So Ive had this crazy squeek in the rear(of the truck) when going over sharper bumps, and when hitting a series of bumps it was intense. I suspected the rear doors but could not mimick the sound. I did everything, latches, swaybars, cargo cover, rear hatch, spare tire and etc. After being fed up I got my dad to drive while I hunted for the noise. Turns out it was the top of the door squeeking against the weather stripping on the body. Not what I expected based on the intense noise. After giving all of the weather stripping some silicone love. the squeek is GONE!!!!! Just an FYI for all those squeek hunters out there.

 

Nice! I hate squeaks. I'll keep this in mind for something to check if it ever develops in my truck.
