I am new to off roading and I am looking to learn how and when to use things like the center locking diff, 4hi and 4 low ect. Are there any good videos or articles to read that you would recommend to learn the basics? I am worried that I might damage something if I engage things at the wrong time. If the videos happen to be GX specific that would be awesome but I figure all the systems are similar so anything will be better than nothing.
