I was driving last night when I started feeling vibration. Pretty quickly it developed into knocking so I pulled over and had it towed. Towed it to my mechanics and found out my lug nuts had on the driver side front wheel had come loose and I actually lost one of them. My mechanics said this is very unusual and he suspected someone had tried to steal my rims or sabotage my car. What do you guys think? Has anyone else had this happen? I had suspension work done 3 weeks ago but my mechanic assures me he used a torque wrench on the lugs.
