Wassup!
My 2008 G8 has a humming sound around 55mph. It goes away when I'm traveling faster or slower. There is also a rubbing sound on low speed turns but not on high speed turns. It sounds to me like it could be the front driver side wheel bearing. The two could be related to the same failing part. It could also be drivetrain related, does anyone have any ideas? Has anyone had this problem?
