A fixture and method for replacing brake spiders on heavy duty vehicle and truck axles includes fixture having an assembly with a flat reference surface and two internal bores just slightly larger than the respective inner and outer bearing surfaces on the axle having a damaged brake spider. The fixture also includes longitudinally adjustable rods or fingers. The method comprises the steps of determining a reference distance between a feature of the axle and the brake. The damaged spider is removed from the axle with, for example, an oxy-acetylene torch. Next, a replacement spider is temporarily attached to the rods or fingers which are adjusted to locate the replacement spider at the previously determined reference distance. The fixture and the spider are then placed on the axle. The spider is then tack welded to the axle, the fixture is removed and the spider is securely welded to the axle.
