Abstract: The present invention relates to a measurement system for measuring wheel angles and determining the position of chassis units on a vehicle. The measurement system includes a measuring unit which can be mounted on a vehicle and arranged to measure angles and distances in the horizontal plane with reference to the longitudinal axis of the vehicle, and in the vertical plane with reference to the vertical direction. The results of measurement are fed to a control unit, connected to the measuring unit by a lead. A computer which compiles and computes the measurement results, and provides information on the vehicle wheel alignment angles and the positions of vehicle chassis units by means of a display monitor or a printer connected to the control unit.
