Checking Front Toe Angle

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

Check that the instruments are calibrated to one another on the front and rear axle. This is extremely important in order to be able to adjust toe angle of the front wheels in relation to the car's thrust line (geometrical driving axis).

The thrust line is the line created when the toe-in angles for the rear wheels are equally divided (see the illustration). 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.
