Journeynewbie

Recently purchased a 2010 dodge journey sxt AWD. The transfer is broken and previous owner removed rear driveshaft. I would like to just keep it is a 2wd vehicle as of right now. What steps needed to make it driveable as a 2wd? Right now makes a clunk from transfer case. Previous owner mentioned removing the coupling that holds the rear driveshaft and plating the transfer case so no fluid leaks out. Any suggestions would be helpful. Thanks
