Well, after a few days at the dealership, I finally have the ML320 back and here is a list of what all was replaced (it may not be all-inclusive, as I left the RO out in the car):

-Transfer case
-Front and rear driveshafts and carrier bearings
-Fuel gauge
-Fuel sending unit
-Oil level sending unit
-Trip computer
-BAS/ESP module
-Sway bar bushings
-Ball joints
-Ignition tumbler

....I know I've left a couple things out, but for the most part I am now very satisfied with the truck and everything was taken care of under the dealership's "good grace" warranty.
