Front End Noise

[joshtheawesome]

When i decelerate from about 25+ Mph my car makes a harsh front end humming noise

I have video and it comes from the front end. Seems like the engine area but below that

2005 Rainier V8

Anybody know what this could be?

you really have to listen to hear it in the video but its louder in person

Check your fluids? Diff and transfer case? Check axles and passenger side disconnect.
