4 Low not engaging

I use my Jeep almost everyday for work and am frequently in 4 low during muddy or steep terrain. I haven't had any issues with my high or low gears yet but the other week I couldn't get the lever to fully "notch" into the low gear. 4 hi is fine and continues to work well. So right now it'll kind of half way sits in gear but when I let the clutch and give it some gas the lever will pop out of Low. I'm pretty sure my gears are good so I figure my linkage may be hung up or something. Any advise or similar problems from any of you guys? I have an 01' Sport 4.0. 163,xxx on the odom. No lifts, suspension or body.

Your transfer case linkage is damaged or worn. I would suggest installing a novak cable shifter or repairing the stock linkage components.

I can manage to turn a wrench to a degree. Would you say replacing that linkage requires just some basic mechanical skills or does that involve more skilled hands? Thanks for the help!

The mechanical transfer case linkage can slip out of adjustment which can be fixed with nothing more than a 1/2" wrench. There is a shift rod for the t-case that is held in a bracket by a bolt with a 1/2" head. That bolt can loosen & let the rod slip a little out of adjustment which can prevent it from pulling the t-case fully into 4Lo. You'll need to get underneath but it's a fairly easy and common task to perform.

I can post a photo of the linkage with that bolt circled but it's really easy to spot once you get underneath & look at the t-case linkage. Having someone work the linkage while you watch will quickly let you see how simple it is and where to make that minor adjustment to pull the rod back into the bracket that holds it. When you're done & it is working, tighten the snot out of that bolt so it won't slip out of adjustment again.

Thanks Jerry. Hopefully I can handle that, sounds pretty straight forward.

Did that today and still won't adjust enough even after putting in the tera flex adapter on the transfer case to correct the geometry from a 4" lift. It is a piss poor design with too many variables to be reliable IMO. I am going to order the Novak cable shifter and be done with that mess. Anybody install one and how do you like it?
