high pitch noise
I got a high pitch noise under the hood of my 2007 f-250 when i pull my toy hauler up any size grade. It sounds like a bearing going bad but the dealership says it is a belt slipping. I dont think its the turbo because it does it when the truck engine brakes and the turbo is not engaged. Please tell me that the dealership is wrong because they are jerks.

Go read these two threads and then decide if your noise fits the descriptions - then go tell your dealership they are correct and they need to figure out WHY the belt is slipping since nobody else has figured it out yet.
