Broke a lug nut stud today - a few questions

All this TLC I've been giving my new Tacoma back-fired today. I've worked on vehicles for thirty years, only because I needed to. I work now on my new Tacoma only because I want to.

Nonetheless, today I broke a lug nut stud during the routine 5k tire rotation. I use a Craftsman torque wrench set to 100 ft/lbs instead of the recommended 85 ft/lbs. (because that's the way I've always done it)

I use anti-seize on the threads instead of following advice to avoid it. (because that's the way I've always done it)

It is the driver's side front hub that has the broken stud. And I think I felt a second stud yield slightly when I was torquing the remaining lug nuts. And to make things even worse, I have the '15 TRD Off-Road wheels that use the less than common spline-drive lug nuts.

So my questions for TW include;

1. Is this a level one emergency? Have it towed to the nearest dealer and get ready to bend over?

2. As far as repair, should I consider replacing all 24 lug nut studs (6 x 4 wheels), or simply the broken one?

Any other advice or insults would certainly be appreciated.

Thank you

 

Not level one like level 5. Just replace the broken stud unless you plan on running some big ass monster truck tires

 

Well that is good news. Thanks. I think I'll just repair it myself.

Anyone know the correct replacement wheel stud for the front wheel of a '15? Should I consider longer studs now that I'm running the TRD Off-Road wheels?

 

There's no need to use anti-seize with close-ended lugnuts. However, if you insist, you are supposed to reduce the torque applied when using anti-seize by about half. i.e. if the manual calls for 83 ft-lb dry torque, apply only ~41 ft-lb if using anti-seize. Conversely, what you did (100 ft-lb with anti-seize) would have a similar effect as applying 200 ft-lb on dry threads.

 

You'll be fine. I found mine broken just before a 4 hour gnarly trail ride. I went on my trip still. Drilled it out the next day and replaced.

 

Three major aftermarket vendors offer them in addition to Toyota OEM: http://www.rockauto.com/en/catalog/toyota,2010,tacoma,4.0l+v6,1445515,wheel/tire,lug+stud,7680

No need to run longer studs if you are using Toyota wheels. In fact it may be detrimental (tip of stud bottoming inside lug nut).

 

Check with autozone or oreillys they might have some studs in stock. The studs are just pressed into place

 

200 ft/lbs . . . YEAH!

Thanks guys. I feel better knowing this isn't a big deal, and I can fix it myself.
