some kind of problem....
 

The other night after a party or 2, i went to drive my car back to my girlfriends place when i started hearing a very low but definitely noticable hum. the faster i go, the louder it gets. Im not sure what it is, but was wondering if anyone else on here experienced this. is it a bearing possibly?? anyone have any ideas lemme know, thanx for the help

yeah, sounds like a whell hub... very common in our cars...
