New Wrangler Owner

I have always wanted a Jeep Wrangler and finally this weekend i got one. It is a 1993 4.0 6 cylinder with 108,000 miles on it. It has some lift to it not sure how much but it is plenty for me. Cosmetically it will need new front seats and sliders, a new cd player, it has a hole in the body i will need to patch, and i think i will get some new seat belts. Of course thats just for starters, i already have about a 5,000 dollar wish list in my head but baby steps.

Mechanically I'm not sure what all it will need. I know it is leaking a bit of oil from what i think is the oil pan area. I will attach a photo of it. Also when coming to a stop it does a kinda weird jerk thing, it is very slight and may be nothing but i thought it was worth a mention. Is there any specific problems i should look out for?

Photo of it in the driveway.

This is where it is leaking from. Could this be the rear main seal or gasket? I have read a bit about it but not sure if this is where it is.

Thanks for looking, look forward to spending many hours on this forum.

probably rear main. common leak. might give more detail on the brakes. things that go bad are just the common every day stuff. u-joints, unit bearing, and the dana 35 rear end. mine is a 93 also. great jeep. yours looks a whole lot better than mine.

That what I thought. Does anyone have a link to a write up of how to replace it? I searched but can't seem to find one. Thanks

Good Looking YJ... Just wait, that 5000 wish list will soon turn into a 12000 dollar one shortly. I had issues with my brakes a bit ago wanting to grab to hard and now they want to act up with loss of pressure. My plan is a upgrade that many people on here do that is to put a 95 wrangler brake booster and master on her to see if that will make my rig happy.

As far as leaks they are common but other than replacing gasket to gasket on every part of your rig just see what is loosing fluid faster than others and you can figure it out.

Personally, neither book is great, but either is better than nothing. Ima chiltons fan if that really means anything.

Rear main as I see it is easier to replace by removing the engine, but it more involved. If it is a one piece, definitely remove the engine, if two piece you can remove them but may require some talent and maybe a tool. Its difficult to replace the seal while the crank is in place because of the tension; but can be done.

That picture of the driveshaft... What is the fluid on it? It almost looks like water from the exhaust since it is right there. It doesnt look like trans fluid.
Gotta stand by all you cool guys... Maybe it'll rub off?!

Nice looking Jeep. If its just a small drip drip I would not worry about it. Just watch it and see what happens. Mine drips about four or five drops a night from somewhere.

First leak doesn't look like a rear main. Clean everything off with degreaser and see if you can find new drips after that. Second pic looks like a tail shaft seal.

Thanks for all the replies I really appreciate it. I cleaned the area of the two leaks with some degreaser like someone suggested and it turns out the second one I posted wasn't a leak as it only happened that one day, I think it was just water like was said. I will get some better pics of the first one I posted later today, as it is still leaking. I want to know if it is a rear main seal before I try to replace it or have some one replace it.

Also after driving some more it turns out the "jerky" feeling is actually more of a grinding and it is coming from the rear somewhere. It only happens when coming to a complete stop I would say under 5-10 mph. Could this be something in the rear diff or is it more likely the brakes?

I plan on doing a complete tune up and fluid change since I don't know the last time any of that was done. I also want to check if they re geared the diffs with the 33" tires they put on. Do I just need to count the teeth on the two gearsand divide? Also if they didn't re gear is it imperative that I do it or is it just recommended?

Last question for the day. When it comes to oil pressure where is a good place to be? When I first start up it is at 40 then when it gets warm and sitting at a stop light it goes to twenty and gets higher as the rpm get higher. Around 1000 rpm it goes to 30 then higher than that it goes back to forty. Is this where I want to be?

Thanks for all the help guys like I said I really appreciate it. Sorry if I asked questions that have been beat to death but I have searched a lot and found some of my answers but just not all.

i would say if its only when slowing down like that then the problem is you need new shoes and the drums turned in the rear brakes.

the oil pressure seems fine.

93 is a great year for the yj, i bought my wife one and it lead to me having to get a yj also. great jeep though.

is that stick or an auto tranny? you count the teeth and then divide the larger one into the smaller one, if i remember right. try it either way and you will know the right onw because the other number will be crazy. you should have something like a 3.07, 3.55, or 3.73 though with a 4.0 engine.

also, the reason i came to post, you can go to morris4x4, i think, and down load the factory service manual in their tech section.

here is the link:
