Persistent rattle in rear passenger C pillar

[shigman]

Howdy. I’ve got a really annoying rattle which sounds like it’s coming from the rear passenger C pillar. I’ve messed with the seatbelt, buttoned down the jack and gasoline nozzle, put the seats up and down, banged around on panels to try to localize but nothing seems to help. It’s a 2023 35 truck. Any easy tips for dismantling the panels back there?

They just pop right off. For a detailed look, here's a video from @SoundsGoodStereo . The info you are looking for starts at 11:40.

Sweet, I guess I should have actually done some googling. I hope I find something loose in there, driving me nuts.

There's a lot of rattling that comes from the rear window assembly. Check there too. The video above shows how to take the trim along the whole back of the cab too. Lots of things in there that can rattle as well.

Yeah other than that...pretty quiet truck. Which probably makes that one rattle especially annoying. Tends to go away on the HWY as the frequency increases, but 0-40mph its bad. Sometimes even if you don't find the rattle, simply taking apart and reassembling fixes it.

I have a rattle coming from the same location in my 24’ as well. Please keep us posted if you figure out what’s doing it

Tomorrow I’m going to dig into it. Will do, it’s such a horrendous rattle for an otherwise quiet interior.

Any progress in regards to this issue? I am still hunting for the source of mine lol

Sorry guys....had other crap I had to do....broken sprinklers and stuff. I did partially pull that C pillar panel back, didn't see anything and slammed it home. Still rattles.
