930-550 Wheel Hub Compatible with Select Ford / Mazda / Mercury Models

Brand new. They work awesome!

Ordered two of these for my 1991 Mazda Miata. I was hoping for the made in Taiwan versions, but I received two of the made in China versions instead. The parts look good though...cleanly machined with no burrs on the splines. I'll be installing them shortly.I'm installing ARP wheel studs and was nervous about which part number to order. Some of the threads on the Miata forums mentioned that all the replacement hubs are machined with the 94+ Miata knurl diameter. I pressed out the stock wheel studs on these Dorman hubs and measured the bore, which was ~0.550". Looks like these have the 94+ knurl diameter, since the studs that were in them had a knurl diameter of 0.570". Thus, I'm glad that I ordered the ARP PN 100-7720 which has the correct later-model knurl (0.579") for these, rather than the PN 100-7719 which has the 90-93 knurl (0.515"). The ARP 100-7719 studs are correct for the front hubs of my car though.Hope this helps someone!

Good fit and finish

Used with Timken 1932S seals, Timken 510003 bearings, Timken RET237 clips on my Mazda 2003 Protege for front end assembly replacement, went easily and much quieter now. Highly recommended. I put the hubs and bearings in the freezer prior to assembly and went in easily using a press kit once I ground down one of the plates to a smaller diameter that fit my Mazda's steering knuckles.

930-550 will fit miata but the hub lug bolts are not correct in diameter where they go through the hub. The 90-93 uses ARP 100-7719 and the diameter of the stud itself is to small telling me this hub is actually only for the 95 on application. Now, if you do not plan on changing out the STUDS then this doesn't matter. But. If you plan to put long studs for DE / Racing and also go to install your ARP studs for a 93. You will be unhappy like me

Considering the price these wheel hubs are great. You can pay a lot more, but you don't get much more. I like the flat surface. The fancy ones with holes and grooves don't give you anything you need, only if you like the looks. Drilled hubs can actually fail and crack between the holes. The holes make a weak spot on the hub. Really !

Purchased for a stock 1995 Miata. Quality of the hub looks quite good and I've run it a few times on the track with no problem (but not I am in no ways a fast/skilled driver and was not running on R-Comp tires).The axle nut/spindle nut though, does not fit. My guess is that the nut may fit a second generation Miata (99-04), but the diameter of the nut was too large for the '95 1.8 axles.This nut sizing error occurred on multiple occasions, both ordering the hub here, and on RockAuto when I needed to replace the other side. Dorman needs to address this issue, as the nut is not a part found easily in stores and increases the downtime during a repair.

2001 MB miata rear wheel bearing job. Pressed out the included hub's studs and pressed in ARP 100-7720 extended studs. The studs were tight. I recommend a ball joint separator and a pneumatic impact wrench for removal and install. Fitment was 100%. Parts appear good quality
