Clunking from a dead stop.

Only when going over large bumps like speed bumps and pulling in the driveway 

Did you have a trailer hitch in? I thought mine was making noise till I realized that was the bugger making noise.

I have a 2020 and from day one I thought my spare tire was loose. Uneven terrain, taking a speed bump at an angle and especially backing out of an uneven driveway the clunking is worse and loud.  

 

From digging around here and on other sites I found my issue was the leaf springs are slapping against one another in the spring pack, especially when they are being twisted. Dealers have packed the springs with grease which will work for awhile and once it gets dry the sound comes back. A member here had a how to to add heavy duty rubber as isolators between the springs.  I added the extra rubber between leafs and it did help muffle the sound but really never went away.  

 

You get used to it once you realize there's not much you can do and it isn't doing anything bad.  Loading the truck with weight will also make the sound go away.  I usually do 200 lbs in the winter for traction and the extra weight doesn't allow the leafs to slap against one anther when they are being twisted.  I also just installed a set of Airlift airbags and that has also really tightened up my rear end even when theres no load.  Really improved the ride and quieted up the clunking to the point its basically gone. Still need to drive the truck more but the few test drives I did are like night and day.

Old thread but my 2022 Silverado 3500 is doing this exact thing at 33k. Just started to do it a couple of months ago. Couldn't get it to do it for the dealer unfortunately but its definitely happening after coming to a dead stop and then taking off again. My old 4tunner did this bad and was fixed by greasing the slip yoke and u-joints. I can't find a single grease zero fitting under this 3500 however so I'm at a loss on how to grease things up...

 

Any of you guys that had this problem a couple of years ago find a solution?

Could it be the hill start assist holding your brakes? You said it's worse on an incline. I notice my 2021 definitely does it as well, I was thinking either the hill start assist is engaging without it showing on the dash or possibly a slip yolk issue (from recent experience) I'm new here and just spitballing.
