Rolling down the road at just about idle, somewhere in the 20 mph range, if I give enough throttle to hold 1000 or so RPM, the truck makes this awful squeeking sound that sounds like a rolling wheel bearing about to go out completely. Let off the throttle or give it more throttle and it goes away. Any ideas as to what this may be? Driving me nuts and I cannot locate the problem because it only happens when the truck is rolling and I am away from home with no help right now. Thanks

Maybe its a loose clamp on you intercooler lines where the rubber connections are? And it only does it when its starting to make boost?

I had similar issue. Found out it was my idler pully.

Loose exhaust making funny noise. Thanks

did you figure it out? loose exhaust pipe making noise?

would have thought it would be related to a bearing noise like: carrier brg which would only make noises when moving

Well I did think it was a bearing at first because it had that rotational squeek you know, like you could hear it going round and round. The thing was that when you let off the throttle it would stop squeeking even though the truck was still rolling. I got under there and discovered my exhaust needs some sprucing up. When it was straight piped some of the hangers were eliminated and it left room for play and it squeeks. Nothing some stacks wont take care of!
