Front Hub nut torque spec?


Hi All,
I am planning to change the front hubs on my 2000 Miata and was wondering what the actual spec for torquing the hub nut is?
It seems that everything I see on the web site says between 125 and 150 ft/lbs.
Thanks for the assistance

I believe 123 - 159 lb-ft is the range.  I use 140-150 to give some wiggle room on the accuracy of my torque wrench.  I do not peen the nut during the install.  Instead, torque the hub nuts, install the dust cap, drive the car a bit (100 miles).  Pop off the dust cap, re-torque, and then peen.

Torque spec is in the range cited above. I did mine to 130 ft-lbs.
That said, yes, you DO need to hammer/crimp that nut into the axle keyway. The shop manual makes that clear enough. Its made of soft metal. You can hammer it in easily.
This is a nut you do not want to have backing off. Your whole from wheel, hub, rotor, and all would fall off.
Nor would I consider over torqing to compensate for lack of hammer/crimp. You'll just squeeze your band new bearings too hard.

Mitchel (Ya, I know..) says 123-159 ft-lbs. I am inclined to go to the max spec, as it's harder to over-torque a hub than under-torque it. You shouldn't have a problem torquing it to spec and peening down the collar into the keyway the first time. That's how any car in a profesional shop will be done.

Wildo,
As I re-read your post, I see that you do end up hammering in your axle nut, and that your 150 ft-lbs is not quot;over torqued,quot; as I said above.  My apologies.
Cheers,

Hi Guys,
Thanks for the info.
I changed both this morning in about 1hr 20 minutes total, torqued to 150 ft/lbs.
I also installed my new Hawk HP+ pads and rotors while I had everything apart.
