So I replaced my thermostat before my last trip, the thermostat itself was bad, but i changed it more because it was leaking, well my jeep is leaking again. See below

If you can see, it's under the thermostate and above the water pump. I've replaced both. Which one do you think?
Also some oil, I'm pretty sure it's power steering fluid is leaking from I think my box, and dripping down my pitman arm. Is this a sign my box is bad? I was low on p/s fluid and filled it up last night, but my jeep still creaks when i turn. Broken box? I was thinking getting a durango box and a bracket from JCR if it is, but i just wanna see if there is something else y'all think i should check first.

I hear ya man. Leaks suck. Did you check your housing to make sure it didn't crack? I know these t-stat housings will crack easy when you're torqueing down the bolts.
Mine leaked in the exact sport.Make sure you did not get the gasket jacked up on the bottom bolt when putting it in. I had to do mine twice before it stopped leaking.
I lightly sanded both the head and the housing and used the grey water RVT with the gasket to get it to finally stop leaking.
