Lets clarify, when does the clicking occur? just when your in 4 wheel drive or all the time? only on corners? left corners or right corners? Clicking on corners can be almost any steering component or a bad cv joint. Constant clicking on a corner would be a cv joint. If it clicks once, like a pop, its a steering component. Id recommend getting a front end check to properly diagnose the issue, its hard to the untrained eye to tell if its a pitman arm, tierod, or steering rack thats causing the issue. hell could be a loose bushing or a loose shifting part
