Pump or gear box - without the tool to check the pump pressure it is a 50-50 chance, well not quite, it IS the pump about 7 of 10.
With the truck moving slow dial the steering wheel lock to lock 3-4 times and check the fluid level. If bleeding the air out does not help and the pressure hose is not leaking then it is the gear box.
