Checking Front Toe Angle

Check that the instruments are adjusted in relation to each other on the front and rear axles. This is extremely important so that the front wheel toe-in can be adjusted in relation to the thrust line of the car (geometric driving axis). The thrust line is the line created when the toe-in angles for the rear wheels are equally divided. The difference between the symmetry line of the wheels and the thrust line is called the thrust angle. The thrust angle must not deviate by more than a maximum of 0° ± 0.25° from the symmetry line of the wheels.

Check: 

• the symmetry line of the wheels
• the thrust line
• the thrust angle.
