2019 tb custom 5.3 with 18k miles. I now have the loud Metallic click from the drivers side axle shaft when accelerating from stop or low speeds even and also on heavy breaking. I have the same amount of play/slop if I move the axle shaft back and forth in the bell housing on the transfer case. No noise in 4wheel and less noticeable in 4 auto. Looks like I’m screwed until gm finds a fix. Seems like a longer axle shaft would do the trick, idk.
