A method for characterizing steering gear reversal clunk noise in a steering system having a rack and a pinion gear, and electric power steering assist via a steering assist motor, includes transmitting a steering input angle control signal to a rotary actuator to rotate a steering shaft to a fixed steering angle with assist active. A linear actuator applies an axial force at a constant rate along a longitudinal axis of the rack. Axial rack acceleration is measured after imparting the axial force. A control action is executed when peak amplitude of the axial acceleration value exceeds a calibrated threshold axial acceleration value indicative of the clunk noise. A system includes the rotary actuator and steering system, a linear actuator for providing a calibrated axial apply force along the rack axis, an accelerometer for measuring an axial acceleration value of the rack, and the controller noted above.
