Strokermjcomanche Posted February 17, 2015 Share Posted February 17, 2015 89 Comanche 4.0 5sp 2wd 35 axle . I was wondering what is involved to convert to 4wd besides the typical shifter, axle, driveshafts and speedo cable . I haven't seen the truck as of yet to know what trans it has , can I make the 2wd trans a 4wd trans ? I already have a 231 out of a 95 xj with a 4.0 and I know there are spline count issues . Any help is appreciated . Thanks Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 17, 2015 Share Posted February 17, 2015 You need a 4x4 trans. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted February 17, 2015 Author Share Posted February 17, 2015 Gotcha , I've done the auto 4wd swap before not so much on the manual and never paid attention as to if there was a remove able tail housing . So I need a 23 spline count right ? Link to comment Share on other sites More sharing options...
87MJTIM Posted February 17, 2015 Share Posted February 17, 2015 You will want a 4wd AX15, preferrably from a 94+ XJ. This will have the external slave cylinder. Link to comment Share on other sites More sharing options...
nitroxsteve Posted February 17, 2015 Share Posted February 17, 2015 If you have a Peugeot 5 speed you can change the tail shaft housing and cut the output shaft off to the correct length. I got a housing from a CC member and cut my shaft off and it works perfect. I didn't even pull the transmission for the 4x4 conversion. The output shaft is splined all the way up just be sure to cut it to the correct length. I agree an external slave AX15 would be great but if your trans works why throw it out until you need to. I'm sure you can find a junk trans to pull the tail housing off. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted February 18, 2015 Author Share Posted February 18, 2015 NitroSteve , what is the spline count on the pukey ? Or better yet did the splines change from 21-23 in 89 . Thanks guys^^ Link to comment Share on other sites More sharing options...
nitroxsteve Posted February 18, 2015 Share Posted February 18, 2015 NitroSteve , what is the spline count on the pukey ? Or better yet did the splines change from 21-23 in 89 . Thanks guys^^ I don't remember right off but I think the pukey and early autos used the same splines and I think its the 21 spline. I know I pulled my tcase from an automatic xj with mechanical spedo gear. Ill see if I can find the piece of output shaft I cut off and count the splines. I don't think the pukey spines ever changed.

87MJTIM Posted February 18, 2015 Share Posted February 18, 2015 BA10 = 21 splines AX15 = 23 splines whether internal or external slave. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted February 18, 2015 Author Share Posted February 18, 2015 I hope it's the ax15 , but my luck it'll be the pukey . Thanks Tim Link to comment Share on other sites More sharing options...
nitroxsteve Posted February 18, 2015 Share Posted February 18, 2015 I hope it's the ax15 , but my luck it'll be the pukey . Thanks Tim I'm not sure if cutting down the shaft and changing the tail housing will work or not on the AX15 I have only done it to the BA10.

Strokermjcomanche Posted February 18, 2015 Author Share Posted February 18, 2015 Even so the ax15 will be easier to sell to someone than the pukey Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted March 7, 2015 Author Share Posted March 7, 2015 Ok , well it's the ba 10 and I'm having a tough time finding a 4wd ax15 for the 4wd swap . Can I use a nv3550 ? What is a going rate for the ax 15 / Nv 3550 ? Link to comment Share on other sites More sharing options...
87MJTIM Posted March 7, 2015 Share Posted March 7, 2015 Have you search craigslist? A search in my region (MD/ south PA / WV) has several avail. Mostly asking from $300 to $500. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted March 7, 2015 Author Share Posted March 7, 2015 Yes I have, I've had no results in the Youngstown ,Pittsburg , Cleveland areas . I guess I could make another MD run if necessary but was hoping for something closer . Thanks Tim I've got a month or two to get some parts lined up for the swap so it's not a big rush .

Futurecomancheowner Posted March 7, 2015 Share Posted March 7, 2015 I'm looking to buy a 1987 2wd comanche, but it has the manual 4 speed trans in it.. I'm looking to convert the truck to 4wd by using a 1992 AUTOMATIC xj as a donor for all the 4x4 parts. and i was wondering how hard it would be to put the automatic trans in the comanche?

You have a 2.5 if you have a 4 speed. The transmissions are different between the 6 cylinders and 4 cylinders. Your donor for the auto will have to be a 4 cylinder as well for it all to bolt up.

Strokermjcomanche Posted March 25, 2015 Author Share Posted March 25, 2015 Ok I'm going today to look at an 4x4 ax15 that came out of a 91 yj . When I spoke with the guy he said it will only fit 91 / 92 because of the different diameter pilot shaft which he said was 19/32 And the shaft was an 1/8 in longer . He also said it was an external slave setup as well which wasn't till later years ,94? It has a115 k miles on it and wants $250 for it . First of all is 250 a good deal ? 2nd: from other threads on here The pilot bearing diameter seems to be an issue when changing the trans from the pukgoat to the ax15 . I want to make sure that this won't be an issue preventing me from using this ax15 . 3rd question is there any field tests when the trans is not in the vehicle to check to make sure it's good ? Thanks in advance for all the help. Link to comment Share on other sites More sharing options...
87MJTIM Posted March 25, 2015 Share Posted March 25, 2015 I think the seller if wrong about the pilot shaft. The BA10 and early AX15s used the same bushing. It was the 94+ AX15s that changed the input shaft. Sounds like he swapped the bell housing for you already. I thing $250 is a great deal. You may want to take it to shop that specialized in manual trans and have them test it. Best to spend a little now before you install it a find out its a dud.

I already have a 231 tcase so this will be the first part of the swap . I hope it's as advertised . Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted April 21, 2015 Author Share Posted April 21, 2015 Ok well I found a complete ax15 external slave +231 tcase , Dana 30 , front and rear DS and a Dana 44 out of an Comanche all for $300 .Going to pick it up tomorrow . It came out of a Comanche with a rotted frame . I don't think I'm missing anything . I figure the ax15 was changed at one point being it's external slave .
