Loud Whirrling/Whooshig sound???

I have a 99 Grand Cherokee Laredo that is making a lound whirrling sound - I think it is coming from the back of the truck. It gets louder at speed and I can't hear it at idle......what would this be? Wheel bearing?

Ignore previous poster. It's probably the rear axle. I would have it checked to ensure it's setup correctly. The rear of my 99 blew at 55,xxx miles, so it had to have been messed up from the factory. I wasn't hard on it and it was always noisy and the dealer wouldn't fix it. Oh well.
