Caster Description




Caster Description





Caster (1) is the inclination (tilt) of the king pin (2) or the steering axis either forward or backward from the vertical line (3).

Incorrect caster may result from one of the following conditions:

* Sagging springs
* A bent axle
* A twisted axle
* Uneven tightening of the spring U-bolt nuts

Tighten all of the U-bolt nuts equally. Refer to Fastener Tightening Specifications Front Suspension in Front Suspension. The caster will be unequal for the right and left sides if the axle is twisted.
