My 2018 driveshaft pops every time there is a change in the torque. GM replaced it once and it still pops. The service manager says it's that there are several beer cans going on. The main shaft has sleeves pressed in to each end and welded. He says it's the sleeves moving inside of the main shaft, yet, they're welded... I am waiting on mine to grenade before GM decides what to do with it. Also according to my service manager the HDs have the cardboard in them to reduce noise.
