As of today after taking a turn a little to fast i get a po/clunkp from the rear end in harder turns. I dont know what thims may be, but have gotten a driveshaft under warranty before since it was twisted. I've never heard it till today but almost really scared me well.

 

Do you have the limited slip? If so sharp turns can cause noise from the dif, some models required a limited slip additive.
You might also want to check the carrier bearing if it has one.
Hope that helps
