Grinding and problems with 4wd

Iíve got a 1998 4.0 automatic Sahara and was off-roading yesterday in it. Everything was going fine until I tried to shift into 4lo. It shift in fine but then I went to try and climb an obstacle the transfer case shift handle kicked into neutral on its own. I figured it just slipped but then when I tried to put it back into 4hi it stated grinding and I couldnít shift out of neutral. I tried to put the Jeep in park and turn it off but that made it grind too so I turned it off and put it into 2hi then turned it back on and had 2wd. I tried putting it back into 4hi like I usually do at a slow roll and in drive but the lever wouldnít pull into gear. The only way I could get the t-case to shift was in neutral but when I put it in 4hi and started it back up the 4wd light was off and I had no power to the wheels. I tried to shift back into 2wd but it grinded bad and I couldnít without turning the Jeep back off. Is my t-case shot or is there something else going on?

Your tcase lever mechanism almost certainly has just pulled out of adjustment. There is but one bolt with a 1/2" head that holds it in adjustment, it can slip but it's easily put back into adjustment with nothing but a 1/2" wrench. Once you get it back into adjustment tighten the snot out of that bolt. You can probably see a mark on the rod the bolt holds to indicate where it used to be.

You can see the bolt circled in red here...

Hey Guys, if this is a typically common problem you might wanna try a allen head set screw. The face of these are shaped to apply an exponential amount of force to grab what its positioned against. These are the norm on machinery,pumps and electric motors and Ive rarely seen one come loose after thousands of high torque starts. Just a thought.

In reality, while it occasionally happens, it's not that common. In 23 years of TJ ownership it has never happened to me.

Sometimes that adjuster shaft gets mangled up from the PO and the adjustment block gets seized on the shaft. I had to remove mine with the adjuster and use a vice to get it straightened out. Apply some grease to it where the block resides so prevent this in the future.

Additionally, the plastic bushings fail over time and you need to rebuild the mechanism. While the stock linkage works fine if everything is in good working order, many people switch over to a cable shifter as an upgrade instead of rebuilding the linkage.
