Water pump relacement on a 5.2L V8 is indeed a PITA. That frickin', son-of-a-biach nut you refer to on the fan assembly was a challenge. I tried your method of jamming a large screwdriver into the pump pully mechanism, but couldn't get the shaft to stop turning. After exhausting all other options, and running out of patience and swear words, GarageLogic finally engaged. I removed the water pump with the fan still attached. In the process, I knifed two hoses, convincing myself that they probably needed to be replaced anyway. With the pump and fan lose, I was able to extract the plastic radiator shroud...which by the way...I have since renamed "That Black Piece of Plastic from HELL".
On the workbench, with the pump locked in a vice, the big nut gave up the battle. Installation was simply backtracking the steps. 30 minutes later I lit up a victory cigar, and declared it to be Miller Time.
Total cost was under $100. (includes a few band-aids).
If it ain't broke...fiddle with it 'til it is
