Noise coming from the back of the car (video included)

[RawrImAMonster]

There is a noise coming from the back of the car, it sounds like its coming from the center of it. I've never driven an awd car before I got this one, but it still doesnt seem like its something normal. This video was originally going to be a video of the bov, but it turned out better with the windows down. The bov IS recirculated, its just really loud for some reason.

Anyways what do you all think this noise is? Its that "roar" at the end of the video when im slowing down. It changes when the speed changes.

jack the car up put jack stands in and crawl under the car. now shake the drive line but the mounts(you'll understand when you see) the mounts might need rep;aced. If that is the problem then you can buy the mount from MachV.com.

actual name is carrier bearing

I haven't jacked the car up yet or anything, I just noticed that machv says under the description of the carrier bearings that you will hear a thump when you get on it. Theres no thump, its just that somewhat loud roar coming from the back.
