your best bet is to buy hubs, measure the balls, order the right balls
the ones I had were 13/32" so 0.4065"

I would try it if I had extra $100 laying around. But I don't

A little late to the topic, but I thought I'd add a data point for the DIY crowd:

I recently bought hubs/bearings through the local NAPA, and the ARP studs from 949. The holes in the rear hubs were too small (~.020") for the studs, and the holes in the front hubs were too big (by a lot). Both parts were for 90-93, I am aware that the 94+ uses a different stud in the rear... that was not the issue here.

I had to drill out the rears after pressing out the 'stock' studs and was able to press in the ARP studs. I returned the fronts, and will be sourcing a 'blueprinted' pair from one of the Miata shops with studs already installed.

Just a heads up that aftermarket replacement hubs may not be dimensionally accurate to the OEM parts. I guess the chinese figure if the stud is in the right place, and has the right thread, the spline dimensions don't matter...

Did you find any ARP studs with the same knurl dimensions as the ones you pressed out (the ones the chinese used)?
It might be a way to get both cheaper hubs and cheaper ARP studs. :)

Honestly, I already had the studs, so I didn't look very hard.... I took a call to ARP to find the required dimension for the hole, though. They suggested .502"... I didn't have a .502 drill bit, but I did have a 1/2"... It worked.

The rear hub holes were ~.480" on the Napa hubs. I didn't measure the front, but they were probably something like .540"...

Serviceable junkyard hub + G10 balls + Amsoil 2000 race grease = capitalist victory

When are you going to start selling G10 balls? I would much prefer to pay a bit extra from you to know I am getting the correct ball bearings over having to try to source them myself and possibly getting the wrong sized ones.

Patience, young grasshopper. Patience.

Knowing that they are in the works is all I need to know for now. I probably will not need them till sometime in the spring when I actually get that far into my Lemons car build.

Do you ------s want to see my balls?

Sav: y u no Amsoil dealer? I'm looking at buying some stuff from TSE sooner rather than later, and I would absolutely throw some MGT and a tube of 2000 grease onto the order. I'd rather support you than my local jackass Amsoil dealer. G10s would make it that much sweeter, I know I will need to do my hubs eventually.

I am an Amsoil dealer. Amsoil has some asinine advertising policies that don't allow me to post prices on my website, but I can reply to emails or PMs with price quotes. I prefer to automate my website as much as possible, so I end up just not putting the stuff on my website.

We typically have MTG tranny fluid, SVG diff fluid, Dominator 15w50 motor oil, and 2000 race grease in stock. PM/email me for price quotes.

Any pictures of bearing failures? I would love to see what fails...

To bring this back. I measured my prime choice auto hubs from ebay. The stupid cheap ones. Inside set of balls were exactly 13/32 or 10.32mm on my calipers, the outside set of balls were all 10.30mm or just under. Not sure if this is atypical and all balls should be the same size or not. Just one more piece of info.

Another unhappy ART customer here. My right front hub lasted approx. 26 20 minute sessions on 205 R888s.

Emailed him, he asked what tires and wheels I was using, now two more emails to him over the last 9 days has netted NO RESPONSE.

Needless to say, I'm incredibly pissed I paid $205 bucks for a hub with a "Limited Warranty" and the guy won't respond. 5 track days on R888s is not an acceptable life span for "blueprinted" hubs, IMHO.

Anyone else selling hubs that are worth a damn? I'm too lazy to repack my own.

Is ART even in business any more? I thought he closed down shop and moved to Europe.

Dont be too lazy to re-pack your own. After you've done it once or twice it only take 10-20 minutes a hub.

Yeah, you can still order them from Flyin' Miata as well. He responded to my first email, but has ignored the last two.

I'm not in a huge hurry, but lack of communication from vendors pisses me off to no end.

Money > Time

I've read that thread. It's hard for me to find time to work on the car as it is (and I hate doing it), so anything I can do to spend less time in the garage is a win for me.

As much as I can appreciate this*, I re-packed some eBay bearings with the Amsoil special sauce.



* I have probably spent as much or more in labor as I have in parts for my car because I finally got sick of seeing it up on jackstands surrounded by the boxes of parts I had been accumulating. So, I gathered up all those parts and dropped them off with the car at a quality local shop and said, "put all these things on that car and call me with the total due when it's ready to be picked up."

Since this got necro'ed.
I'm about to replace all my wheel bearings.
What grease should I use on hub shafts?

Front hubs are from Planetmiata.
Rear bearings are from parts store I know work for. Going to have them pressed in.

AMSOIL or Redline CV2 seems to be the consensus around here.

In fact, EO2k has a pic of the AMSOIL grease in his hub rebuild thread.

The local parts store had Redline in stock, so Redline was used on my shafts.
Smooth and slippery.

And red too.
