My buddy just bought a 1993 Jeep Wrangler Sahara 4.0 L manual from a dealership in PA, we took it out the day he got it to test out the 4wd in some mud and come to find out it won't work. It shifts into 4wd high and low, with some trouble but, it shifts and i drove it on the road and one time in 4 high it felt as if it kicked in and when i shifted into low it crawled like it was supposed to, but when taken on the trail only the rear wheels spin. I have heard a few things about vacuum lines to the transfer case, but i have no idea where they would be or how to fix them. Pleas help me out because my buddy would really not like to make the 2 and a half hour trip back to the dealership for this problem. Thanks

Re: 1993 Jeep Wrangler Sahara Transfer Case
Sorry, but my solution would be to take that drive back to the dealership, if he has a warranty. This is a hands on type deal, you have to trace everthing with your hands. Now it sounds to me like it could be in the electronics. You have to go to the differential, find the vaccum lines, if equipped, some are not, then trace them back to the motor and make sure they aren't cracked or broken. I hope this solution was helpful, please rate. Thanks

It's time consuming but not difficult.If you are not a do it yourselfer take it to a reputable mechanic.If you are then get a relevant Haynes repair manual, a ****** jack and floor jack, a set of standard and metric sockets and wrenches, a buddy to help balance the ******/transfer case when you pull/install them, a smooth surface to work on ( even a 5/8" sheet of plywood will do) and pick a nice day to do it. An air compressor/ impact tools will save a pile of time and if you want to change the oils, on my Jeep the transfer case drain nut is 30mm while the ****** drain is a 15/16".
Hi, Jeep offers a free download of owners manuals for '04 and newer vehicles. For older models, you can purchase a manual. Log onto this Jeep site to order one. Let me know if you have any trouble finding the manual. Good luck! http://www.jeep.com/en/owners/manuals/index.html
Hello grega1967, your Jeep Wrangler came from the factory with gear oil in the axles and manual transmission, but the transfer case uses transmission fluid. It is a NP231 and your axles are Dana 30 in the front and Dana 35 in the rear. They should have a 4.10 gear ratio due to you having a 2.5 liter 4 cylinder.
Hi there.A auto parts store or a dealership service department can help you determine the type of fluid recommended for your vehicle.The fill area is also the full mark,when adding fluid to the transmission or transfercase the fluid will come out of the fill hole and thats when you will know it is full.Its hard to tell how much fluid is is needed, every vehicle is different,but I believe the transfercase is between 2-3 quarts and the standard tranny is between 4-5 quarts.Keep your receipt and whatever fluids you do not use you can return.Hope this helps.John.
It sounds like your driveline to the rear wheels is broken. Could be transfer case output shaft to the rear wheels has broken. Try disconnecting the rear drive shaft and see if you can turn it by hand with the transfer case engaged in 2WD. If you can turn it while the Sahara is in gear, the output shaft is no longer connected to the engine for some reason.
