Anyone experiencing a high pitched whistle or whine from their 5.0? It kind of sounds like a serpentine belt squeal that gets higher pitched as the RPMs increase. I’ve got about 500 miles on my truck. I can’t hear it inside the truck. I pulled into my friend’s driveway and he heard it and pointed it out to me. Once I put the windows down, shut off the radio and revved the motor I could definitely hear it. I’m curious if others with the 5.0 have a similar sound or if this is something I need to have the dealer look at.
