    There are a couple TSB's for these cars regarding clunk noises. The first one basically describes a condition where a noise can occur, but there is no repair advised or required. That one is #99-04-20-002J Dated March 29th, 2017.

    There is a second advisory note that outlines a clunk when accelerating from coasting. This describes wear in the "wheel drive shaft cross groove joint". That is the CV joint at the front of the rear driveshaft, the one that connects right at the transfer case.

    I don't see any other references to clunk nose issues.
