Buying a yj

Hi, I'm new to the forum. I have been trying to get a jeep for a long time now and I finally am getting one. It's a 1990 wrangler with the 4.2 inline 6 and a 5 speed manual transmission. It has a hard top and hard doors and comes with a soft top and half doors. It has a lift and 33" tires on it. Other than that I don't know much about it. I hope the 6 cylinder and 5 speed are good for offroad. I have been driving a 1974 vw bus around for a while so I guess it won't be too much different as far as comfort. I read that these things get 18mpg on the highway. That doesn't seem realistic to me. The jeep is going to be my daily driver. I know to look for a slipping clutch and oil burning. How do I know if the 4x4 is working correctly? What else should I look out for? Thanks for any help, I think it's a yj.

18mpg before the 33's maybe, you will probabaly get closer to 15mpg highway.

if its a 90 and a wrangler its a yj.

Most people arn't too thrilled with the 4.2, the carb is a bit cold personalitied sometimes lol... Nature of the beast though... If you can find one with a 4.0 you may be better off, they started the 4.0 from 1991-1995. The fact that it's got hardtop and hard doors is a good trait though, a lot of people pay big bucks on craigslist for those. As for comfort, well, your going to be riding on 4 leafsprings, physical comfort isn't very great to say the least, HOWEVER, the mental comfort of knowing you got a sweet ride and your becomming a part of an entire culture is priceless!

Good luck with your purchase, make sure to check the integrity of the frame, its pretty common to have the back of the frame rust out behind the gastank (easy to see), also a problem near the power steering pump (front left corner of the heep)...

Anyway, good luck with the buy, and welcome to the forum.

As for your 4wd, have the guy engage the 4wd while you stand outside the jeep (preferably 2 low)... have him hold the brake and hit the gas, if the front driveshaft tries to spin and the front axle is trying to lurch upward (spin counter clockwise or up) then your 4wd is probably good. There is a lot of torque going to the front end and with stock springs the front axle will "warp" the springs just a touch, like an "s", if you see obvious strain where the front driveshaft meets the yoke of the differential, your probably good... Most importantly, have him engage the transfercase in 2 lo (one pull back) and reach under and try to turn the driveshaft by hand... (make sure he doesnt have the jeep on when he does this otherwide the central axle disconnect CAD will engage the front end and the driveshaft wont turn anyway... With the jeep OFF, have him engage the 4wd so the vaccum cant lock the front in, if the driveshaft spins when you try to turn it, the transfercase is garbage and completely out of order.

IF you think of any more questions let us know!

^x2 the culture is the best part of the jep worl imho, Mithuth took me thru some powerlines and logging roads in pa in a topless/doorless TJ, not long after that I caught the jeep bug hard, now I eat,sleep,jeep.

Welcome to the forum, the hardtop and hard doors go for over 500 easily.

Another way to test the 4wd is to engage it and then drive it around the yard making tight turns. If it starts binding on you and bucking a little, it's working. I've had several 258 powered jeeps, there an awesome engine with gobs of lowend torque for wheeling. Yes the carbs are much to be desired, but you don't throw the baby out with the bath water. I have a holley 470 TA 4 barrel on my 258 setting on a offy intake, it runs super. It's easy to replace the junk carb with a 2 barrel holley, weber, or motorcraft. The junkyards are full of MC carbs for next to nothing. They also make 2 fuel injection kits for the 258 for those who forget how to drive with a carb or are to young to remember ha ha. I bult the 258 in my 87 with cam, P&P head and so on, it screams. Don't miss a V-8 with this one. I've had both, the 4.0 and 258, both are great engines and I sure wouldn't pass on a jeep because it has a 258, I actually perfer them as there easy to work on. The fuel pump in bolted to the engine, no sensors to go bad and leave you walking. There an old school engine, all you need to carry along to fix them is some baleing wire, duck tape and a pair of pliers he he. The 1990 will have the good AX-15 tranny, so your good there. My old school 87 has been my most favorite jeep so far, it's the first jeep that I have built this much, it's been fun and easy and a pocketbook drainer like all jeeps. Best of all, it's not a chrysler, it's still AMC. Really look over the frame, there not afraid to rot in the front and rear. I live in Ohio and had to go to Virginia to get an 87 with a good frame. I mean I could of found some decent YJ's around here, but I was looking for an 87 AMC wrangler this time to restore. Good luck!!!

I like the idea of being able to work on the engine like I can work on my vw bus. I'll have him do all of the 4x4 tests and Ill get up under the jeep to see what it all looks like. If it doesn't already have a new carb I'll probaly just get one sooner than later before I have problems. Thanks for the help!

pics of bus? i used to really want one of those when i was in highschool but i couldnt find one. wish i would have known about craigslist back then lol. if it was even out in 2000.

dont know if you use a vw forum for info on your bus, but jeepforum here can get you through the toughest of fixes, and the easiest of fixes. youll also find a ton of upgrades from huge lifts, to free mods to make the gas tank bigger. all up to where you want to go with it.

main thing to look for is rust, someone else can chime in with the areas to double check, make sure the 4x4 works, check for leaks- some arent a big deal like a valve cover leak.. but others like a t-case or trans leak can be costly or time consuming to fix. other than that just look for the same ol stuff you would normally look for.

im pretty good at mechanics, but even still, i like to at least take a friend with me who is also into fixing junk, that way if i overlook something wrong with it, he might spot it.
might also be good for you to take a mechanic with you, or schedule to test drive right up to the shop and throw them a few bucks to give it a once over. make sure you get estimates on fixing whats wrong with it. its nice to use that as a bargaining tool.

good luck with it and i hope youll be joining us in the yj section here regularly

Hi, I don't have any pics of the bus on my computer right now. I'm glad I listened to yall about the things to look for. I didn't buy the Yj. I took it for a spin, haha, down my atv path..... It ran ok, and I put it in 4x4 high. The clutch was really bad, it had to be pushed all the way to the floor to shift, and even then it was a grind to shift, especially from 1st to 2nd. I got it stuck on purpose to see what it would take, not much. It cut off, apparently the carb has a problem. I had to drag it out of the woods with my van which it amaing offroad, it's a german thing, yall wouldn't understand. He got it runnig again by fiddling with some stuff on the carb and I sent him on his way. I'm now thinking I am going to buy from a used car dealer and get payments so I can have something nicer and more reliable. I thought about posting my bus for a trade but the love runs too deep. I'll try to get some pics of the bus up, I have some in my email for sure. I'll let yall know what happens and what I get, I'm commited to joining another culture.

I do understand, I bet my baja with the 33's goodyear MTRs I had would go just about anywhere my jeep goes now. and the best part was, the one time I got it stuck, we got 3 people together and just picked the front up, turned it around in the creek and drove it out

sounds like you made a good decision passing it up, but i can relate to the carb issue lol. damn carter carbs...


anyways, the good jeeps are out there, its just a matter of finding them. craigslist, ebay, and jeepforum classifieds.

i wouldnt go to a dealer for a yj or yj priced jeep... all they can offer you is a short warranty, but your gonna pay for it by the markup of the sales price.

but hey, its what ever you want to do. peice of mind is good sometimes, especially if its a daily driver.

i would suggest you just keep looking...

Ive been looking around at dealer jeeps. I really want the 6cyl and a 5 speed but they are the most expensive yjs one can get. I might just go with the 4cyl and a 5 speed depending on what I can find because I'm not wild about paying $3000 more for 1.5 more liters of displacement. My friend has a diesel land rover which is very appealing. I might buy a cheap yj with high miles and pop a 4bt cummins diesel in it and drive it until the wheels fall off and then swap the engine into my next victim. I don't know what to do, but I don't want to jump the gun and not get the jeep I want. Is the 4cyl ok with a say a 5" lift and some knobby tires? If so I will get one. It probably won't be the speed demon that my bus is but I can always buy a tow bar and pull it up to the mountains behind the bus....lol

Like I said, "most people arn't to thrilled with the 4.2's" ...nature of the beast i guess... So dont base all your YJ experience on that one testdrive... I've run in a 4.2 before, a great motor, some have no issues what-so-ever, others have issues but a simple carb upgrade fixes everything... So i'm not dissing those who have a perfectly good 4.2, just stating that first time jeep owners tend to turn their nose up a little when hitting the trail for the first time. There is a learning curve with em!

But hey with the 4.0... you get to mess with a brain! lol which most would argue is WAY worse than a carb... With all the snesors and such...

Anyway, sure hope you end up getting a heep, its a great world to live in, similar to the German car culture.

if you get a 4.2 id plan a 4.0 head swap ( great upgrade ) and a MC 2100 / 2150 carb swap or a weber carb swap with nutter bypass.

if your purchase a YJ. your going to learn every bolt on it. getting a jeep is not like getting a honda that you drive around with out ever looking under the hood. youre going to end up popping the hood at least once a week. and spending some time under it.

also your girlfriend / wife will wonder where all your money goes...
