When to put a truck in 4 wheel drive? "4X4 Hi(gh)" or just "4 Hi(gh)" is normal four-wheel drive for added traction. "4X4 Lo(w)" or "4 Lo(w)" is used when plowing or getting the truck unstuck. If you have automatic locking hubs, you may have push buttons to change into different 4-wheel drive options instead of the transfer case stick-shift. Is there such a thing as a 4WD truck?
