Default Noise from under car (listen to it)

Suddenly I'm getting a noise from under the car that sounds like as if it has snow tires. You can hear it best at 20mph. Here is what i tried so far but the noise is still present:
* While driving i put the car in neutral.
* Turn the ignition off while driving.
* Drove on grass (tire noise).
* Checked fluid in rear.
I took a video under the car with it jacked up while i spin the tire (both sides sound the same). Like i said it sounds like snow tires.

Hate to tell you but that sounds like an axle bearing is going bad........... Ask me how I know.

Since it sounds the same on both sides would it be both sides ? I had both axles replaced in May of 07 and axle bearings in April of 09.

If you spin the wheel and hold onto the rear springs you may be able to pinpoint it better. Sometimes wheel/axle bearings can transmit noise around the car and sound like they are on one side, or the other, or both. If a bearing is bad you can usually feel the vibration most in the spring near it.

Went to the dealer today and was told the carrier bearings and pinion bearing are bad. They are covering it under warranty because its been less than 10k miles since they last worked on it. I guess i got lucky on this one, just hope they install it right..
