90eliminator Posted August 25, 2009 Share Posted August 25, 2009 So i just installed the sye on the np231, all went well I have a 6" lift.... but now I'm into the driveshaft problem...its a 92 xj with again 6" lift and an 8.8 rear... I've heard that I can reuse a front driveshaft from a xj/mj and have it lengthened... any problems with that...? or any other ideas out there....thanks y'all......

jpdocdave Posted August 25, 2009 Share Posted August 25, 2009 front d shaft is a good way to go, it may need to be shortened, i don't remember. Link to comment Share on other sites More sharing options...
89eliminator Posted August 25, 2009 Share Posted August 25, 2009 isnt the 8.8 a flanged yoke? the front d-shaft wouldnt work then. Link to comment Share on other sites More sharing options...
jpdocdave Posted August 25, 2009 Share Posted August 25, 2009 couldn't you get a u joint that adapts to that flange and then bolt it on? just like a 1310 to a 1330 u joint. i've never done it, good point. Link to comment Share on other sites More sharing options...
Motion Offroad Posted August 25, 2009 Share Posted August 25, 2009 You need to get the spicer yoke (spicer part number 1379) for the flange to adapt a standard u-joint. At 6" of lift in your XJ, you'll need to have a XJ 4.0L AW4 equipped front driveshaft lengthened. The front XJ shaft really only works with lifts upto 4".

ren Posted August 25, 2009 Share Posted August 25, 2009 You can try to find a 2WD Xploder in the wrecking yard. That's what I go the flange off of. The U-joint is a 1310, and the drive shaft needed to be shortened about 2", the slipyoke swapped for a Jeep/GM, and then it went right into place on my MJ. I kept the flange from the D/S to 8.8", in case I ever needed it or found a person that wanted to swap in an 8.8". I say this because I will not use that overpriced, piepan thick diff covered, leaky spline mother. ever. Even in my V8 Ranger or BroncoII. Link to comment Share on other sites More sharing options...

My XJ lift settled in at just over 5 inches in the rear, I used a 97-98 ZJ front from a 4.0L.

mvusse Posted August 26, 2009 Share Posted August 26, 2009 If you go with an XJ front style driveshaft with the double cardan joint at the transfer case end, you will have to rotate the axle quite a bit. That type of drive shaft is designed to run with a 0 degree joint angle at the axle end. Rotating your rear axle that far would require a fill plug much higher up the diff cover than standard to be able to fill it to the correct level. You may be better off getting a shaft with a single joint on each end. Link to comment Share on other sites More sharing options...
