When you pull the 4by shifter there's a kind of loud clunk that scares you to death at first, but its just the transfer case shifting. I don't shift to 4hi in motion just because I want to baby the gears in the transfer case but it can be done while moving if you just yank it quickly into place. If it grinds (X never has, Path did all the time) just pull a little harder so the teeth will mesh.
