BEWARE THE WINDING!
Transfer cases used in permanently four-wheel-driven 4WDs (like a Toyota Prado and a Ford Everest) are designed to synchronise the difference between the rotation of the front and rear wheels (the same way a differential operates on an axle, really).
On a tarred or hard surface, if a transfer case does not synchronise the difference between the two axles (if you select 4H for a 50/50 split between the axles, for example) the result will be driveline wind-up.
This wind-up occurs when the mechanical components of a vehicle’s driveline bind or wear, creating a resistance in the system. That’s the bind or wear you get when you drive a part-time 4×4 in 4H on a tar road, and try to make a tight turn. There is a feeling of resistance, almost like the wheels won’t turn and are being braked by some invisible force. This is driveline wind-up.
Besides being annoying, it also has a detrimental effect on the mechanical components.
