Hi all,

I'm new to 4WD ownership, and I heard it's a good idea to engage the center diff and 4Lo periodically to make sure they continue to function properly in the long run. Now my question is how often should this be done? Also, my GX is mainly a suburbia crawler and there's really no loose terrain near me. Is it possible to safely exercise the center diff and 4Lo on dry pavement?
