I have taken off the right side wheels on the rear but now after reading other post I'm wondering if I may be turning the wrong direction for the (drivers) left side. I've tried to loosen one nut on the rear and it just won't come off. Are these left side wheel nuts left handed (loosen counter clockwise). Maybe that's why it didn't budge. I think I read somewhere that the stud has a number or something on it,They are 23mm and I do need to purchase an correct lug wrench. Be looking for the correct answer. Ted in Seattle.
