Not quite mobile yet, Lynn, but getting there.
So the inner tracta joint is all new, but just to let you know about the
outer tracta joint; the hard chrome plating of the hub shaft fork had some pits (due to fatigue spalling, I think), which had caused some galling on the mating tracta joint "ball" (jeez, the part names are complicated). But this damage had not been causing any running problems prior to the inner tracta joint seizing so I happily stoned off the high spots on the joint "ball" and reused the parts.
Now, knowing I have a money back guarantee makes me feel even more confident.
