My Jeep (which I just got) is a 1988 model. Most of what I have read states they have a vacuum operated front diff. However, my front axle has no wires or vacuum tubes going into it on the pass side where most are. Was there another option of not have vac op?

The only hose coming out is at the top of the pumpkin leading into the engine bay which I am pretty sure is just a vent.

Thanks in advance!

BTW, my Jeep has 2wd, 4wd part time, 4wd full time and 4 Lo if there is a difference in the models.

 

Dont believe 242s came with the disconnect axle only 231s did.

 

thanks for the quick response!

 

Correct.

Here's how to shift them.

Here's how the factory suggests you shift the transfer case and I've been doing this since these things were new and I worked at the dealership. Quoted from the owner's manual. The suggestions in ITALICS are mine.

"To engage, shift the transfer case lever from 2H to 4H while the vehicle is moving at any legal speed". I let off the gas, throw the lever, and then tap the gas and let off.

4L position: " To engage, slow the vehicle to 2-3 MPH , shift the transmission to Neutral, then shift the transfer lever to the right and pull firmly rearward to 4L".

To shift out of 4L, shift the transmission into neutral with the vehicle stopped, shift the transfer case lever to 2H, then to D if you have an automatic, or into first gear with a manual, and continue on.

Thanks again!

 

Sure. Make sure there's good fluid in it and the proper level, too.
