89 cherokee 4wd engage/disengage problem
 

okay I am stuck. I have been told that there is supposed to be a vacuum
line running to the front axle differential to engage the front axle to
4wd. I am as green as they come when it comes to this vehicle. I cannot
find a vacuum line running to the unit. If there is a vacuum line running
to it, where does it originate from; maybe I could track it back that way,

You may not have a vacuum disconnect on your axle. Mine doesnt. If there is
no box on the axle tube with lines two lines going to it then you are lucky
and have a non vacuum disconnect front axle.

If its not shifting, start with the simplest things, check your tire
pressure and make sure they are the same left and right sides, it is very
common for the shift linkage to slip a bit and need adjusting. the shift
linkage adjusts right underneath the jeep where the handle pulls on a rod
that connects to your transfer case.

An 89 is supposed to be a vacuum style axle lock. The vacuum switch is
on the passenger side of the axle tube on the back side.

Are you having an issue shifting into 4x4?

Mike, not all 89's have a vacuum axle disconnect. My 88 is a non disconnect.

Hey Mike, how have you been, are you any better? I havent been around here
in a while.
