As I drove home from work today my car began to vibrate and shake violently after a short time I realized this problem wasn’t getting better, only worse. I pulled over. Come to find out that two adjacent (out of the four) lug nut bolts on my front passenger tire were completely GONE! Broken off. …

The only thing that can cause this is if the wheels weren’t torqued properly, or if the lug studs were stressed. There isn’t kind of lubricant on the lug studs is there? Tester

You will see competent tire stores using a hand torque wrench to do the final tightening. At some point, a high-powered impact wrench over-tightened and damaged your studs…
