1. A method of repairing a damaged motor vehicle axle comprising the steps of:
assembling boring equipment having a boring axis to the vehicle axle;
disposing a mounting assembly on the vehicle axle, wherein the mounting assembly comprises:
a first portion and a second portion identical to and spaced apart from the first portion, each of the first and second portions having a substantially rectangular shape with centrally-disposed radiused opening disposed along an edge, the radiused openings of the first and second portions facing one another, wherein the first portion is connected to the second portion with threaded fasteners engaged with one or more threaded openings formed in the first and second portions;
a jaw disposed about an inner circumference of the radiused openings of each of the first and second portions, the jaws having an inner radiused surface shaped to contact and secure the vehicle axle within the mounting assembly;

aligning the boring axis of the boring equipment with an axis of the vehicle axle;
boring the vehicle axle to a desired inside diameter;
providing a replacement spindle assembly having an oil seal surface, an inner bearing surface, an outer bearing surface and a threaded terminal portion; the replacement spindle assembly having a region defining an outside diameter greater than the bored inside diameter of the vehicle axle;
heating the vehicle axle to enlarge the vehicle axle to receive the region of the replacement spindle assembly in an interference fit manner;
inserting the replacement spindle assembly into the bored vehicle axle;
grinding or cutting at least one opening in the vehicle axle at approximately 10 o'clock and 2′clock positions or approximately 60° off of vertical, and installing a plug weld in the at least one opening which engages the replacement spindle assembly; and
providing a circumferential weld between the replacement spindle assembly and an end of the vehicle axle.
