kyleag89 Posted July 7, 2010 Share Posted July 7, 2010 Well I am installing a 95 AW4 and transfer case into my 89 MJ. My transfer case has vacuum lines running out of it.. How am I supposed to make the 95 T case work? Link to comment Share on other sites More sharing options...
Pete M Posted July 7, 2010 Share Posted July 7, 2010 both t-cases run without vacuum. :thumbsup: the vacuum in your old t-case was used to power the CAD in the front axle. You shift the t-case into 4wd, and the vacuum is switched and diverted to the CAD, which engages the funky 2-piece front axle shaft. If you still have a CAD front axle, you can just shim the CAD to be engaged all the time and then everything will work properly. :thumbsup: But make sure you plug the originating vacuum line where it comes out of the engine or you'll have a vacuum leak.

kyleag89 Posted July 7, 2010 Author Share Posted July 7, 2010 Ok I actually helped my father do that on his MJ. Does anyone have a link to a good write up on how to do shim the CAD? Found one.. http://comancheclub.com/forums/viewtopic.php?f=9&t=18415 Link to comment Share on other sites More sharing options...

kyleag89 Posted July 7, 2010 Author Share Posted July 7, 2010 What kind of gear oil do I use for the D30? Link to comment Share on other sites More sharing options...
Geonovast Posted July 7, 2010 Share Posted July 7, 2010 You should be able to lock the CAD without losing much, if any, oil. Link to comment Share on other sites More sharing options...
Pete M Posted July 7, 2010 Share Posted July 7, 2010 but if you do need some, I believe it's just plain ol' 75-90 weight. Link to comment Share on other sites More sharing options...
kyleag89 Posted July 7, 2010 Author Share Posted July 7, 2010 Thanks guys! I am hoping my swap goes successful... I took the driveshafts off last night and my U joints fell apart.. LOL strange because they didn't make any noise at all. I am just hoping I don't have to swap the TCU into my truck. Link to comment Share on other sites More sharing options...
