rear bearings
 

a groan that gets louder. Put your rear seat down and that should help be the judge as the car is fairly sound proofed.

well good. next question. why does my one brake squeek when im not braking? its my left rear i believe.

It's probably the wear indicator ("chirper") letting you know you need new rear pads. If you know you dont need new rear pads, it could be that the wear indicator is bent slightly.
