Pete M Posted September 11, 2009 Share Posted September 11, 2009 ok i did my CAD fix today and took pics along the way. so here they are in order. located the CAD on the passengers side of the front axle. took the cover off and disconnected everything from the cover. slid the sleeve over to the left to "engage" 4wd. cover right after coming off. lost some oil but not alot. cover/fork side shot. top of cover after being cleaned. notice where the fork is, thats where it is when it is not in 4wd and first came off. the c-clip down in there on the rod against the fork needs to be pulled off to allow the fork to be worked over to the side it is in now as seen in the next pic. worked the fork over after takin the c-clip off. this side it will hold the sleeve in the 4wd position. just work the fork over (it is sort of hard but trust me it will go) then reaplly the c-clip to hold it there. didnt get any more pics but all you have to do now is bolt the cover back up and reattach everything to the cover. but leave the vac lines off. i just zip tied mine up for now til i get to the store and get some caps. i then put the truck up on four jack stands and tested it. i shot a video. here is the link to it. it is 5MBs so dial up beware. all it shows is the side of the truck with the tires spinning. Alex Basically, the old CAD systems had two points for engaging 4wd. Both have to be engaged for 4wd to work. Locking over the CAD will not cause you to be in 4wd all the time.

akamcbird Posted November 18, 2009 Share Posted November 18, 2009 is the front drive shaft balanced from the factory? will you feel it if not? Link to comment Share on other sites More sharing options...
Pete M Posted November 18, 2009 Author Share Posted November 18, 2009 is the front drive shaft balanced from the factory? will you feel it if not? yes, it is balanced. the 4wheel drive system is rated use at speed (on slippery surfaces). But if your U-joints are shot, they may cause some vibration. Link to comment Share on other sites More sharing options...

Pete M Posted November 21, 2009 Author Share Posted November 21, 2009 are the worth it? not worth it at all. Unless for some reason you wanted 2wd LOW. Link to comment Share on other sites More sharing options...
one_bad_MJ Posted February 2, 2010 Share Posted February 2, 2010 nevermind found one $219. its called posi lock on http://www.jeepforum.com there is a DIY write up on it you use a choke cable and a set screw to make it works good when your vac liines freeze up in the winter. plus when i had my xj i slid my collar over and re installed the vac ting and it was locked in all the time i got crappy fuel mileage your best bet is to cldean the vac lines good and use a zip tie and use it as is or build a 20.00 posi lock. http://www.4x4posi-lok.com/ http://www.4x4posi-lok.com/app_jeep.html diy threads http://www.naxja.org/forum/archive/inde ... 84798.html http://www.jeepforum.com/forum/f11/home ... ost4800595 Link to comment Share on other sites More sharing options...
wannabeMJ Posted May 26, 2010 Share Posted May 26, 2010 had a question on this I want to do the same thing on my truck but I'm wondering what to do with the vacuum lines after?? cut them or what?? Link to comment Share on other sites More sharing options...
Pete M Posted May 26, 2010 Author Share Posted May 26, 2010 leave 'em or yank 'em, that's your call. just be sure to plug any exposed ends so that you don't have a vacuum leak. :thumbsup: Link to comment Share on other sites More sharing options...
shawn Posted May 30, 2010 Share Posted May 30, 2010 "plus when i had my xj i slid my collar over and re installed the vac ting and it was locked in all the time i got crappy fuel mileage " i've heard doing this didnt really decrease fuel mileage in any noticable way. thanks for the sticky - I'm motivated now.

Pete M Posted May 31, 2010 Author Share Posted May 31, 2010 It should not affect fuel economy in any noticeable way. Unless maybe there was something wrong in the jeep. I mean, how much gas does it really take to spin the front driveshaft around compared to moving the truck down the road? :dunno: Link to comment Share on other sites More sharing options...
sinkrun Posted June 10, 2010 Share Posted June 10, 2010 Anyone know if this will work on a 1/2 ton 91 dodge tk? Dad just called his is so rusted it was almost gone so is the truck for that matter need a cheap fix. I am going down to take a look at it in the morning to compare it to the pics.

shawn Posted November 4, 2010 Share Posted November 4, 2010 ok , it didnt stay put. i went to go up a hill today and was surprised to find i was still in 2wd. -- so i went home and re-did it, but this time i held the fork over with a wide hose clamp. - i think this will keep it in place much more permanently.

shawn Posted November 17, 2010 Share Posted November 17, 2010 are the worth it? not worth it at all. Unless for some reason you wanted 2wd LOW. wouldnt another reason be (neighbour gave me this idea) to have the front diff welded and then use th cable actuator as a "locker" ?

Pete M Posted November 18, 2010 Author Share Posted November 18, 2010 why go through all that effort when a lunchbox locker is like only 200 bucks? besides, spool + 260 U-joints = trouble Link to comment Share on other sites More sharing options...
shawn Posted November 24, 2010 Share Posted November 24, 2010 not to keep messing up this post, but when i went to shift into 4 today there was no 4 ( just like before when the collar slid back over). took the cad cover off and the fork was broken ! i don't know if the clamp i put on had anything to do with that or not. in reading the tec section i see that its mentioned that simply putting the vac on upside down will keep the collar over to the engaged side. http://www.comancheclub.com/forums/view ... le#p259522 Link to comment Share on other sites More sharing options...
