A method for measuring a rotation condition based on a frequency analysis of a rotation of a suspension stop part is provided to measure a rotation state of a wheel indirectly without a rotation variable by using a MacPherson strut connection. A method for measuring a rotation condition based on a frequency analysis of a rotation of a suspension stop part includes the steps of: installing a wheel on a chassis(2) of a vehicle by an MacPherson strut; detecting an angle variable of a rotation element(3); generating an analog signal which represents an angle displacement according to a time; performing a frequency analysis of an analog displacement signal to acquire a spectrum having at least one frequency window based on the rotation medium variable; measuring at least one data; measuring at least one rotation state corresponding to the rotation medium variable employing or the rotation medium variable from the measured data. |
