In part time four wheel drive sytems when you drive in two wheel drive mode the Front axles/drive shaft is disconnected from the transfer case but they are still connected to the front wheels. Hence when the front wheels turn, they also turn the front axles/drive shaft. This has a number of drawbacks, Energy/power/milage gets wasted by turning the front axles/drive shaft when not needed. Secondly it adds to wear and tear of the front axles/drive shaft even when the jeep is driven in two wheel drive mode.
The free wheeling hubs disconnect the front wheels from the front drive shaft/axles so the front wheels can turn freely without having to turn the front shaft/axles along with the wheel, thereby conserving power/milage/energy and decreasing the wear and tear on the front drive line.
