Any body else have this noise loud clunking rear just pulling in driveway or over small speed bump 2023 Chevrolet Silverado 1500 ? Took mine to Chevrolet dealership and they said no problem found . I’m seeing on here some people are saying the rear leaf springs are the problem . I now ordered and installed spring thing.com kit and installed it and the rattle clunky noise is completely gone, don’t waste your time going to chevy order this kit and in 20 minutes it’s fixed

I heard something on my 2023 1500 LTZ going thru a potholed parking lot. Wasn't really sure what I heard as it surprised me. I haven't heard anything since then.

Same here.  I also get it often in the 1st to 2nd gear shift.  While investigating, I found my leaf spring bolts on both sides and the shock bolts were loose.  Tightened those to spec and the feel firmed up quite a bit but still get that clunk.  I have wondered if it's the tailgate but there doesn't seem to be any stoppers or way to adjust.  Not sure what else to check.
