Bought me an old comanche

Hey guys so I recently purchased a 1990 jeep comanche, havent picked it up yet though. I bought it from a guy who seemed very knowledgable on it and does a bit of work including leaf over, extended driveshaft, new axles u joints, brake lines, ball joints and axle seals were all done fairly recently.

I plan on it being a DD/bush truck when going camping or fishing. I dont have much experience working on vehicles, but im always willing to learn. Right now i have a 2012 ram 1500 that ive done a bunch of things to but I need something a little more fuel efficient and something i dont care scratching up in the push and just having overall fun with.

Ive ordered new ebrake cables and turnsignal housing that ill put in when i pick up the truck, because i need to have an insurance inspection up here in Alberta.

Anyways its a 4.0l, he put different cherokee axles on, not dana 35s not 44s, what other axles are there? haha newb question im sure! Also what trannys does it come with? I know its a manual 5speed and he told me which one, but i have a bad memory

Main question is, what maintenance should I do to it when I do get it? fluids? spark plugs yada yada?

probably have the 8.25 axles, and i think that would be an ax15 transmission. i would recommend changing oil, differential, tcase, and transmission fluids. i also changed plugs, plug wires, distributor cap, and rotor bug when i got mine. you should also check out comancheclub.com and sign up over there. its basically the jeep forum for comanche owners. welcome to the mj family!

i think most companies that make lifts for the mj have an option to select the 8.25 axle when ordering it
