I had a #272 t-case in my 88 chrerokee and had to swap it out. For some reason I was stupid and didnt check the # on the t-case going in and it a 242. There is a foue prong connector on the old t-case that the other one doesnt have a plug for. It does have another type of sensor on it though. Is that sensor a big deal? What is it? Is it interchangable?

 

Never heard of a 272, take a picture and maybe we can tell you what it is.

 

sorry the 242 is in and 231 is the one i pulled. My fault looking at the wrong #'s

 

If your 88 came with a 231 it had vacuum lines that engaged the disco axle up front and the 242 won't have it. If you haven't already you will have to find a way to manually engage the 2 piece axle or replace it with a one piece shaft. The vacuum connector could be what you are looking at on the old case.

 

Im dont think it vacuum line im looking at. It looks like a electronic plug that circular. As far as the axle I have no clue what I could do about engaging it. I see no vac line

 

Now the question is how do i engauge that axle? Cant i do it without damaging the axle? If i do tha will it stay engauged at all times? Any pics on how to do it? Don really have the funds right now to get a axle out of a 97 or newer

 

This is what I did, but no pics. It is fairly simple. Pull the vacuum motor assembly, only 4 bolts. Then you can pull the snap ring and move the fork over and reattach the snap ring or take it apart and put a spacer in it. I put the spacer in it. I had a piece of brass tube that worked perfect. Copper tubing would be excellent.

 

Been told you can flip the fork as well but haven't tried it.

 

that plug is most likely an electronic speedo sensor rather than a cable sensor. most likely you got this 242 from a zj?
you could maybe just switch out the speedo setup from the 231, but possible the speedo gear shaft might be a different length.

as for the vac axle, you can always just cheap out and slide the collar across the split shaft and hold it in place with a gear clamp. i've done it for years and had only needed to reset it once. it can be done for less then 5 bux and no more than 15 minutes from start to finish to do the job.

 

If it is the speedo you can swap the electric to cable just make sure you swap the gear as well and it will work fine.

 

Thanks all of you so much. I will try it in the morning a let you all know.
