I had the same issue. I found the TSB that relates to the issue that the SS has and the dealership honored the work. They replaced the fluid in the rear diff and also changed out the seals (per the TSB).

Since then, I haven't had the sound reappear. I think GM should look at extending the TSB to officially support the ZL1 as well.
