looking at a 89 YJ, what do I need to know?

I am looking at a 89 yj islander with the 4.2 and 5 speed. it has a black diamond 4' lift, 33' tires, 6000 lb winch. The carb has been replaced with a motorcraft 2150 and it has the Ax15 trans. Have only seen pics of it, looking at it in person on fri night. he is asking $5000. Anything i need to know and is that a fair price? Thanks for any help you can give me

Price seems good what's the mileage. is it rust free? check to see if there is any frame rot around the the leaf spring hangers and the front and rear shackles. With a 4" lift does it have a slip yolk eliminator (SYE)? From what I've read a 6k winch is a little lite I've got a 10k and really wish I had a 12k.

Take a look at the underside of the tub as well as the floor pans inside. You definitely want to take a good look at the frame where the spring shackles are as killswitch505 said.

I would look around the soft top hardware and I would take a strong magnet to the tub looking for body filler instead of metal mine was rear ended and did not find full extent of damage till after replacing soft top and lat look at the tailgate under the tailgate seal for rust

Thanks for the input. it has 160,000 miles. and I was wrong on the winch, it is a 9000 lb. I asked the guy about rust and he said he hadn't noticed any, but i will look real close tomorrow. I dont know about the slip yoke eliminator but I will find out. I really don't know what a SYE is. if it does not have one what kind of expense is it to install? One thing I have been wondering is how good the 6 cylinder will do with 33" tires. Another thing I am curious about is if the speedo is mechanical or electronic? He said most of the miles came from being pulled behind a motor home. I can see that is it mechanical put not electric. Thanks for all of the input

I've not had any problems with 33" and the 4.2 it will run 70 mph no problem but I'm on pretty flat land. when you lift a jeep over a couple inches it puts your drive line in some severe angles that can cause a few different problems. The SYE gets rid of the stock slip yolk on the tranny that allows you to run a CV style drive shaft. The cost depends on how handy you are the SYE runs 200 a drive line is 300 buck all prices are on the ish side depending on brand. the owner may have gone the cheap route and just done a transfer case drop that is not necessarily a bad solution to the to the drive line angle. I just don't see the point of adding a lift just to drop the Tcase but again that's just my 2 cents. I'm running a Tcase drop until I have time to install the SYE and one inch rise motor mounts I have both parts just waiting for a long weekend and room in my shop But if your gonna do all that you may consider an 8.8 rear end and re gearing the front end and blah blah blah hundreds of thousands of dollars latter your still not done lol. 160000 miles is not bad either way and yes the speedo manual I'm pretty sure it would rack up miles while being towed maybe some will chime in on that.

Thanks for your input killswitch. I did buy the jeep tonight. it does not have the SYE and I understand what your are talking about. I did notice that it has a vibration at lower speeds and then goes away, then when slowing down it has a clunk noise and the vibration comes back. So it looks like i will need to upgrade that. I also noticed the left motor mount is bad also. The is a little rougher than I was hoping for, but most of it is fairly minor that will not be a big expense. I was looking for a project and now I have one

I did notice the transfer case drop. When I do the SYE to I need to remove the spacers on the transfer case?

I would put it back stock if your gonna have to replace a motor mount I would look into 1 raised mounts that will change the angle of the tranny you will have to make a new tranny mount that's not hard to do but again I'm not sure of your access to tools or your skill set. Post some pics of the new ride. You will find so much info on this site and others like it. You'll be spending money like crazy I hope your wife\girlfriend is cool lol
