Abstract: An apparatus and method is directed to onsite repair of vehicle front axle steering components. The apparatus includes a pair of generally mirror-image members coupled by linear bearings and locking devices assembly provides rotary power to a boring bar which extends between the members and through the eye of the axle and a second drive assembly advances the boring bar axially along the eye. The mirror-image members accept pairs of an assortment of collars which adapt the apparatus to various sizes of eye diameters and corresponding boring bar sizes. The method includes the steps of selecting appropriate pairs of collars and a boring bar, positioning the members on the axle, tightening the apparatus to the axle and making appropriate cutting passes, typically a rough and finish cut, through the eye of the axle.

The apparatus includes a pair of generally mirror-image members coupled by linear bearings and locking device which secure them to the ends of the axle. A first drive assembly provides rotary power to a boring bar which extends between the members and through the eye of the axle and a second drive assembly advances the boring bar axially along the eye. The mirror-image members accept pairs of an assortment of collars which adapt the apparatus to various sizes of eye diameters and corresponding boring bar sizes.

Abstract: A method and apparatus for rebuilding vehicle axles permits rapid repair at the failure site. The method comprises the steps of removing the damaged terminal portion of the axle including threads and bearing surfaces, boring a concentric cylindrical cavity within the axle, cutting radially oriented passages in the axle wall which intersect the cavity, providing a replacement terminal axle portion, and inserting the terminal axle portion into the cavity and securing the replacement axle portion into the axle by weldments or other suitable means. The rebuilding apparatus includes a substantially conventional boring machine having specially configured mounting components which facilitate securement of the apparatus to various axle structures.
