Going to look at an 08 after my 2010 got totaled.

Hey guys I recently totaled my 2010 4.0 2wd. It had 140k miles and only thing I ever did was replace the thermostat housing.

I found an 08 4.0 with 4wd and 120k miles for around 6k. I obviously need to check it for rust but what else should I look for? I assume it is basically the same as what I had before, however, last time I bought I didn’t check anything. I want to get it right and be sure this time
