Abstract: A suspension component assembly having a knuckle that attaches to the suspension system providing a generally vertical support from which a generally transverse cantilevered spindle may extend. The knuckle defines a tapered spindle-bore and the spindle has a tapered portion extending from a cantilever portion at least partially disposed within the tapered spindle-bore. The tapered portion of the knuckle disposed in the tapered spindle-bore provide a tapered joint which distributes the loads between the adjoining surfaces of the joint caused by the moment placed on the spindle by vehicle weight more effectively than a non-tapered spindle disposed in a non-tapered spindle-bore.
