Strange noise. Any suggestions?

Hi guys,

I noticed this squeaking noise a couple of days ago when the truck was in 4wd hi mode. It usually appears when I make sharp turns but sometimes I can hear it when I'm going straight at very low speeds.

It seems to coming from the left front and it disappears when I put the truck in 2wd mode...

I uploaded this a clip to youtube so you guys can listen to it your selfs. Pay no attention to the video, I was only interested in capturing the noise.

Any suggestions to what it might be?

I removed the front drive shaft today and had a look at the u-joints, the one near the t-case is bad. Hopefully I can get them heated up and replaced by tomorrow...
