Clank from rear end

[Beddow05]

* update * Took the truck into service and they retorqued the leaf springs and some other suspension components. Noise was gone for about 2 weeks but now is back. Does anyone have a solution or know what is causing this ?  Have a 2021 Sierra 1500 4x4 with 15k. Lately when I accelerate or slow down from 0-25 I have a loud metallic clink/clank coming from the rear end of the truck. Anyone have this issue and got it resolved ? I see some forums with the springs but I don’t believe mine is that because it only does it on acceleration and slowing from 0-25. Sounds like a rock being hit of an aluminum bat.
