“Except on some Chrysler products up into the early 70s, cars with spinner hubs, some heavy equipment and some military vehicles.”
I was a left-handed teenager on a military base overseas. On a cold, snowy winter morning, an Army lieutenant colonel in our apartment building was having a hard time with a flat tire on his military vehicle, a jeep I think. He was a desk-riding officer and small.
My mother said I was bigger and younger than he was and to go out an help him. I went out and he said the lug nuts were frozen. I grabbed the 4-way lug wrench and spun them right off. He stood there for a minute and then said, “You turned them the wrong way!” I answered, “Sorry, sir,” and went back inside. :-)
I was mostly sorry I had helped him, but my mother had been an Army sergeant and you did not argue with her. I had no idea the threads were reversed, I was just a left-handed klutz.
I’m not understanding this left-handed problem with tightening nuts. The nut tightens when you turn it clockwise regardless of whether you are right handed or left handed. Why is this a problem?
