The possibility that a second tightening event is possible doesn't mean that the joint "needed" it. It just means that it is possible to go tighter.
This is the case for nearly every joint I have ever tightened. if I wait one day and turn the wrench again there is a possibility it will turn a little more ( I studied this at work about 15 years ago). if I turn the wrench up it will go a little more (which of course seems obvious). if "more" means that something was too loose then we would never be satisfied until the bolts were twisted off.
It is not reasonable that a wheel will fall off after driving away from a service shop just because someone didn't re-tighten - wheels would be coming off all over the place.
The original torque specification will have headroom for tolerances, embedding and twist of the bolt.
Wasn’t implying they would fall off. I’m not a expert mechanic. All I was saying is when I recheck my torque wrench will turn some a fraction...not much...(maybe half a turn ish at most) until it clicks again. Others it clicks before turning them. Which leads me to believe the lugs were no longer at 90 ft-lbs (of course there is some degree of error based on the accuracy...or lack thereof) of the torque wrench used. I’m not intending to make it tighter...just verify they are still at 90 ft-lbs.
I also wasn’t implying the lug needed it or otherwise all hell would break loose! Lol
Is it not possible that a fastener would not be at the same torque in this case where the wheels are spinning/vibration, etc? I’m curious now about the engineering principles involved now lol
