Checking Front Toe Angle

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2011 Volvo V50, 2010 Volvo V50, 2009 Volvo V50, 2008 Volvo V50, and 2007 Volvo V50. However, it is still accessible from the selected car via links, so may be relevant.

Check that the instruments are calibrated to each other on the front and rear axles. This is very important so that the front toe angle can be adjusted in relation to the thrust line of the car (geometric driving axis). The thrust line is the line formed when the rear wheel toe angles are divided equally, see 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.

NOTE: The differences in the diagram in, see Fig 1 are heavily exaggerated in order to illustrate the differences.

Check

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