A steering axle stop for an axle steering joint assembly is defined by a stub shaft rigidly supported within a steering knuckle boss. In a preferred form, the stub shaft contains a plurality of apertures which extend through the shaft and perpendicularly to the longitudinal axis of the shaft. The steering knuckle boss is pivotal relative to the axle housing, and the stub shaft extends through an aperture of the boss which has its axis extending tangentially to the swing movement of the boss. The stub shaft is rigidly secured in any one of the selectable apertures by means of a clevis pin which extends through the boss perpendicularly to the latter swing movement. Also in a preferred form, the axle housing contains a projection which includes a contact surface disposed for limiting the rotation of the steering knuckle via contact of one end of the stub shaft with the latter surface. In a preferred form, the contact surface is concave and is geometrically shaped to accomodate abutting contact with one end of the stub shaft upon pivotal movement of the boss regardless of aperture selection.
