Unless you have a Detroit Locker , Front and Rear , you standard 4x4 is only 2 wheel drive .... even posi ONLY gives power to the none slipping tire
True but....My fleet of 4x4s has mostly ARB selectable air lockers..

Detroit lockers do lock..but are the most hateful traction aiding dif there is when on the open road in icy conditions..with limited slip difs a close second place.
ARB air lockers. Best of all worlds..open-dif traction for stable operation in icy conditions..lock 'em up when you need to climb out of something bad,
