Geonovast Posted December 18, 2009 Share Posted December 18, 2009 or 2.8? AW-4 was never behind the 2.8 @ ax15 behind a 2.5 from factory, disputed AX-15 was never behind the 2.5 in a Jeep. That was a Dakota thing. Link to comment Share on other sites More sharing options...
freakjeep93 Posted December 18, 2009 Share Posted December 18, 2009 weve established that it doesnt seem to be stock or 2.8? AW-4 was never behind the 2.8 @ ax15 behind a 2.5 from factory, disputed AX-15 was never behind the 2.5 in a Jeep. That was a Dakota thing.

JeepcoMJ Posted December 19, 2009 Share Posted December 19, 2009 you can put all 2.5/2.8 stuff together. ALL 2.8/2.5 shafts will match each other provided the transmission, rear axle, and wheel base are also matching. also, are your 2.5 liter shaft lengths 2wd or 4wd? you don't have a t-case listed with them, so I assume 2.5..however some may not. also, ax4 and ax5's are literally the same transmission, so you can "lot" those together as well to save space on the list. I will have measurements for lwb 2.8/2.5, , ax4/ax5, np207, 4x4, d35 by tomorrow if I remember...I have like 5 of those shafts just laying around...

JeepcoMJ Posted December 19, 2009 Share Posted December 19, 2009 Add to the confusion some more. Getting a little annoyed at being doubted by my claim of a AX15 in my '89 with 2.5 I went out and checked. First moved the truck to get it out of the snow. Second raised it up high enough to get under it. Checked the manual to determine a sure fire way to ID a AX5-15. Crawled under truck.cold water immediately began dripping down my neck. Measured gearbox. 16 1/2 inches. End of fact finding tour.Scrapeing grease off surrounding area revealed a 3/4 inch (approximate) aluminum plate between tran and bell housing. Does not look original. To cold to do any more came into house and warmed up. As soon as I get the CJ3 I'm working on out of the garage the MJ is going in for further analysis to confirm a growing suspicion. Jim By the way, have 5 MJ driveshafts. They ALL have the sticker on them. Rear ones, Don't know about the front. stop getting annoyed...it's NOT original if it's an ax15. the aluminum spacer further proves this. Link to comment Share on other sites More sharing options...
jimoshel Posted December 19, 2009 Share Posted December 19, 2009 Perhaps a little explanation here of where I'm coming from, or been, might throw a little light on the subject. I drove my first Jeep, a surplus MB on grand dads farm in Mo. I was 12 , the year was 1947. He had 4 of them.They were sold in lots of 4 at the surplus auctions to keep the little people out.And to keep the auto dealers, manufacturers happy. I've been a jeep man ever since, probably owned over 2 dozen of them, MB's,GPW'S, CJ'S, FC150-170,Waggoneers, Gladiators,J10, J20.Thats not counting another 2 or 3 dozen junkers or parts vehicles. I could disassimble a CJ and reassemble it blindfolded.I never had anything to do with a XJ or MJ and was completely unfamiliar with them until maybe a year ago I bought a 89 Cherokee, wrecked.In the next 5-6 months I had 11 wrecked and 4 running XJ'S. Then in Aug this year I got my first MJ.So the point is I was not all that familiar with MJ'S and may have assumed or jumped to the wrong conclusion to quickly. I now have 5 MJ'S and a little more knowledge of them, with a lot of credit for that knowledge going to the fine knowledgeable people in CC.When I got my first one, a 1989 SB, 2WD,5speed and I assumed it was all original based on what I could see. I got a Chilton manual and checked out everything to see what I had. Which I determined to be a 2.5 a AX15 and a Dana 35. A more careful recent inspection reaafirms the AX 15 but not the motor. I'm still not sure it's ancestry but working on it. I apologize for all the confusion I created when I stated 'ALL ORIGINAL" but I'm still happy with the son of a gun and wish I'd found MJ sooner.Jim :cheers: Link to comment Share on other sites More sharing options...

I don't have background in anything but comanches, cherokees, and some VW...I'm 23 now, have had/worked on a comanche since I was 12 or 13, and I've owned over 15 MJ's and around 5 xj's. I can tell you flat out that the trans was swapped in. please don't take me as a jerk etc...I'm just telling you what it is. an owners manual can help you identify transmissions and whatnot, but it's only going to show you general information about all of the transmissions.

mvusse Posted January 4, 2010 Share Posted January 4, 2010 I still disagree with the chart, as my stock drive shaft is still 48.25" long, and the chart still insists it should be 49".

ride172 Posted February 5, 2010 Share Posted February 5, 2010 I can get the length of the LWB 2.8L TourqueFlight np207 amc20 rear axle today... But then I'll need someone to tell me a few things about the slip yoke and driveshaft lengths... I'm going to swap the axles from my 86 2.8l torqueflight np207 amc 20 into my 88 4.0l aw4 np231 d35c.... My question is will I be able to use either rear driveshaft in either truck after I'm done switching axles without having it lengthened or shortened??... I don't know how much length the slip yoke has to it... :dunno: If there is a an inch difference either way can the shaft still be used unaltered?? I'll have that measurement in a few hours once the babysitter (grandma) gets here... Link to comment Share on other sites More sharing options...
