i have had something similar happen to me. if the bed of the truck is bowed inward toward the cab that can cause a bit of a whine. easily fixed because the metal is so thin. happens every other time i load my dirtbike. just a guess. any idea of the general area that is coming from?

So another question there is a another whining squeaking seems like from my alternator belt seeking mostly changed the timing and water pump. Happens mostly when I'm at idle on a stop
