Does anyone get a whining noise that sounds like power steering pump, but doesn't change when you turn the wheel. It's not when the turbo spools either. I cannot trace it, but it seems to be louder when truck is cold.

How many miles on your truck? Have you flushed the power steering pump fluid as it may be cavitating.
My power steering unit was making a buzzing noise at about 40k miles,a friend and I flushed the PS fluid with about 2-3 quarts,the buzzing noise was gone and the truck steered & braked better
Might be worth checking out.

I'm waiting for someone to say sounds like my ex-wife.
I had a noise like you described a year or two back. Sounded like a p/s pump, worse when cold and variied with the throttle. I couldn't trace it either. Last summer I had the bearings go on my turbo. Replaced the turbo bearings and no more noise.

any wiki's on a ps flush? how hard was it to do?
Before you R&R the PS pump you might try this:
With everything warmed up to Op Temps, Turn the steering wheel FULL Left & Right.. Bump it against FULL left & Right. Shut it down, let it set foe a few minutes, check the PS fluid level, add if needed.
What this does is... purges any air that may have accumulated over time & miles when the fluid level might have been a Tad low. (JMO but these Ford PS pumps are very touchy about the fluid level. Allways have been)
I've had the "Whine/Buzz" a couple times in 128K, did the above.... It worked. Works on the wife's Wind-Star too.
(Got this idea/fix from my Dealer/Service Mgr, many years ago)

My truck has around 160k miles and hopefully it isn't the turbo bearrings. I will try the P/S trick. I usually use a vacuum pump and it does a good job, but maybe this time it didn't.
