Rear end noise

Not sure if this is the right place but I don't know where else to post it.
My truck is making this noise its like a squealing noise somewhere in the rear. And I can't figure it out. Its only while accelerating and its not all the time. Mainly coming out of a corner or a dead stop. Sometimes much worse than others. Any ideas?

This video I found on youtube sounds just like it.

Also should note when it happens it happens for a short period of time maybe 5-10 seconds and then its gone. It almost sounds like a tire rubbing the shock but I don't see any since of that.

 

Leaning towards carrier bearing.

 

Try some lactose free fuel....

 

Any more educated guesses

 

Found the noise. Carrier bearing is shot after maybe 7k just had it replaced back in Feb or March I think. And it's toast. The rubber boot on it is torn all to hell. Guess I'll be putting a new one in tomorrow
