Operating the locking hubs manually only help if the automated ESOF system is failing to operate the locking hub. Also, IMO, it is not a bad idea to occasionally manually lock them to spin the components without having to drive in 4 wheel drive.

But, the front differential is a normal open differential ... it is not a "locker." So, you can lose traction and only have one tire spinning away up front.
