I have just snapped a stud on my rear left today and the nuts were loose. Also rear right were loose. It also happened to the rear left in Dec and completely lost the wheel. In Dec it was on standard gu steel wheels running 33inch AT's and today on 16x8 -13 steel wheels running 35 inch MT's. No I don't torque them but I do know how to do up wheel nuts. Never had a problem for the 2 years of owning the gu before Dec and never had a problem with any of my other cars. What issues could be causing this? I did notice today the rear left had no wheel weights on it but didn't feel any vibrations.
