Abstract: An improved steering assembly incorporates an adjustably mounted lower boss in a steering knuckle. The lower boss can be positioned at any of a variety of locations relative to a rotational axis of the wheel mounted on the knuckle. This allows adjustment of the distance between an I-beam spring pad and the rotational axis for the wheel hub. In this way, the present invention eliminates the necessity to have a number of different I-beam configurations. Preferably, the lower boss is bolted to a flange on the steering knuckle. Further, the upper boss may also be removably mounted to the steering knuckle such that the distance between a steering arm connection and the spring pad may also be adjusted.
