Mazda's front hubs are reboxed NTNs, available for ~$100 in a few places. You can occasionally find Timkens for ~$65, and those are reboxed NTNs as well, but the Timkens may or may not have the ABS ring in the correct place and availability is spotty. I have yet to experiment with anything cheaper than the $65 Timkens.

 

Resale discount. Perks of running a side automotive business. :-)

 

Rock Auto $21.79 + $15.43 ground shipping to my location. Seems like I almost never find Rock Auto to be the cheapest overall for anything. Big orders don't usually help either because most every individual part gets its own shipping charge shipped from different locations across the country.

 

Contradictory Bob is contradictory

 

I should have an answer for you in a couple of days, because I just ordered the same thing from Amazon.

 

That's dissapointing, The 8 I bought from amazon two weeks ago were all the Taiwan variety. I didn't know they were for the smaller studs. Not a huge deal as the smaller knurl ARP studs still don't break.

 

Any chance you have a part number for the NTN and/or the Timkens?

 

When this is all figured out, I'm going to make a thread with all the part numbers compiled that I have. Before I do that, I need to get some verification that the below is accurate for ARP wheel studs:

ARP 100-7719 89-93 all corners, front 94-05
ARP 100-7720 rear 94-05 (and where hubs have been replaced since -94)

 

Amazons $32.34 with free shipping is less than Rock Auto’s $37.22 including shipping. Napaonline shows them in stock for $48.59 at the Local Napa store. If I hadn’t ridden my bike to work today I would go see what version Napa had in stock at lunch.

 

Experience w/Raybestos? These are $57 on Amazon Prime:

 

Timken: 513152 nonABS, 513155 ABS

NTN: W0133-1834777 nonABS, W0133-1599959 ABS

 

Correct. 7719 is all fronts and 90-93 original rears (plus some Dorman hubs), 7720 is 94-05 rears or all OEM replacement rears.

 

I suspect it's probably a Chinese-made version of the NTN/Timken. The ABS ring is in the wrong place as well.

The Japanese-made NTNs have green wheel studs.

 

Ok I just went to the local Napa. Quite an adventure actually because of the I5 bridge collapse over the Skagit river and 70,000 cars worth of daily traffic being transferred to surface streets! The hub they had was Identical to the Taiwan version of the Dorman 930-550 hub I got from Amazon but packaged in a Napa box. It uses 1990-93 studs.

 

Bah... I ordered parts 2 weeks too early. I've got Taiwan dorman hubs and 94+ ARP studs sitting here not doing me any good. Guess I need to order 90-93 ARPs. Anyone need a set of 94+ rear studs? (1 set = enough for both rears)

 

I got the same damn thing: one of each.

Ha! I did something similar. Before I realized there was a difference, I ordered 4 sets of 100-7720 (94+ rears), not realizing there were different part numbers front and rear.

 

You guys that ordered studs from us, send em back and I'll swap.

 

You can also use the f-body ARP studs in place of the 90-93s. Somehow it's significantly cheaper for 5 f-body studs than it is for 4 Miata ones.

Part number is 100-7708.

 

haha, related but I did the same thing with my speed6 when I had it. took me some time to find the info I needed, but I too found out the f-body studs fit the hubs.

guess I should check my hubs I have in storage due to this thread.

 

I'm swapping the hubs for new OEM Mazda as the current ones have been on the car ever since it rolled out of the factory.

There are no visibile signs or anything, it would be nice to get them x-rayed, but who cares.

I am having the hubs sanded down very slighly (2/100th) so you can actually slip them in and out of the bearings by hand, without destroying the bearings. I had that done a while ago so I'm not replacing bearings this time.
