Odd Broken Wheel Lug

[ARAMP1]

Take a look at this...

I replaced the wheel studs on my airport car, a Toyota Camry. After swapping out the studs, I realized I should have purchased new lug nuts too. The old ones were rusty and beat up.

So, new studs in two days ago with one round trip drive to work on them with the old lug nuts. The new lug nuts came in today, so I torqued them on.

Well, took the trash out this evening and noticed that one of my new studs was broken. Then, I got to thinking about the fact that I didn't drive anywhere today. The stud just fell off onto my driveway. Looks like a fairly clean break too.

Ghosts ?...Tire thieves ?..studs do not usually pop all by themselves..unless they were severely over torqued maybe,and had a flaw in the steel...
Given you recently bought the studs,chances are they aren't USA made..

After seeing some other "critical" parts like valve stems,steering components and suspension parts that failed ,or broke during installation in recent years,I tend to wonder if the countries they were made in are trying to wipe us out,without firing a shot.....

A guy with a 2000 Chevy truck I know had the idler arm snap off at the bracket,a few days after he had it replaced..parts store exchanged it as defective and gave him a new one--but blames the installer for over tightening it when it was installed (most likely with an air impact)..mechanic swears he had to use a ratchet,an air gun wont fit in there..

Well, I used a torque wrench to tighten them down and I'm sure it's the finest Chinese metal money can buy...

Always make sure you follow a torque sequence. I've seen lugs fail because they were tightened any which way and extra stress was placed on certain lugs. Also, studs need to be pressed in-if they are installed by cranking down on them with a lug nut and washers to draw them through the hub, it can weaken them considerably as it causes bolt stretch they weren't designed for. Larger lugs might be okay, but passenger car lugs made from suspect foreign metal will likely fail.

I don't care how u put them in that shouldn't happen just sitting in the driveway never driven.
