Rattling in rear of vehicle or possibly the drive line

[Mikeylikesit]

I have a bone stock 2021 with 12 k miles.
A few weeks ago I noticed at low speed rattling somewhere aft of front seats. I’ve checked everything and nothing’s loose. Drive line? Reminds me of the old diesels sounding like marbles but this is more subdued.
Can’t hear anything above 30 mph or so.
Sound familiar to anyone?
Thanks for any help.

I have same issue, it sounds more like a creek than a rattle when I hear it and its more noticeable below 30 mph for me as well..

Thanks for your reply. I’m guessing others will weigh in with similar issues.
This is really nuts, but I took it out to run a few errands a while ago and
no noise. I probably drove 20 miles, made 4 stops, kept speed at 30 ish. WTF!!
How many mile on your 392 and how long have you been hearing the creak?

I have 9500 miles on my 21 non recon, its been doing that for about 5-6 months now and it seems to be louder when I first start to drive and it's not as loud after I've been driving for awhile...if I would to guess the creak noise sounds like it's coming from that hemi engine don't think it's a suspension problem but I'm no mechanic

The engine has a ticking sound almost like a valve tap and goes away in a few minutes when operating temp is reached.
My problem is somewhere in or under the back end. Thanks for your reply.
