08 Superduty whistles / squeals when accelerating over 2000 RPM's
I have noticed in the past weeks that my 2008 F250 squeals when I accelerate and the RPM is usually between 2000-2500 RPM's. If I let off or "floor" it, the squeal goes away. It is very loud, not like a belt or air whistle. I don't really notice a power performance differerance. I was thinking it could be turbo related and maybe it has more to do with the psi of the tirbo and less with the RPM's.
ANY IDEAS???? Anyone else have something similar? Warranty just expired 03/22/10.

I wouldn't think a leak, beacause he said when he floors it it goes away. If it was a leak, I would think the whistle would get louder with more pressure...
Just speculating here, but maybe a turbo bearing? That is what happened in my 6.0. It would make this whisteling sound... needless to say I had the turbo rebuilt.

Mine was doing the same thing and found out it was the down pipe/y-pipe.See if it does it especially after sitting at an idle for a few moments then it gets loud when you pull out.Mine was stretching at gasket when idling and did not do it when moving.If this is it they will have it for a day.No cab off but a tranny drop.I thought it was my torbo at first.Hope this helps

I don't think it is a belt issue. All belts seem tight. It only happens when accelerating and it has become worse over the past week. At first I thought a simple hose leak but now it is loud! When I accelerate, everyone stares at the noise and it is not a "pretty" whistling noise but more of a loud high pitch squeal. I think maybe turbo bearings but I was hoping someone else had similar issues. It only has 32,000 miles. My first Ford and I am a little taken back if the turbo has already gone bad.

Wouldn't an exhaust leak be continuous?? This is only when mildly accelerating. Once I reach 55 or so and I am just cruising, you can not hear it at all. You also can't hear if you take off real easy or take off real hard. It is only when normal acceleration is happening.
