This was the first time I had removed the wheels on mine. They are the stock wheels and stock lug nuts. When I put the wheel back on I tightened all the nuts by hand before putting any torque on them at all so it definately wasnt an alignment issue.Did you guys rotate or remove your tires several times before they broke? Are you using the same stock wheels and lug nuts?
The only thing I can think of... is the wheel wasn't installed correctly and the hub was rubbing on the bolt. I know I have to always recenter my hub sometimes before putting my wheel back on.
Of course there are manufacturer defects.... just seems odd with so many of us not having any issues at all.
Like I said before, from what I could see the other 5 studs looked perfectly fine. The one that broke however, was visibly thinner at the back of the stud where it broke, and on the thinner part was discolored black as opposed to silver like the rest of the studs in the hub.
Just to put size into perspective I just measured the broken stud, and a replacement stud. On the replacement, measured from the point of the thread I got .467" in diameter the entire length of the stud. On the broken stud, measuring from the point of the thread .467" (.25" from the tip of the stud), .437" (.25" from the stopping point of the threads). That's almost .030" of deviation in diameter throughout the length of the stud.
