Its the vaccume to the fork thats on the axel. Unplug the vaccume line on the axel and when its running see if it has vaccume. If it does than dirt is plugging the plunger. It happened on a trail to me. Use a can of brake parts cleaner and a small toothpick to clean out the plunger. spray it out good and black goo will come out. Let it dry and rehook the line. If this doestn work check the 4 plug vaccume line on the transfer case and make sure its plugged in. follow all the vaccume lines to motor also and look for cracks. I put a hp head on mine so vaccume is a little lower than stock. I shift into 4wd and foll forward slowly and rev up motor a few times to make sure i have good vaccume. Seems to engage fine at about 1500 rpms but at idle it doesnt. Hope this helps.
