ABSTRACT:
Procedure and apparatus for monitoring the lash and the toe-in of a vehicle steering system by comparing the angular position of the vehicle's steering wheel as the front wheel spindles pass through preselected reference positions during tuning maneuvers. For example, an angular position transducer at one front wheel determines the instant at which that wheel spindle crosses the reference position in one direction and gates the output of an angular position transducer of the steering wheel to a comparator which stores the signal corresponding to the instantaneous angular position of the steering wheel. When that wheel spindle next crosses the reference position in the opposite direction the instantaneous output of the steering wheel angular position transducer is again gated to the comparator which then compares the two signals and generates a proportional output signal which is transmitted to a display means which functions to display an improper lash condition warning when the comparator output signal achieves a preselected magnitude.
