I really feel for you on this project. I went through something similar with it overheating when the A/C was on, it ended up being electrical. Obviously this is not your situation, but I did try five set ups, three electric fans and two different clutch fans.
I'd guess water pump at this point, too. Changing all the fans I had made very little difference in temp if any in my '03.

Yeah I've seen impellers slip at higher RPM's on the 05 Jeep Wranglers I used to own.
I even knew of one guy that slapped a new water pump on, had drastic cooling issues, replaced everything else with no change, finally pulled the pump to find the impeller loose on the shaft. Then another guy that was out on the trail and BOOM instant overheating issues on his 97 TJ. Nothing helped so we towed it back to camp. First thing he went for was the water pump as he happen to have a trail spare. Sure enough when he removed it the impeller was basically gone!! It had been eaten up by corrosion over the years and finally it gave up the ghost out on the trail. He swapped it out, and finished the weekend of wheeling without anymore issues.

I'm will to bet if I pull the fan, and belt off that the water pump will have a wobble to it. Either way I'm going to slap on a new water pump, and since I already have I might as well.

Thank you. Haste makes waste.
Yes, I responded hurriedly and made a mistake. I meant to say fan clutch and water pump should be replaced together.
As long-time contributor Savannah Buzz said - "An important point, if clutch or WP is changed at this point, (180,000 miles) the other will likely fail soon after. Both have been bonded together and danced around the floor for millions of spins, and have grown used to each other's warts. The will be micro imbalances with just one new part, and the old one doesn't like it. If you can, change both. Or budget for second one."

IMO the best fan/clutch combo is a new earlier D2 fan with new clutch of choice as cost much less than the 03-04 combined unit.

My new fan will be in today, and I have the water pump in hand already. I'm hoping to get started on this project tomorrow, and also hoping for good news after I'm done.
The wife and I decided if this doesn't fix the issues that we're going to put the Rover aside for the time being. We have just about 2 weeks before we leave with or without the Rover.
