    Abstract: A tool and method for removing draw wedge bolt during replacement of the kingpin of a steering system assembly is disclosed. The tool is adapted to attach to the threaded end of a draw wedge bolt of a steering system assembly. After the tool is attached, sufficient force can be applied to the impact end of the tool using a manual or pneumatic hammer without damaging the draw wedge bolt. The tool also provides an adapter which allows the tool to affix to various sized draw wedge bolts from different vehicle manufacturers. The impact end of the tool is also keyed to be able to be turned by a wrench of a socket. This tool and method allow for faster and easier removal of the draw wedge bolts than previous methods.
