ABSTRACT:
A structure and method for adjusting alignment of steerable wheels movable supported by a ball joint with a ball joint stud having an annual tilt bearing surface carried thereon, the structure comprising a bore defined in a suspension member and configured to receive the ball joint stud therein, the bore being larger than the ball joint stud and including therein a concave bearing surface in the form of a truncated sphere, the ball joint annular tilt bearing having a convex surface shaped to fit the spherical portion of the bore bearing surface, and a wedge washer proportioned to fit adjacent a ball joint nut, alignment being obtained by placing the tilt bearing on the ball joint stud bearing movable in the concave portion of the bore bearing surface, and positioning a wedge washer on the proper angle in the proper orientation to incline the ball joint stud as required for proper alignment. Orientation is determined by the position and angle of the wedge washer. The concave and convex bearing surfaces may be defined in discrete components.
