yjswampthing Well don't get too disheartenend. I was out muddin this weekend and thought something was weird. Sure enough, got it up on jack stands and my stupid disco isn't working. (You can tell if you put it in four and have a buddy or even yourself look under the car to see if the front driveshaft is spinning. When its off the ground, of course) Anyways I'm eventually gonna get solid shafts up there (tj style) but I think I"m gonna look into the cable shifter for now.

If the vacuum disconnect isn't working, neither wheel will get power in your case.

3jeepguy the easiest way is to engage 4x4 mode and crawl under it with the tranny in nuetral and try to twist the front driveshaft if it moves than the front axel is not engaging

3jeepguy if you have a locker in the front than just the passenger side won't pull but if your front is open than you won't have any front wheel action

jj33002 So if my vaccum isnt working does that mean that neither one of my front tires will pull in 4x4 or does it mean that just the passenger side wont work?

Here are some answers to your questions.

1. Yes in a since it is stronger than the 35 rear. There's no C-Clip axles. The main difference is that the front axle sees considerably less force (Like 50% less) than the rear axle does. All of the forces are generally pushing on the rear. So you can get away with running more tire on the D30 without Ujoint and shaft failure. (Note, that doesn't mean you couldn't break it before you broke your 35. Everything can and will break.)

2. Yes, they do sell or can be easily made plates to seal up the disconnect and you can run TJ shafts in it.

3. Yeah, buy the Warn small hub (5x4.5) kit for like 900 bones and bingo you have locking hubs.

NY94YJ Agreed.

I heard of people booty fabing it with things like peices of Garden Hose to keep the collar permanently engaged, this will work but will wear parts premature.

Damn, it's been awhile since I put one of those on a YJ, but I would bet you can find them cheaper elsewhere.

If you need one give these guys a call here in Phoenix, I am sure they can do better than 200.

A little steep for essentially a brake cable from a 12speed bicycle, but it will work. There are write up on how to make Do-it-yourself posi-loc's with just that....12speed brake cable.

4Jeepn Check the vacum lines at the connections. Also there is a kit they sell that removes the vacum and give you a solid axle shaft vs the 2 pc one.
05-03-2006 10:46 PM
jj33002 So if I find out that it is not working properly, what would be the first thing I could check, so that I could get it working again?

That is the exact way you can tell if it's not working properly.

1BLKJP That is called a Vaccum Disconnect. It has vacuum lines going to both the engine and the TCase. When you you put the Tcase in 4wd the vacuum created moves that shift fork over and engages the passenger side axle shaft.

This was not the brightest thing that Jeep had done with the YJ/XJ Dana 30 axles back in the 80's and early 90's. The vacuum lines can become brittle and break and then you lose it's function. A lot of guys go to a manual cable disconnect called a Posi-Lok.

Front axle question

On the passenger side it has that little box where the axle is split, it has that fork with the little "gear coupling" or whatever it is inside there. I was wandering how that worked. Does it engage the passenger side wheel when you put it in 4x or what? If you can tell I know nothing about how it is supposed to work so all the info I can get will help.
