Also, at risk of preaching to the choir and I just skimmed the hubs discussion, but if there is supposed to be a cv stub through it, a used stub axle can be machined to remove the cup, leaving a bolt with sealing surface to hold it together. A tool to hold the hub by the bolt circle can be used to loosen and tighten the stub bolt. I made one from 3/8" steel plate and drilled to accept two wheel studs. Didn't need to countersink the plate. The stub cup (extremely hard material) can be rough ground off with an angle grinder, then spun while holding the grinder with light contact to be more precise for balance purposes.
