My 2024 Ram when going over bump makes clunk from rear of vehicle (first noticed at 328 miles and still making same noise at 8000 miles). Took in for warranty work and 55plus hours of effort and 12 trips to dealer still not able to find noise. Could you make a suggestion as where else to look.

So here is what was removed and driven, and noise still there:

- tail gate

- bumper

- spare tire

- running boards

- trailer hitch

- rear bumper step

- bed/box

These items replaced and noise still there:

- sway bar

- shocks

- springs

- body mounts
