A transfer control method for a full time four-wheel drive vehicle is provided to improve durability and marketability of the vehicle by preventing distribution of driving force of front and rear wheels when rotation speeds of each wheel are different from each other. A transfer control method for a full time four-wheel drive vehicle comprises the steps of: detecting a rotation speed of each wheel by a speed sensor(S10), determining operation of a transfer(S20) by comparing the rotation speeds of the wheels with each other by a controller connected to the speed sensor, operating the transfer(S30) by controlling the transfer by the controller and distributing driving force of front and rear wheels when the rotation speeds of the wheels are different from each other in the step S30, determining error operation of the transfer(S40) by comparing the rotation speeds of the wheels during a predetermined time by the controller, and stopping operation of the transfer and simultaneously operating an indicating unit provided in a metering board when the difference between the rotation speeds of the wheels is kept constant for the predetermined time(S50).
