Abstract

A ball joint extractor comprising a C-shaped clamp having an elongated vertical component at its central extent and having two horizontal parallel legs, an upper leg and a lower leg, extending from the opposite ends thereof; a fixed jaw in a U-shaped configuration having parallel legs in a horizontal orientation and a curved coupling section therebetween, the coupling section secured at its interior end to the outboard end of the upper leg, the U-shaped jaw having a horizontal lower surface and an upper surface angling downwardly from its curved coupling section with the interior surface of the U-shaped jaw being chamfered whereby the upper surface of the U-shaped jaw has a smaller surface area on its upper surface than its lower surface with the coupling section being a curve having an axis parallel with the axis of the long leg of the U-shaped member; and a cylindrical member with a threaded central aperture and an exterior surface secured at one edge to the exterior surface of the lower leg of the C-shaped clamp with the axis of the cylindrical member being co-extensive with the axis of the U-shaped member and parallel with the axis of the long leg of the C-shaped member.
