Kingpin Inclination

Kingpin inclination is a function of the steering knuckle design and cannot be adjusted. Caster, the alignment angle which provides the self-centering steering effect, is only adjustable on truck models which do not use strut-type front suspensions. If caster or kingpin angle are not within specifications on models with strut-type front suspension, check suspension components and sheet metal for damage, distortion and excessive wear, and repair as needed.
