A magnetorheological (MR) vibration damper for damping axial and rotational vibrations of an automotive steering system may include a housing encasing MR fluid therein and a gear-like rotor and orifice plate disposed within the housing. The rotor and orifice plate, which may be affixed to the steering wheel shaft, includes a plurality of gear-like teeth on its surface and a plurality of holes for producing shear and normal forces, respectively, on the MR fluid. Electric coils may be disposed within the housing for generating an electric field for activating the MR fluid. The MR vibration damper may be activated or deactivated by a controller by comparing a signal value from a steering wheel vibration sensor to a predetermined threshold value. The controller may be programmable by a user to increase or decrease the predetermined threshold value, so as to enable customization of driving feel.
