Ok bud. Spamming the forum isn't going to resolve your issue.
Why did you wait 4 months before asking the best raptor forum for help? You asked a layer first....
We can try to help but need some more details.
What mods do you have done to you truck?
What driving conditions was the truck under when the noise started?
What components have been replaced thus far?
Have you contacted Crystal @
FordService?
I agree with rookie that it's probably an IWE issue, but if it's been at the dealer that long they most likely have replaced those.
