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.

DETAILED DESCRIPTION The present invention relates to an apparatuus and method for onsite repair of motor vehicle, especially truck and tractor front axle steering eyes.
The apparatus includes a pair of generally mirror-image members coupled by linear bearings and locking devices which secure the mirror-image members to the upper and lower surfaces of a steering axle adjacent the eye.
A first drive assembly provides rotary power to a boring bar which extends through the eye and between the members and is supported for rotation thereby.
A second drive assemmbly rotates a pair of threaded lead screws which advance the boring bar axially through the eye.
A pair of quick connect and disconnect assemblies receive and release the threaded lead screws prior to commencement of and at the completion of the boring operation.
The mirror-image members accept pairs of an assortment of collars which adapt the apparatus to various sizes of eye diameters as well as receive various corresponding sizes of boring bars.
The method includes the steps of selecting appropriate pairs of collars and a suitably sized boring bar, positioning the mirror-image members on the upper and lower faces of the eye, centering and tightening the apparatus to the axle and making appropriate cutting passes, typically a first rough cut and a second finish cut through the cylindrical eye.
It will therefore be appreciated that an object of the present invention is to provide an apparatus for restoring damaged cylindrical surfaces.
It is a further object of the present invention to provide an apparatus for the onsite repair of cylindrical surfaces in motor vehicle steering axles.
It is a still further object of the present invention to provide a method for the repair of steering axle components.
It is a still further object of the present invention to provide a method for the onsite repair of cylindrical surfaces in motor vehicle steering axles.
Further objects and advantages of the present invention will become apparent by reference to the appended drawings and following description
