Horror from underneath!

[shooter]

Lately all these noises have been developing. I usually get that vanos marbly noise when I start up in the morning, but recently a whining/grinding started. Needless to say I have been driving with the radio off, yeah a little ocd, listening for noises. The noises typically go away after the X warms up.

However
Starting 2 days ago, whenever the idle increases I get this horrendously loud, embarrasing grinding/whining noise. The more rpm's the louder the grind/whine. If I'm in park and I rev it up, it still insists on screaming

What is this? Front diff, T-Case...

I have video that I took on my blackberry but I can't upload .3gp files on here. Anyone know how to convert a .3gp?
