If the wrench clicks when the nut is stationary, you're looking at static friction, not necessarily proper torque setting. The bolt/nut has to be moving when the wrench clicks.Bird Freak wrote:

Quite the opposite, if the bolt is checked and it didn't move, it can't stretch. If it did move, then you are just doing a proper torque.

Do your buddies use cordless impact or air impacts when installing their lug nuts? They could be over torquing the studs from the outset and the torque wrench is just a placebo. A torque wrench has to move the fastener to be accurate.

Maybe it’s the use of all these quality Harbor Freight torque wrenches. 😉

I have probably serviced and we have sold Thousands and thousands of 5th wheels and regular towables over the years. Maybe I have seen 2 or 3 with broken studs over the 30 year we sell and service. So, if you have a few buddies having this problem, then it is something THEY are doing. Doug

I've got 3 axles and have never lost a wheel stud. Perhaps people are using too much torque.

Personally if I was worried about the torque of my lug nuts, I'd dial back the torque wrench to 10-15 lb.ft below the spec and see if they're tight at that setting. If they are I'd call it good.
People who constantly re-torque things are their own worst enemies.
