4WD help

Hey all. So I installed a 4inch lift kit on my jeep. Before it my 4WD worked but now it isn't engaging. I put the TC drop bracket on and I don't know why it's not engaging. After reading some I saw that there is a bolt I can loosen and slide to fix the linkage underneath the jeep but I'm not sure. Anybody help?

You are correct, there is an adjustment that needs to be done to get everything working correctly again. The factory service manual says:

SHIFT LINKAGE ADJUSTMENT
(1) Shift transfer case into 4L position. (make sure your shifter is fully in the 4L position)
(2) Raise vehicle.
(3) Loosen lock bolt on adjusting trunnion (Fig.
87).
(4) Be sure linkage rod slides freely in trunnion.
Clean rod and apply spray lube if necessary.
(5) Verify that transfer case range lever is fully
engaged in 4L position. (you can do this under the vehicle at the transfer case)
(6) Tighten adjusting trunnion lock bolt.
(7) Lower vehicle

This is the adjusting trunnion:



Let me know if you have any questions!

If you're not afraid of spending a little extra $$$, do it right and go with the Novak cable shifter which replaces all of that. I just installed mine over the past few days:

i have the same issue with mine. ever since i put my lift on it wont shift to 4lo. ive tried adjusting the linkage but since the jeep looks to be from the north its a little rusted on. ive sprayed pb blaster on it every day for a week to see if that did anything but i had no luck getting it to budge. any ideas on where to get a new little metal bar link? ive looked in the junk yard and online but cant find one

The Novak Cable listed above ^ might work well for you. It'll replace that linkage. Other than that you can look to the dealer for that part or keep search junk yards. Good Luck!
