Duner Posted January 15, 2007 Share Posted January 15, 2007 Just completed the Rusty's 6" fully adjustable front setup on the 4wd conversion. Earlier skyjacker setup that I found at Pick a Part couldn't handle the 6" lift. Anyway now that I can get the driveshaft in I need to know how the vacuum lines tie into the vacuum source - its been to long since I salvaged all of the lines out of an xj at the junkyard. The transfercase and axle hookups were no problem where do they go after that? Link to comment Share on other sites More sharing options...
Pete M Posted January 15, 2007 Share Posted January 15, 2007 The page from the shop manual is the best I can do. I just throw away those stupid vacuum lines so I don't have a clue what goes where. Link to comment Share on other sites More sharing options...
GirsMJ86 Posted January 15, 2007 Share Posted January 15, 2007 don't bother with the vac lines. just do the CAD "fix" so it does not use vac to engage. there is a write up in my project section. http://www.comancheclub.com/forums/view ... c&start=30 Alex Link to comment Share on other sites More sharing options...
Duner Posted January 15, 2007 Author Share Posted January 15, 2007 Thanks for the CAD tip. I was going to do the cable thing eventually. What is the long term effect of having it locked in 4wd? gas mileage? wear and tear? Link to comment Share on other sites More sharing options...
87manche Posted January 15, 2007 Share Posted January 15, 2007 makes it just like the new ones. I replaced my disco axle with a non-disco, and it didn't seem to make a difference, can't even tell. Link to comment Share on other sites More sharing options...
Pete M Posted January 15, 2007 Share Posted January 15, 2007 You won't be in 4wd, you just will simply have the front axle shaft locked together so it can't fail to engage when you need it most. Jeep did the CAD thing for the theoretical gas mileage saved, but in reality there's no measurable difference. Heck, the Liberty that I borrow (for towing my MJ) saw no difference between 2wd and Awd on the roads. Link to comment Share on other sites More sharing options...
87manche Posted January 15, 2007 Share Posted January 15, 2007 the only other thing that was good abot the CAD was IF you hosed your frton DS or somethig in the pumpkin you could disengage it. Link to comment Share on other sites More sharing options...
GirsMJ86 Posted January 15, 2007 Share Posted January 15, 2007 yea down the road i am going to swap to a non-disco axle. that is the best thing to do, or just swap that side of the axle shaft. but if you swap to a non-disco axle you can go for a newer upgrade in the process and get bigger and better u-joints. but i have had no problems with the CAD fix or any change in mileage or anything.

Duner Posted January 17, 2007 Author Share Posted January 17, 2007 Thanks for all the help. I made the CAD conversion Monday it works like a champ and only took 15 minutes might have been ten but the c-clip deformed and it took a couple of minutes to find one the correct size. I'll post some pics of the lift as soon as the ice storm in Houston gives up, but it is comforting to know that my 4wd is available now if I need it.

mjeff87 Posted January 17, 2007 Share Posted January 17, 2007 I did the mod to mine back when I converted it, but I used washers to shim the fork over and left the c-clips in their original positions. It works great but was a pain to keep taking it back apart and adding/sutracting washers until I came up with the correct amount of them. More recently, when I helped Chuck get his new YJ on the road, I modded his CAD like you did, just by moving that one little clip....took about 2 minutes :cheers: Both times I didn't have my camera, and wanted to take pics. You're writeup is great, and I'm glad you did it. It's kinda difficult to describe exactly what you need to do in words, while a couple pics tell the whole story quite easily.
