An aligner or wheel aligner is defined as an instrument for measuring characteristic alignment angles
of a vehicle (see the "Characteristic angles" section).
A wheel aligner consists of a central unit and four measuring sensors for application to the wheels of
the vehicle.
1) ROC (Run Out Compensation). Off-centre and plane error compensation.
ROC renders the angle measurements independent of geometrical errors in the rim and/or wheel
mounting.
This procedure should be performed on all wheels.
2) Toe.
Angle formed by the equatorial plane of the wheel and the axis of symmetry or thrust axis of the
vehicle (Figs.7 and 8).
The axis of symmetry of the vehicle is the imaginary line which divides the vehicle in half lengthways,
while the thrust axis is the travel direction established by the rear axle.
The units of measurement of toe are the degree and the millimetre.
3) Camber or Inclination.
The angle formed by the equatorial plane of the wheel and the vertical plane (Fig. 9): camber is posi-
tive when the top of the wheel tilts outward.
The unit of measurement for camber values is degrees.

4) Caster.

The angle formed between the vertical and the projection of the steering axis onto the longitudinal
plane of the vehicle (Fig. 10).
Caster is measured with the wheels turned through 10° or 20°.
The unit of measurement is the degree.
5) King pin angle.
The angle formed between the vertical and the projection of the steering axis onto the transverse
plane of the vehicle (Fig. 11).
King pin angle is measured by locking the steering to 10° or 20°.
The unit of measurement is the degree.
