Jeep stuck in 4WD. Can someone help??

Is there a way to get it to shift more loosely? Even when it worked, I hated shifting it because it felt like something was going to snap!

Is this a pretty easy fix? Easy to get too? Do you know what the cost of the clip may be?

Thanks!

pentrating fluid my friend. it will help unstick the linkages, I have a dakota that the linkage is hard to move, with some pentrating fluid and working the transfercase through its gears it moves much more free now
