On a 4 wheel drive capable Ford Ranger , the transfer case is bolted to the back of the transmission and allows power to be transferred to the front wheels
Transfer box is probably a misnomer for a transfer case ... a gearbox that delivers power to a second axle in addition to the axle that "normally" delivers the power to the wheels. In a typical four wheel vehicle, the transfer case delivers power to the front wheels in addition to the standard power delivery to the rear wheels, in the case of trucks or older SUVs. In a passenger car, the standard is front wheel drive, so a transfer case might be used to deliver power to the rear wheels. In either case, the vehicle is being reconfigured from two wheel drive to four wheel drive, by engaging ... or disengaging ... the transfer case. In all wheel drive vehicles, the transfer is happening all the time.

If your transfer case doesn't have a power divider lock, then the torque from the gear rotation will follow the path of least resistance - which, in this case, would be the front shaft, which will have significantly less resistance.

That depends on if there is a front axle disconnect. Your problem could be with a switch that tells the front axle to engauge.
