    Patent number: 6286821
    Abstract: A method of making stabilizer bar pivot bushings (10). At least one length of a substantially plastic material (26, 28) that in transverse cross section has a shape that is arcuate about a central axis passes lengthwise through an extrusion die where an annular elastomeric body (22) is extruded onto the plastic. Then the body is transversely cut, including cutting through the plastic, at locations along the length of the extrusion, thereby creating individual bushings in which the plastic forms at least one shear plate.
