Caster
Caster is the angle at which the swivel pin (king pin) deviates from the vertical when viewed from the side and is given in degrees.
When the swivel axis is inclined rearwards, as shown, caster is said to be positive (+); when inclined forwards, it is said to be negative (-). The
Saab 900 has positive caster.
Swivel Pin Inclination
Swivel pin inclination is the angle between the swivel axis (an imaginary line running through the centre of the ball bearing at the top of the
MacPherson strut and the centre of the ball joint on the suspension arm) and the vertical. It is given in degrees.
