Clunk noise from rear?

Hi,
My truck has developed a clunk noise from the rear when going over small bumps like the end of my driveway- I would say its both sides since it does it when I am leaving\ coming home so I am on a slight turn. 2025 4x4 with 900 miles

Thanks for any insight.

The rear axles use C-clips, during low-speed turns with small bumps the axle shafts can shift slightly and cause a clunk due to the small amount of in/out play they have. It's also possible it's the leaf springs making noise, but my money is on the normal axle play due to the C-clips.

Some owners have reported that this TSB is still active/applies to the 3rd gen - 17-NA-394 1..5

Other owners have had good luck with Spring Things - Leaf spring squeak fix, squeaking leaf spring fix, suspension squeaks | Spring Thing

So there are options if it is coming from the leaf springs and not from the axle shaft play.
