I have a new F-450 Super Duty with 14,000 miles on it. I was pulling my 30 foot gooseneck with a good load. I stopped for dinner and shut down the truck after about a 2 minute idle. When I started back up...I now have a high pitch whistle (kind of a squeal) only at certain times when accelerating or decelerating. I also have a slight rumble when accelerating now. Any help would be greatly appreciated. Didn't sleep all night thinking I blew my turbo. Thanks in advance.

Sounds like an exhaust leak to me.

I Have A F-350 And While Towing My 11k Pound Trailer Uphill I Had A Turbo Seem As If It Was Over-revving. I Took It To Ford And Of Course They Could Not Find Anything, Or Did Not Look Hard Enough.
The fan is clutched. It will make a horrendous howl. My neighbors does this under load at 60+. Yet mine doesn't make the same noise. Usually a whistle is from the turbo so as noted that could be a source for noise also.

It's probably the transmission cooler. If it was a turbo you would not be driving it.

Mine did that also, squeeling. Ford dropped the cross member; drive line; transmission;etc to get to the "Y" below the turbo on the exhaust which was leaking in the white smoke test and was causing all this noise. They had my truck for a week getting parts from Detroit. No more squeeling. Did the venturri also while it was there. I have 39,800 miles on my F450 King Ranch at this time.

I think I am experiencing the same thing here. I have a groaning sound at about 1900rpm. Initially this was heard just a few times, now it's all that time. Less noticeable once I get moving and the truck starts warming up. It's not the fan, as I am used to hearing that and know what it sounds like. I have taken it to the dealer and they are ordering exhaust parts, but I wasnt able to talk to the tech to see what was ordered. I think they are ordering this crossover that you mentioned. Also, there is an occassional squeal now; kind of sounds like a fan belt squeal , but more intense.
I read in these forums where people are suggesting the groaning sound that I am hearing may be normal fan noise, heater core hoses and elbows under the air box; but this noise is something else, it's more like a groaning or moaning sound, almost similiar to a bear groaning.
Does this sound about what your truck was doing and did the exhaust parts fix your vehicle?
Does anyone elese out there have any information about his crossover member for the exhaust?
