An electromechanical servo steering system may include an electric servomotor that drives a worm shaft that meshes with a worm wheel arranged on a steering shaft. The worm wheel is operatively connected to an input shaft of a steering gear mechanism, and the worm shaft and the steering shaft are rotatably mounted in a common gear mechanism housing. The worm shaft has a free end that is remote from the motor and an end that is close to the motor. The end that is remote from the motor is mounted in a rolling bearing, and the end that is close to the motor has a rolling bearing that is received in an eccentric lever.
