Default 2012 F150 V8 Whine-Whistle at 60-75mph

This high pitched whine on passenger side at
high speeds. It was random and less frequent now more frequent, sustained, and annoying.

I've seen a few threads on idler pulley replacememts... does that sould like least expensive start?

Truck has 54000 miles and is regularly maintenanced. Ford Customer Service reps thought I was crazy until they heard it...they thought I should wait til it gets louder? Of course they are not driving it.

open the hood while the truck is running and listen for the whine coming from the engine bay. if you don't hear the whine under the hood than it is not the idler pulley

Thanks, will try that. Any thoughts if I hear nothing?
