There was an ongoing discussion about doing this, but I was unaware anyone actually doing it. There was a vendor who was going to offer *****, but then we all decided repacking using correct grease or replacing a damaged hub with an aftermarket hub packed with correct grease AND proper brake ducting was easier/cheaper than fancy exotic *****.

I guess I don't understand the impetus for replacing the *****. Blindly replacing the ***** sounds like a solution looking for a problem. I'm not trying to be contrary or combative, I'm genuinely curious what problem you are trying to solve. Did you have a bunch of galling on the ***** and you were trying to salvage the hub?

Makes sense. I guess its not something I've looked into as I've not experienced this failure mode.
So how many noobs are we going to get measuring bearings for concentricity with plastic harbor freight calipers?

Exactly I mean, I own a nice Mitutoyo 0-1 .0001 grad +/-.0001 mic but its not something I would expect to find in the average Miata enthusiasts tool box.
Though I would imagine we have a rather larger percentage of users on this forum who DO own such things compared to most other Miata 'communities'

Jesus Sean, what did you do to those poor things?
Plus the $150+ tool needed for the level of accuracy required to make this worth while. Just sayin'
I personally think it comes down to duty cycle or use case. I'm not sure we need to send everyone out to buy a mic and bag o' ***** every time they repack a hub. The basic 3-4 times a year HPDE + autox or street driving guy can probably get away with a fresh hub, good grease and frequent inspection for quite some time. If you are planning on run a race series on the regular or you already own the tools then yeah, its probably worth the effort.
Of course, you could just go buy blueprinted hubs from FM @ $192/ea, sans studs https://www.flyinmiata.com/na-nb-blu...ront-hubs.html

I just made up the number above for the example. Assuming the hypothesis is on point, im not even sure what the diameter tolerance severity is.
I have a spare hub that needs disassembled and repacked. If I ever find the time, Ill see what my starrets say about all this. Hell, maybe I can start batching ***** for people, and I can sell them in a nice little sack.

Also the FM hubs are not guaranteed to be any better. Many people on here have had the same issues with those. I am pretty sure Hustler had issues with the hubs FM sells.

My local track, Hallett, is rough and we aren't shy about liberal use of the curbs.
They did warranty the hub which was nice.

I wasn't until I saw SADfab BALL SACK. Where's my safety pin ..
So its probably reflection / ect but I'm seeing what looks to be a bunch of little weld spots on each ball ..
As for buying these off ebay .. they're cheap enough to try but what's the chances that' they're as good as / better than OEM ? Maybe there's obvious answers in the listing, but I'm a noob without $150 of tools to QC.
Have you been able to go back out with the replacement hub ? Curious as to how that held up.
