this noise you guys talk about how loud is it and what does it sound like? my car sounds like something rubbing in the diff and its not quiet its REALLY loud bmw have tryed this fm booster and said we will change the oil again.

my first diff wasnt locking so they changed it and they never changed the diff oil like they do at 2000kms do you think this could be why its loud?
