Differential Whine: Fluid or Bearings?

Hey guys, I believe I have a whine from my differential and the recording is here. Any help to identify the root cause is appreciated.

The prior owner claimed to have changed the diff fluid 15K miles ago and upon inspection the diff fluid was dark so that's not a good sign. Thanks!
