Over-torquing Lug nuts.. Myth or Real
This mechanic to whom I took the car for tire swap, just used the pneumatic impact gun to tighten the nuts. He went in star fashion and did it once round for all five nuts.... Then he did one more round of tightening with the gun for the 4 nuts ( left out the nut with lock )
When I asked what about torque wrench, he said dont worry they wont fall... I said well must have over torqued then and must be difficult to loosen manually if required , he said dont worry they are 90 ft pound, only a woman might not be able to loosen but you can...I said well OK and drove off
So with two rounds using impact gun are they over tight? I have a breaker bar and torque wrench.. Should I loosen those a bit and re torque or just leave them in there...What hard can it cause..
