Check out the diagrams (Below). Please let us know what you find.

There is a way to tell if it's the bearing. From what you say though by turning the noise change's that is usually the front wheel bearing are you sure it's the rear?Also do you have a jack and jack stand's?

Let's start in the rear jack up the rear of the car with the car in park and the front wheels blocked. So that the rear wheels are off the ground. Make sure the wheels are securely blocked and your on a flat level surface. Then put the car in neutral then go to each rear wheel and spin it as fast as you can with your hand. See if you can hear any bearing noise also hold the rear suspension on each side while spining the both rear tire's. Compare each side to each other. Let me know what you find. If you have a bad bearing you should be able to feel it or hear it.
