Hi everyone, this is a longshot, but does anyone else have a tapping/creaking sound from their rear floor? When I accelerate, brake, or turn, I get a creaking sound (almost like plastic flexing) from somewhere in the back. I spent way too long checking door hinges, seat tracks, sunroof, and kick panels before I realized that it's coming from the actual metal floor. I stuck my hand under the carpet and couldn't feel anything on the surface of the floor, so I jacked the Expy up and climbed underneath. Unfortunately the creaking spot is right above exhaust components and a heat shield, so I can't see it. But I noticed the floor pan is overlapping sheets of metal that are riveted together. I wonder if there's a little bit of play between panels that makes noise when the frame flexes.
I've fixed 10 other rattles on this Expedition (I made a list because there were so many), but I'm losing hope on this one. Here's a video of what I'm talking about:
Thanks!
