ZL1 Rear end noise

Thank you ZMEnow for your answer.
First of all, I’ll change oil in the diff then I’ll see if the noise is still present.

Your point of view: It is necessary to replace all of the rear differential block ?

Almost 25000 miles depends on the ring, pinion wear if it can be shimmed back.
