Your front axle disconnect may not be working.

There is no situation that cannot be improved with a small but well-placed explosive.

Probably starting with the simple things like vacuum line problems, visual inspection then go from there. On my 95, I found the lines were damaged under the battery tray. So, probably looking at this type of thing first, then start looking elsewhere after that. It is less likely the t-case, and more likely vacuum, or the shift fork mechanism in the front axle. A couple of links. Found 1990 cherokee dana 30 write up, should be the same as yours I would think.

My 91 would have problems with the vacuum connector at the axle in cold weather (snow/ice). The plug that goes into the axle housing has two rubber vacuum connectors that can get cold/frozen and leak vacuum. The cheap fix to fix the/a leak here is to put two very small hose clamps on these two vacuum lines.

You did not state whether your 4wd light is coming on, but when you get a vacuum leak in the system the fork and collar will not slide over enough to engage the axles nor trigger the 4wd light. Vacuum should slide the collar inside, which will depress a switch on the inside of the housing to trigger your 4wd light. You can also get a broken fork which will still slide with the collar and activate the 4wd light, but the collar will not enage the axles.

then it's probably a vacuum line. check them for cracks or breaks.

it would be the lines that run up from the axle and just follow them to the top?

If it's not a leak it's the axle shift motor. If the light doesn't come on even when it works, it's because of the stupid switch they used in that year. They never work.
