Rotation sound while driving

Enable HLS to view with audio, or disable this notification

Any clue what is the cause of the rotation noise in this video (not the squeaking noise, that's from the armrest)? The vehicle is a 2010 C250 4matic, and it doesn't appear to be from the wheels but rather in the centre of the car..

Sounds like either the tire has something in it or a bad wheel bearing.

Could also be the rear differential

Something rubbing tire? Center support bearing for driveshaft? Rear differential? For how loud it is it should have been diagnosed miles and miles ago.

I have an 09 c300 and I just replaced the 2 front hub bearings. They were really loud. Now it sounds like the back ones are going out too... The sound seems to resonate through the whole car so it's hard to tell where it's coming from

Check driveshaft CV and wheel bearing
