I am utterly perplexed. I've been working on vehicles all of my life - everything from large trucks to expensive sports cars and I've never seen anything like this.

I was removing my wheels to install my AAL and I snapped, not a 2nd, but a third lug at the threads!

I know what most of you are thinking; "He must be using an impact wrench and he cross-threaded the lug nut when he put it on."

True, I'm using an impact wrench, but I ALWAYS thread my lugs by hand/fingers first before I torque them down.

I am just astounded by how easily I've snapped these off and I don't know how it happened [again] to be honest.

Please tell me I am not the only one having this problem or I am going to feel like an idiot (my wife would say I'm an idiot anyway...).

i cross threaded three studs when i was finishing up my lift, if that's any consolation.

you can get new studs and lugs for the dealer for cheap, i had a shop fix my screw up since i didn't have time to.

Is it just me or does it look like all of your threads are worn down?

I haven't had this happen or heard of it happening to any one.

Duck, check your PM's.

Have not had this problem and I have had my wheels off more times than I can count. Though, except for when work was done at a shop, the wheels are always put on by hand and torqued to 98lbs by hand.

Though, unless your gun is set to 250lbs or something, I don't see why they would snap like they did.

I have snapped a couple too..by hand and with anti-sieze on the threads. Oh, and rear axle only.

I change my wheels/tires a lot and I have never had this problem, though I have broken one of the McGuard security wrenches.

Yup.... it is only the rear axle. I've had the front ones off more than the back and they have been fine.
