Another Overheating Issue

Hey Fellas. Just need a little help. I have read damn near every thread on this overheating issue. In Georgia and high is maybe 80 degrees. Yesterday the temp gauge went all the way into the red sitting at idle and did the same today. Luckily I was near a restaurant and the daughter and I just went and had dinner while the jeep cooled down. I have noticed that I have been getting some bearing noise coming from the engine (sounds like damn chipmunks). Put in a new 180 thermostat, burped, fan relays and still rising temps. I'm assuming its the water pump bc of the bearing noise. Any help would be GREAT!!!
Thanks!

Take the belt off and feel for play on the water pump

Am I checking to see if the whole assembly is loose?

So the black bearing has a little play. I guess hence the the chirping chipmunk I hear. Is that enough to make the water pump go bad? The temp gauge was completely touching 245 degrees at one point. Of course, once you start driving the temp goes down. Thoughts?

You mention fan relays but are the fans running when at temp? The only thing that stops being functional once driving would be fans, and you mention the temp goes down once driving

Good point.

Was the thermostat checked as well? Nonetheless the pump shouldn’t have any play.

He put In a 180 he says but from what I’ve seen they are issue prone alone.

The water pump shouldn’t have play though but I don’t believe it to be the main over heating issue. Also I would think the thermostat isn’t it, it would cause over heating regardless of moving or not. The radiator is doing its job at speed

Thanks for all the feedback fellas. These cooling issues drive me crazy. I've had bad thermostats in 100 degree southern weather and the temps at idle have only gotten to 220. Now we have 80 degree Ga weather and the damn thing hits 245. Even if it was just the thermostat, I've never had a temp spike like that but once years ago driving down the highway and the temp wouldn't lower (cant remember the solution). Hopefully its the water pump, ordered from HHP and will be installed along with a paramount valvebody. In regards to the fan relays, the fans were running at temp. I swapped them along with the thermostat, trying to diagnose with the cheaper items first. Damn chrysler wants to charge me $1000 for pump and install. I got a local performance shop, Injected Engineering, doing the installs next week for less than the chrysler cost.
