So I went to a tire shop recently and they installed lug nuts with impact wrench with too much torque.
I want to retorque them now. I have 50-250lbft torque wrench and I have the socket. What is the procedure of retorque?
I read some reddit threads. It seems that it will be fine if I do it on the ground, as long as I retorque lug nuts one by one, not all at once. I also noticed that I should do it in a star-shaped way when I have 5 lug nuts on a wheel.
The question I have is that after I retorque 4 lug nuts to the correct torque (80-100lbft), the remaining lug nut is still overtorqued to maybe 150-200lbft. So the wheel is still overtightened on that lug nut. The other four normal-torqued lug nuts have little impact on the wheel compared to the overtorqued one. Once I untighten the last lug nut, the strong torque will suddenly disappear. Then the four normal-torqued lug nuts simultaneously have the same impact on the wheel.
Then it seems like that if the lug nuts have already been overtorqued, retorque in a star-shaped way or a circular way makes no difference. The correct way seems to put the car in the air, loosen all lug nuts, hand tighten them, put the car on the ground, torque wrench them.
I guess if I want to do it on the ground, I can do lug nuts one by one in a star-shaped way. First tighten them to 50% torque. Then another round, tighten them to 80%. Then to 100% torque.
What is the correct way?
