RAM 2020 Crew Cab 2500 Mystery Body rattle

[Mark364]

I have a new RAM 2500 crew/ 4x4/ 6.4 gas it has 1000 miles on it. I am getting a rattle like a loose spare tire
or something heavy / thud more than a light item rattle. I have looked everywhere. I saw an older thread about
the same thing. Has anyone found out what this is ? I have not been back to the dealer because my truck spent it's first whole week there
because of tire pressure sensors. Any help would be appreciated.

I have the same issue on my 2020 2500. I have the Cummins. Mine seems to be coming from the front.

Same issue on mine from the front. Seemingly when the suspension reaches full extension on a front corner there is a popping sound. From what I've found it can be the cab mounts, or a improperly torqued bolt/nut on a front suspension or steering component. I have yet to take mine to the dealer to get it addressed.

There are many other threads about similar issues it's most likely the cab mounts.... most problematic Noise is from rear cab mounts and some are from front

Is there a seperate one for the 3500?

Dang, so are these replacement body mounts an updated design?

Is there a seperate one for the 3500?

I looked up the replacement mount. It states it doesn’t fit the 3500. Do we know if there is any difference with these mounts, or is this just a system error/omission?

I have a 2020 2500 that had the rattling/ clanking / banging noise coming from the rear in the vicinity of the C pillar. According to the the dealer and mfg TSB they felt it was the body mounts. The dealer replaced them 2 weeks ago and it seems to have fixed the problem...so far.
