I can't even read that whole post. Try using punctuation
The manual says you can shift into 4x4 "on the fly" but don't do it. The hubs engage and the driveline has to immediately catch up to the speed the tires are turning = bad. Stop completely before engaging 4x4. You can disengage while moving without trouble.
Better yet, buy AVM hubs. Engage the hubs when you are in bad weather, and you can shift in and out of 4x4 on the fly.
