| Description of the problem | While completing a tire rotation, i placed the spare tire on the hub as a placeholder while i moved on to other wheels. I hand tightened the lugnuts holding the spare on (no wrench, no over torqueing). I left the driver front jacked up supported by a jack stand while i completed the rest of the tire rotation; the spare was never lowered to the ground and weighted, it was simply installed as a backup to my jack stand. When i came back to the driver front to remove the spare and install the normal wheel, 2 of the 5 lugnuts that i had hand tightened seized. When i attempted to remove them after application of penetrating oil, two of the studs snapped rendering the car entirely unsafe to drive. When i went around the car with a torque wrench set to the manual specified torque of 89 ft/lbs a third stud stripped. I do not know what caused the studs to snap or strip. I did not over torque the lugnuts, they were hand tightened less than 30 minutes prior. There is no reason for hand tightened lugnuts to seize on a wheel stud and cause the lugnuts to snap other than deficiency or weakness of the wheel stud. I have never over torqued the wheels; i always use a torque wrench set to 89ft/lbs as specified in the owner |
