An alignment apparatus for accurately aligning a replacement spindle with a pre-existing axle shaft to facilitate repairing a damaged axle assembly. The alignment apparatus may comprise an axle clamp assembly and a spindle clamp assembly. The axle clamp assembly may be mountable to an axle shaft. The axle clamp assembly may be self-centering and self-aligning. Similarly, the spindle clamp assembly may be mountable to a spindle. The spindle clamp assembly may be self-centering and self-aligning. The axle clamp assembly may be fixable to the spindle clamp assembly. By fixing the axle clamp assembly to the spindle clamp assembly, a desired alignment between the axle shaft and the spindle may be achieved.
