Weird Power Steering / Brake sound after WOT??

So I've been noticing a strange sound after a quick WOT pull. Usually this happens when we shoot across an intersection on the way to take my boy to school, or after a hard WOT pull. It sounds like the power steering pump or something, with a load hum. When you turn the wheel or touch the brakes it gets louder.

It goes away after a few minutes of normal driving, or if you shut the truck off.

Any ideas?? This is an 03 Excursion with a 6.0 (137K).

Also have what sounds to be a pulley or belt squeak that is driving me nuts. Not sure if the two are connected or what.

Thanks for any help in advance!!

Nevermind, helps to check the power steering fluid level; it was a half quart low (DOH!). Added some Mobil 1 Syn ATF. Seems to be fine now.
