I consider the equipment needed at a bare minimum would be a dial indicator with some type of magnetic or clamp mount system, some indicator dye such as Prussian Blue or white lead, and an inch-pound torque wrench for checking pinion bearing preload. 30 or 40 years' experience setting up rear axle gears helps, but I don't know where you can buy that!
