MX317, thanks for correcting me. To make certain I did a quick Google search, and you are absolutely correct! Thankfully, I haven't finished mounting the tire yet.
This evening I fired up my zinc plating set up, so I can re-plate some of the hardware which got missed when I put the front end together last time. I'm even plating the ends of the axle, one end at a time. I could probably get a bigger bucket and do the whole thing at one time, but for me it's not necessary. The center of the axle is hidden in the hub, and I give it a light coat of grease when I assemble it anyway.
