jcComanche86lb Posted March 7, 2011 Share Posted March 7, 2011 The po swapped out the original axles on my 86 2.5 manche to some out of a cherokee. I was lucky enough to get the original axles back for free. The original axles have 4.10 gears, my question is will the ring, pinion and carrier swap over to my current dana 30 (original has bent shaft). I haven't found a definite answer on the net any help will be appreciated. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 7, 2011 Share Posted March 7, 2011 It should all interchange,do you know how to set up gears? Link to comment Share on other sites More sharing options...
jcComanche86lb Posted March 7, 2011 Author Share Posted March 7, 2011 No I'm gonna have a friend do that part for me. From what I did fine it looks like most dana 30 axles interchange but would there be a chance that the axle shafts may have different spline counts? I don't know a whole lot about axles.

Pete M Posted March 7, 2011 Share Posted March 7, 2011 all that stuff should be the same. be prepared that used gears can be a real pain to set up right and in the end may never run quiet. gears don't like changes to their operating conditions. what was it that was wrong with the 4.10 axle? I didn't quite understand that part. Link to comment Share on other sites More sharing options...
jcComanche86lb Posted March 7, 2011 Author Share Posted March 7, 2011 The kid that owned it two owners before me jumped the jeep and bent the front axle that's why the previous owner changed them out. By the time I got it it had the xj axles and crappy gears. The previous owner still had the original axles laying around and let me take em. Now I'm five to ten miles an hour faster than what my speedo says. So even if Swap both ring and pinion they may never work right? Link to comment Share on other sites More sharing options...
Automan2164 Posted March 7, 2011 Share Posted March 7, 2011 What rear axle was in it, and what rear axle is in it now? If the gears are different than stock now, how do you plan on changing the front and not the rear? What gears are in it now? Rob L. Link to comment Share on other sites More sharing options...

jcComanche86lb Posted March 7, 2011 Author Share Posted March 7, 2011 The rear axle in it now is a dana 35 and i'm guessing 3.54 gears, I can double check tomorrow. The one going back in(the original) is also a dana 35 with 4.10 gears. Link to comment Share on other sites More sharing options...
Automan2164 Posted March 7, 2011 Share Posted March 7, 2011 Ok. That helps a bit. Should be good to go as long as you have some one who is a savant at setting gears up... Because if they aren't, bad things will result. Rob L. Link to comment Share on other sites More sharing options...
jcComanche86lb Posted March 7, 2011 Author Share Posted March 7, 2011 Cool, that gives me a good starting point. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 7, 2011 Share Posted March 7, 2011 Weird the PO would swap out 4.10s for 3.55s,have you verified that the old axles are 4.10s? Link to comment Share on other sites More sharing options...
jcComanche86lb Posted March 7, 2011 Author Share Posted March 7, 2011 Yeah the front still has the tag and I counted the turns on the rear. They wanted to put matching axles. The axles came out of a 4.0 xj. So if I'm changing the gears and carrier should I get rid of the half shaft. Where would be a good place to find one?

Eagle Posted March 7, 2011 Share Posted March 7, 2011 So if I'm changing the gears and carrier should I get rid of the half shaft. Where would be a good place to find one? Why get rid of it? The answer depends on what size tires you plan to run, what kind of driving you'll be doing, and how hard you beat on it. Considering that the disconnect axles mostly stand up to hard off-roading with 31", 32" and even 33" tires and the 4.0L engine, it's unlikely that you're going to break one with a 2.5L 4-popper unless you have a very heavy foot and drive it like you stole it. Just move the sleeve over and lock the disconnect shift motor in the connected position, and forget it's even there. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 7, 2011 Share Posted March 7, 2011 The problem isn't so much the shafts,its the 260 u joints. You have to change the shafts too get the better joints,you can either get one piece axles that use 297 joints or track down some 95 YJ CAD axles with 297 joints. 97+ XJs should have the 297s and any XJ with ABS should have them.

jcComanche86lb Posted March 7, 2011 Author Share Posted March 7, 2011 Alright I don't know a whole he'll of alot about axles but I have another question. Would it be possible to cut the weld on passenger side of the pumpkin and swap axle tubes? I could make a jig to keep everything aligned. Link to comment Share on other sites More sharing options...
mnkyboy Posted March 7, 2011 Share Posted March 7, 2011 You could do it and there are shops that specialize in stuff like that but I can't see how it would be worth it on a D30. I would buy another 4.10 d30 before considering repairing yours. Link to comment Share on other sites More sharing options...
Pete M Posted March 7, 2011 Share Posted March 7, 2011 car-part.com might be of help finding a front 4.10 dana 30. be sure to look for various years since the site organizes things by part number, not interchange possibility. or you can snatch up a busted 2.5L XJ and part it out.

Automan2164 Posted March 7, 2011 Share Posted March 7, 2011 or you can snatch up a busted 2.5L XJ and part it out. Tis what I did. Picked up a whole '96 cherokee 2.5 for $400. Ran great. Took what I wanted, and horse traded it to another member for some MJ stuff I wanted. Rob L. Link to comment Share on other sites More sharing options...

Exxon Valdez Jeep Posted June 12, 2011 Share Posted June 12, 2011 eveything will swap from one dana 30 to the other. just use all the brakes from one axle (doesnt matter which one, just use all the same brakes and unit bearings from one axle). Used gears, try it. I did. Its not like you are losing abunch of $$$ doing it. You'll know relatively quick whether it will work or fail, just keep an eye out for shavings in the fluid and bad bad noises. I would dump the CAD, one less thing to fail. Search around one here, somebody posred up a part # for the seal you will need. Link to comment Share on other sites More sharing options...
