I was always taught not to torque when a hub was hot (after driving), but I changed lug nuts today and wanted to do the retorque after taking it for a drive as we have a long trip tomorrow. So I try it and the lugs are spinning way too much. I stop and remember the way I was taught. But then I start wondering why?
I use a non-contact heat gun and the lugs are at the most 100 F. No way the studs are going to change physical properties at those temps. So is it a torque thing? I don’t know that I ever really understood why that rule was the case. And when you drive into discount tire (or dealer for that matter) for a free retorque, how does that work? Any ideas?
