Hello, I have a 2000 Trans Am (Automatic Transmission) that started making a "whooshing" rear end noise. I've changed the differential fluid and the rear axle bearings but the noise persists. Here's what it sounds like from a dead stop to about 30 mph: https://soundcloud.com/achapajr/rear-end-noise

Does anyone know what it can be?

From the video it sounds like a tire, try running the car up on jack stands to see if the noise is still there.
