Can you drive with hubs locked in?
If you leave the front hubs locked, the front wheels will drive the front axle when you are in 2 Wheel high. The differential is disconnected from the front axle when you aren’t in 4WD high or low. You will get somewhat less mileage and you will promote extra wear on some parts of the front drive system.

The hub is a component where the wheel is directly mounted to, and is outside the axle.

What are the benefits of manual locking hubs?
