PB Blast the linkage and let it soak for a good while. Then try shifting it forward. If that doesnt work you can always use a pry bar on the linkage for more leverage. I've done that before and it slid right back into 2H. Also, change the transfer case fluid, you might be running low or have muddy water in there causing binding. Welcome to the Jeep World!
