnose which it is, or is there another possibility?
