Do you have autoomatic locking hubs on the front? If so, one of them probably needs replacing. This is a common occurance with automatic hubs and is the main reason why a lot of people which to manually locking hubs. If you hear the clicking sounds and it's not engaging, then it is a good indication that the transfer case is working, but your hubs are not locking correctly.
