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!!
