No. There are essentially three valves in the system – the 4wd switch, the left hub, and the right hub. In order to have 4wd ALL three must be engaged. If you close any one or any two valves the differential will spin but you won’t get any power to the front wheels.

Should my hubs be in auto or lock?
When the transfer case is in two-wheel drive, the hubs should be released, allowing the wheels to turn freely when spun by hand. If the axle shaft turns when you spin the wheel, it means the hub has not disengaged. To check engagement, rotate the axle shaft backwards. This should lock the hub.
Is it safe to lock hubs in 4WD?
However, driving with part time 4WD engaged (if you have hubs – you have part time 4WD) on dry sections of pavement you will not only create unsafe driving due to understeer – you may also cause expensive repairs due to “drive line bind”. By the way, locking hubs do not create more traction.
