Essential maintenance/mods?

I have a 1995 Wrangler. What do I need to do to it to keep it running in the future?

I assume there is rust... how do I deal with that?

I assume there are various components in the engine that need to be replaced... what needs to come out and what do I need to replace it with?

Etc.


I'm assuming I need to use this "Paint On Rust" stuff all over the bottom of the jeep. I'm assuming I need to clean and reseal the gas tank. I am assuming I need to run some sort of fuel conditioner/engine cleaner through my fuel. And I am assuming that that will result in a lot of crap getting deposited into my tank which might clog the fuel line and lead to more fun until the whole thing is cleaned out.

I am also assuming that I need to upgrade my air filter. The stock air filters were apparently not that great while the new ones can improve fuel economy and engine power.


Etc etc etc.


I like my jeep. I want to take good care of it. Help me out here.

Well the obvious thing is keep it maintained. Oil, all fluids, make sure belts are good. Also do what I did, replace the spark plugs, wires, caps, pretty much cheap repairs/ replacement on things that are older and or bad, it makes a huge difference. You can get rust olum and spray the bottom or I had my done by a rhino liner professional, costed me a good a bit but he did a great job and that was almost 2 years ago. I was down there the other day, and still no rust rust coming through. Pretty much just stick with the obvious fixes/repairs. Keep up on maintenance. I got a 94 jeep about today I'm going to be hitting 180,000 miles and the thing still runs like a charm.

Honestly, that's up to you I never had too but it just depends on the last time they were changed cuz they don't run low very often.

Considering that your vehicle is almost 20 years old and it is ridiculously inexpensive to do, why wouldn't you?

I saw some guy demonstrating it on the youtube video and it looked pretty simple.

Should I try it myself when I'm up for it or should I just take it to a mechanic.

Its not just the money... one of the reasons I bought this car was that I wanted to do most of the maintenance myself. I figured it would be simpler on an old jeep then on something newer.

I take a lot of pleasure from doing these little projects. I built an aquaponics system just because I felt like it... did I need to build one? Nope... but its damn cool and makes me happy. Same thing with messing about with the jeep.

That said... I don't want to mess it up horribly.


I'll get a repair manual before I attempt it. But the procedure appears to be loosening the bolts around the rear differential. I'm assuming because the jeep is a 4x4 that gear box is a bit more complicated. Then with a rubber mallet you hit the panel to loosen the sealant. Then you loosen the bottom bolts a bit more and wedge a flat head screwdriver between the panel and let the oil drain out into an oil pan.

Once the oil is drained, you remove the panel, clean it out, and examine the gears. Rotate them around so you can see if any of the gears are worn down. Then put fresh sealant on the panel, and screw it back on.

Then you open the filler port for the oil and pour that in until the oil is level with the filler port. Then you screw that back on... and you're done.


In a nut shell that appeared to be how its done.

That all sounds pretty cool. Personally I would do it my self because for me money is tight, so I'd say go for it. When I go to do stuff like that I take as many pictures I can so I know what it looked like before I put it all back together. Nothing's worse then driving down the road and something failing because it wasn't on right.. But that does spin pretty simple so go for it man. Also this forum I'm sure has something about that. If you do it let me know how it goes and I'll see if I'll do it.

No no no, don't take it to a mechanic. You said you wanted to start learning auto maintenance, besides an oil change, a differential fluid change is about as easy as it gets.

You have all the steps right, it's really not difficult and there isn't much you can mess up. Plus, it will give you the chance to inspect your gears. My 93 YJ came home with and exploded traction lok in the rear, and a tab is stuck in the spider gears. Who knows how long that's been broken but I never would have found out if I hadn't changed the diff fluid.

This is what I figured... but I didn't know whether I was deluding myself.


In regards to grease... I'm assuming a big tarp under the car is a good idea when doing this sort of thing.

Nope, just a drip pan.
