Hi all, i know this is a longshot but I'm wondering if anyone has had a similar experience and/or can share some insight since I'm a few hours from the nearest dealership. I have a 2019 STX w/ FX4, and have been hearing a squeaking that sounds like it's coming from the rear when going over bumps at low speed (it may be present but masked by road noise at higher speeds though). I searched around the forum and tried spraying silicone lubricant on the vertical rubber strips between the cab & bed, as well as horizntally all the way across the channel, but to no avail. I also tried shaking the spare tire and just about everything bolted on under the truck as well, but could not replicate the sound. I bounced on the front and rear bumpers and shook the truck back and forth with no sound, so i don't think its coming from the suspension. I can hear it when the windows are up too so I'm starting to wonder if it may be coming from the windows or sliding rear window? I know that this would be near impossible to diagnose remotely, but im curious if anyone has had a similar issue and fix that might set me on the right track. Thanks!
