I finally replaced the water pump on my ZJ.
There was no need in removing the AC, PS, ALT or any brackets. I removed the fan shroud & pulled it up to access the fan nut wrench % tap from hammer counter clockwise & it came off. Then, I removed the lower radiator hose, unbolted the pump, tapped out the bypass line, loosened the clamp on the upper hose, twisted the pump a bit & pulled up from the bottom & out it came.
I had to park slightly uphill & remove the radiator cap while idling to allow all the air to come out of the system. Had to add about a gallon of antifreeze while "burping" the system.
Everything went great & the ZJ runs at a steady 185 or so even when going up long, steep grades. Also replaced the serpentine belt.
