Re: 4lo-- 2hi-- 4hi- Questions
If you've been driving with your transcer case shifter in neutral, then you haven't been going very far unless you've been rolling downhill. In otherwords if your tcase is in neutral your tranny might as well be in neutral. So you've either been in 2Hi or 4Hi. You would use 2Hi on all roads. Only your rear tires are turning under power then. In 4Hi all tires are turning IF your hubs are locked. If you unlock your hubs then you are turning your front driveshaft but the power isn't being put to your tires.
So to answer your question directly, keep the shifter in 2Hi and your hubs onlocked when on pavement.
