Broken wheel studs...

Needing some advice here...

Working on the truck over Thanksgiving, I went to remove the front wheels, and there were 3 studs that were sheared off!

There were 2 studs broken on the passenger side front, and one on the driver's side. Any thoughts as to what could have caused this?

I have never pulled heavy with the truck (max gvwr of 21k one time), and have never abused it offroad.

An air gun has never touched these lugs, coming on or off. I've always torqued them with a 1/2" drive torque wrench to 120 ft-lbs. The break doesn't indicate that the lugs were over-torqued; rather, the break is a clean shear break.

Since 3 of the studs have already broken, I'm somewhat reluctant just to replace them without finding the root cause.

Thanks, Eric
