Hello. I have a 1970 Dodge Challenger. I need to change the tires, but don't know how to tell which lug nuts loosen left and which ones loosen right. Please Help.

 

the drivers side is the left handed thread side.

 

Unless it's an unmolested original you just can't tell for sure, but sometimes there's a marking on the lug nut itself. When I got my Charger only the right front had right hand threads! Baisicly when removing nuts on the right side you've just got to pay attention to how much effort you're exerting and if it seems excessive, well, try turning the other way. Good luck.

 

Every left handed stud I've ever seen has a "L" stamped in the end of it, unless you have capped lug nuts you should be able to see it.

 

I agree they are stamped with an L...Bill
