An alignment device measures an angular offset between a vehicle body axis and a vehicle drive axis. The device includes an arm having a mounting portion for mounting to a vehicle such that the arm is aligned with the vehicle body axis. A wheel support member is coupled to the arm for rotation relative to the arm. A wheel is rotatably supported by the wheel support member and configured to roll on a ground surface, such that the wheel and the wheel support member are configured to self-align with the vehicle drive axis when the arm is mounted to the vehicle and the vehicle is driven on the ground surface. An indicator displays the angular offset between the wheel support member and the arm, which is indicative of the angular offset between the vehicle body axis and the vehicle drive axis. A method of carrying out a measurement with the device is also disclosed.
