YUP... A stilson/ Monkey wrench and a small jack on its handle. This will allow you to easily rotate the axle in either direction. CW Link to comment Share on other sites More sharing options...
dasbulliwagen Posted May 26, 2009 Share Posted May 26, 2009 Ive used wratchet straps before to pull it into place. It wasnt pretty though, but I got the job done. I did it on a WJ that needed a new front axle here at work, but same setup for the MJ. good luck! Link to comment Share on other sites More sharing options...

CW Don't use a cheap pot-metal one from Harbor Freight.......it will snap clean in half. Ask me how I know :oops: Jeff Link to comment Share on other sites More sharing options...
maddzz1 Posted May 26, 2009 Share Posted May 26, 2009 Is it that the holes won't line up? or is that metal u-shaped thing ( Ithink it is to set camber or caster angle) bending up and blocking the hole? Link to comment Share on other sites More sharing options...
MrSimon Posted May 26, 2009 Share Posted May 26, 2009 I've had good luck using a bottle jack wedged between the frame rail and the coil spring plates. Extending the jack will push the axle forward so you can get the arm in. If the axle is too far out, the jack won't help. Link to comment Share on other sites More sharing options...
whoopingbob5 Posted May 27, 2009 Author Share Posted May 27, 2009 well thanks for all of the help guys i finally got it to move forward enough with a BFB so I'm just hooking up brake lines. i do have one question though. on the new front axle there is something right next to the LCA mount there is a cylinder thing with something that lookis like a vacuum line and two lines hoses that stick out towdards the back. i can't post a pic of it but i really would like to know what it is.

GirsMJ86 Posted May 27, 2009 Share Posted May 27, 2009 Wouldn't happen to be a CAD axle would it... *click link in my signature, page 3, last post is my DIY fix for that :thumbsup: * ~Alex Link to comment Share on other sites More sharing options...
whoopingbob5 Posted May 27, 2009 Author Share Posted May 27, 2009 that is exactly what it is. now what does it do?? Link to comment Share on other sites More sharing options...
GirsMJ86 Posted May 27, 2009 Share Posted May 27, 2009 that is exactly what it is. now what does it do?? It is a central axle disconnect (aka CAD). Basically it was another step in disengaging 4wd with certain models of x-cases, can't remember which off the top of my head atm. If it is not hooked up, or if it fails like most do, my fix will make it so it is "engaged" at all times. Rather then being a three piece axle, it locks it into place so it is the equivalent of a two piece axle. Most the time when a swap like this is done, or even just to get rid of the problem of the CAD axle, these axles are avoided. Hate to be the bearer of bad-ish news. If the fix is done there is no worries, your 4wd is not truly engaged until you pull the lever. Your front wheels will spin freely so long as the x-case is not engaged. ~Alex Link to comment Share on other sites More sharing options...
Pete M Posted May 27, 2009 Share Posted May 27, 2009 What he said. :thumbsup: It was a mistake that 99% of 4wd MJs are plagued with. :( Link to comment Share on other sites More sharing options...
whoopingbob5 Posted May 27, 2009 Author Share Posted May 27, 2009 ok so i just need to do your fix and i won't even have to worry about it anymore?? Link to comment Share on other sites More sharing options...
Automan2164 Posted May 27, 2009 Share Posted May 27, 2009 Yep, just lock-er in permanently, and forget it. :thumbsup: Rob L. Link to comment Share on other sites More sharing options...
GirsMJ86 Posted May 27, 2009 Share Posted May 27, 2009 Yep, just lock-er in permanently, and forget it. :thumbsup: Rob L. Do this and like I have written in the writeup, make sure you cap off the vacuum stalks that are coming off the CAD cover. Just get it nice and cleaned up and get some vacuum line caps from your auto parts store and you're good-to-go. The reason ya want to do this is so that no water gets in there. ~Alex Link to comment Share on other sites More sharing options...
xj92 Posted May 31, 2009 Share Posted May 31, 2009 You could also just replace the passenger side axle shaft with one from a non-disco model. If you do this, careful when putting the new axle shaft in not to push out the seal in the pumpkin. Link to comment Share on other sites More sharing options...
MrSimon Posted June 1, 2009 Share Posted June 1, 2009 I literally spent five minutes tonight to take your guys advice and shim over my CAD. I un-bolted the motor, slid the collar over both sets of splines, pulled the c-clip, moved the collar over, re-placed c-clip, installed motor ..... yes, its that easy. You don't need any extra parts at all. I drove it around and don't feel any difference. 4WD works perfectly. One problem though - apparently capping the vacuum lines is a good idea .... I didn't and now my heat will only blow through the deforster and not anywhere else. Gonna have to fix that. Link to comment Share on other sites More sharing options...
Pete M Posted June 1, 2009 Share Posted June 1, 2009 See? It's just that easy. :D Try to trace them as far back as possible and cap the source. :thumbsup: Link to comment Share on other sites More sharing options...
