A gearbox assembly for an electric power assisted steering apparatus comprises a gearbox housing which houses a worm shaft and a gear wheel, the worm shaft being supported relative to the housing by a main bearing assembly at an end closest to the motor and by a tail bearing assembly at an end furthest from the motor. The main bearing assembly comprises an inner race and an outer race separated by bearing elements, the outer race being supported by a carrier that is supported by an axle that is in turn secured to gearbox housing, the axle defining a pivot axis for the worm shaft that is located on the side of the worm shaft closest to the wheel gear and extends in a direction orthogonal to the axis of the worm shaft and parallel to the axis of the wheel gear.
