I must be one strong S.O.B.

I was checking the tightness of my lugs today since I rotated my tires last weekend, and I snapped a bolt completely off of my rear driver's side tire. I wasn't even pushing that hard or using my weight. That is the third bolt that I've destroyed in the last few months.

Has anyone else done this before? Is metal getting weaker or am I needing to lay off of the weights? :emb:

Lug studs, like all fasteners, have a number of times they'll accept torque before they're considered fatigued. It's a remarkably low number typically.

Replace the broken ones and don't put a wrench on them so often.

the metal has to be weak, ive put all my weight on lug nuts before and jumped up and down and they didnt break at all

Steel isn't what it used to be. I hear they put melamine in it these days. lay off the spinach Popeye.

do you use a breaker bar? do you use a torque wrench?

 

[Paladine71]

Yeah, an animal! Like a little bunny rabbit...:shame:

i was using the bar that comes with the OEM jack. My concern is that this is the third bolt (only one on the truck) in a short time. The other two were new and about the same size as the lug studs... Metal isn't what it used to be, it seems. :huh:

That OEM angled bar I believe puts angled torque on the bolts and could be part of the problem along with frequent changes. Those scare me as I am afraid I will bust a knuckle when it comes off.
Get a nice folding fourway and a torque wrench with deep socket and maybe a short extension, if needed to clear the tire. Purist would say the extension could change the torque but these are lug nuts not head bolts.

Two words: Torque wrench. Get one and use it.

I also recommend copper anti-seize or ARP assembly lube on the threads. Reduce the rated torque by 15% if you use either.

For the record, I have never, EVER, IN MY LIFE, had properly torqued lug nuts come loose. EVER! For this reason I no longer bother re-checking them after I install a tire and torque 'em. And I always use anti-seize on the threads to prevent wear. I've never broken a lug stud either.
