I think I'd do the same as you're thinking, run it and try again in 6 months or so...
The way it looks to me is that they insert the threaded tapered shaft into the machined "socket", set a "cover" in place that's got the zerk fitting hole in the center and swage the body closed to hold the cover. I'm thinking these got swaged really tight, so that there's just no room for the grease to flow through to the top. That's the only thing that makes sense to me, but it's damned tight tolerance! Hoping they wear in a bit with a few road miles, or I'll be contacting TCI or Pete & Jakes for a pair of new ones! Warranty is probably still good from '09, right?
