All 6.0 will bark under high load on/off throttle loads. Nothing to worry about, normally.

He's talking about when he is on the throttle it's making the noise. It is
not normal for the motor to do that. My dad has an 04 f250 PSD 6.0 and it's doing the same thing. Usually going up a hill with about half throttle it'll do it or when you're getting on the interstate or somethin. I'll keep you updated on our progress.
