Noise problem help

Does anyone have any idea what this noise is? Happens at speed, most noticable around 50 mph. Happens in gear and in neutral, coasting. Happens with brakes on and off. My guess is wheel bearing. 56k miles. Thoughts?

Thanks!

It wouldn't be a bearing noise its much louder and is humming.... i would check your inter-cooler tube the big one on the right side from it not completely sure what its called... sometimes it has a by-pass leak over there also if it is leaking you could see all the blow by oil in it.... another thing could be your tires many times they get deformed and on high speeds they will make a noise (not the wheels the tires them self)...

Thanks Ruslan. Don't think its tires---just put my winter tires on a few days ago, and noise is still there. Ill definitely check IC hose, but wasn't leaning towards that either. I guess it could be! Anyone else?

does it vary with engine speed or road speed? one can rule out the other. i cant hear much in the vid except a little bit of whistling. which could be something as simple as door trim allowing air to whistle through.

if it matches road speed its something in your drivetrain. something rotating. axle, brakes, drive shaft, bearings, tires, wheels, etc...

if it matches engine speed its something engine bay related. pressure leak, valve tick, loose belt, impeeding electrical motor like a PS pump...

Yes, road speed. I'll see what dealer says since it's still under warranty...
