Guys not sure what think on this one. I have a whistle wine noise. It just started this I have no idea why our what caused it. I haven't drove the truck in about a week I thought it was a bake but it's not. It only does it when moving and it doesn't get much louder at any point. If I'm doing 5 mph or faster it will do it coasting or accelerating it doesn't matter.
Any idea here I'm lost as lost . Truck is deleted with innovative tunes.
thanks.

 

sure you are not hearing the turbo? If this is new then it might be your downpipe is leaking a little. Check all of your exhaust components for soot.

Assuming you are hearing it from the engine bay?

 

No defiantly not the turbo, i guess the word squeaking or squealing might be a better way to describe the sound.
it does not do it all the time it started on my way to work today. And just quit after 5 minutes!
I'm thinking its in the drive line?

 

Brakes is where I would start based upon the new information.

Start with the fronts as they wear quicker. It might be getting close. I'd recommend pulling the wheel off at least one side and inspecting the pads for wear.

You can pretty much do that without removing the calipers.

 

i was thinking it could be that but it doesn't seem to be i just put brand new EBC brakes on it all the way around, aprox 1,000 Miles ago.
Could it be a Ujoint? and why would it go away and come back at random times.
I took a video but can't seem to get it to upload, is there anyway i could email you the video? if so PM your address and i'll send it over

 

PM sent. ujoints usually act differently then what you are indicating.

Will listen and see if I can tell.

 

I had the same problem and it was a partially stuck opne ERG value that whistled like a train when accelerating
