Abstract: A system for enabling replacement of a properly aligned, full floating, tubular rear spindle on an existing truck and trailer axle for welding without machining. The improvement of this system uses a first alignment plate for positioning about and partially beyond the beveled cut edge of the truck trailer axle with a plurality of spaced outrigger assembly clamps and a plurality of hold down fixture clamps. It uses an improved rocket ship jig having a recessed inner plate for positioning over the plurality of axial spacer sleeves, at least one of said spacer sleeves including a brake bolt. The system (and related methods) enable better three-dimensional positioning and centering up of replacement parts before welding. New outriggers using studs and nuts enable tilt movements, both up-and-down and axial (in-and-out) movements before welding.

Abstract: A set of alignment plates is provided for adjusting the relative location of the two ends of a vehicle axle with respect to one another prior to the commencement of a welding repair thereon. A first alignment plate clamps to a first jig element and a second alignment plate affixes to an axle component at the opposed (hub) end, both alignment plates being sequentially numbered or lettered and rotatable until proper alignment is achieved.

Abstract: Method and apparatus are provided which locate and orient a replacement for a damaged axle end on the basis of an opposite, undamaged end, whereupon welding can be carried out to permanently affix the replacement.

Abstract: A method in which a jig is used to position a replacement for a removed end-adjacent portion of an axle. The replacement is then welded to the remainder of the axle. A replacement part, a jig, and a kit facilitating the repair method are provided.
