Check 

IMPORTANT The level values are displayed by the electronic inclinometer in decimal degrees [°].

  1. Obtain the caster value from the form taking into account the front axle (FA) level values and rear axle (RA) level values measured previously.
  2. Check accident vehicles and vehicles possibly damaged in an accident.

    If necessary, check for unacceptable deformation on the body.

    IMPORTANT The caster on the front axle (FA) is not adjustable. Any greater deviations of the caster on the front axle (FA) may be down to the following reasons: Excessively large difference in vehicle level between left and right side of vehicle, deformation of lower control arm, deformation of front axle carrier, e.g. through accident damage, deformation of body, e.g. through accident damage.
