A gearbox assembly for an electric power assisted steering apparatus includes a gearbox housing, a worm shaft, a main bearing assembly, and a first fulcrum means. The worm shaft may be supported relative to the housing by a main bearing assembly at an end closest to the motor. The main bearing assembly may include an inner ring defining an inner bearing race, an outer ring defining an outer bearing race, and a plurality of bearings that run between the two races. The first fulcrum means may be located on a first side of the main bearing assembly which reacts only the axial component of the wormshaft tooth load for a first direction of gearwheel torque. A second fulcrum means may be located on a second, opposing, side of the main bearing assembly, which reacts only the axial component of the wormshaft tooth load for the second direction of gearwheel torque.
