The driveline bind is caused by the difference in distances travelled by the front vs. the rear axle, while turning. In a turn, the front axle has to travel farther than the rear. I have found 2 ways to shift from 4wd to 2wd.
First way is when ready to shift out when leaving trails, stop, unlock the front hubs, then get back in, turn the sterring wheel to one side or the other, and back up. This will release the hub gears, which are spring loaded, when the bind is released. Then I have no problem shifting out of 4wd.
Second way is similar, but for times when you are not finished wheeling. Leave the hubs locked, turn the steering wheel, and reverse while maintaining gentle pressure on the t/case shifter. After just a little bit of movement (about 1 foot), it will release, and shift normally.
Normally, if you are running on a straight trail, the t/case should not be in any bind, and you should be able to shift at any time (with the front hubs locked).
