Abstract
A method to monitor alignment of wheels of a vehicle through analysis of a GPS signal includes monitoring the GPS signal, determining an actual trajectory of the vehicle based upon the GPS signal, monitoring a vehicle sensor indicating an expected change in vehicle heading, determining an expected trajectory of the vehicle based upon the vehicle sensor, and indicating misalignment of the wheels of the vehicle based upon a comparison of the trajectories.
