89 MJ

I wouldn't look into it that much. Chrysler reused a lot of the codes over the last few decades.

I think I'm seeing a factory sport bar too. Plus red bucket seat interior and a tilt column. Nice truck!

Pics of the hitch on my car for comparison. Looks similar, other than the plate on mine. Also, I’m a little jealous of the shiny paint.

I will get pictures of my hitch shortly for comparison. I wish you luck on the wiper arm hunt! You saw how well my hunt is going for that haha

4wd All terrains or mud terrains?

I can only answer question 4. You should be fine reusing the axle bearings and seals provided they are in good shape.

Yeah, this is definitely my fault, and I will gladly take the blame. In my defense, though, I did warn you that it was going to make you both want one even more!

Ooooooh yeahhhhhh!

Spal is good for fans

I would suspect that there is a write up on that in here somewhere: https://comancheclub.com/forum/10-mj-tech-diy-projects-and-write-ups/

Welcome! Feel free to start a build thread to keep us up to date with the progress.

How you drive it is going to be a large factor. You can also get upgraded parts for D35s too.

Make sure you're alternator can keep up with whatever you do. I'd recommend the stock 7 blade mechanical fan with a new fan clutch for starters. The late XJ efan is an upgrade over the Renix efan too.

You'll have heat soak problems without it. Can confirm from experience.

When I got it home my 15 year old daughter fell in love with it and wants to make it her first truck. We'll see. CC is Awesome! Why?- I have many future plans for this little MJ; exocage, floor boards, LS swap, long arms, frame stiffeners.... Everything I plan to do has been documented on CC by someone before and is great motivation for what can be done with enough effort. There is something about this MJ that I really like. Congrats on the MJOTM!

Ah yes, welcome to Jeep ownership

I’d remove the supports, weld in new keyparts floor pans, then put the supports back in, after they were sandblasted and primed with a weld through primer.

Some AMC goodness here. There’s a vintage themed diner in Tucson called Little Anthony’s in Tucson that has the Pacer from the movie Good Burger at it. @eaglescout526 was in town, and he got to put some miles on this fine specimen too. Always good to chat with friends, especially about AMCs!

I ordered the Dorman one and used the cap a few years ago. My tank let go, it wasn't the cap that let go from the pressure. That could've just been a bad tank though.

I’d start by double checking the intake and exhaust manifold bolts. They have a tendency to loosen up over time. Id also make sure that the IAC and TPS are functioning correctly. Just because they’re new doesn’t mean that they are good.

Most definitely! Also, I got a thumbs up from a guy in an MJ yesterday, which was super fun.

They were such a high performance racing vehicle that the 4.0 would've been too fast for the SCCA racing, so they had to use the 2.5L instead. Or at least that's my story and I'm sticking to it

Well, two(ish) week update of driving the car. It's been a daily driver for about a week and a half and I am very pleasantly surprised. It gets warm if you have to sit through the same stoplight multiple times, but otherwise she lives between 195 and 210 degrees. It is absolutely hilarious to park this old thing next to all of the fancy pants cars that a lot of college students have. Or even at apartments, the thing sticks out like a sore thumb One of the best parts is how comfortable in the car. I can judge it well and get close to stuff and I feel safer in it than I did in my more modern school vehicle. Best part is everyone's reactions to the car though. Almost every day that I have driven the thing, someone either asks what it is, thinks its super neat, or has stories about one from 30+ years ago. It has been a ton of fun.

Same experience first. My truck would need to sit pretty much all winter for me to need to prime the fuel system. And I've never seen a fast starting race car either...

IF I recall correctly (that’s a big if) it’s because the computer doesn't remember which cylinder is supposed to fire next after being shut off, so it needs to turn over for a while so it can determine which cylinder to fire.
