Yeah Man, in it to win it, for some it's a trial by fire.
Start with more info: When you're doing what? Driving fast, slow, parking? When it's cold, hot, snowing, rain?
Is the sound localized to the front of the front, mid, or rear of the truck? Lots of things can squeak.
Is it when your wife, or dog, is mad, happy, grumpy, sleepy, or tipsy?
All of these factors affect a man's perception of his Square Body, believe it or NOT!!!
