Not really sure if this fits the general discussion forum, but since it applies to almost every vehicle ever made, I started here.
The question I have about wheel studs relates to the fact it is a bolt. My question is why with bolts like head studs/bolts can you only retighten them a couple times before they are considered bad? Even flywheel bolts only get used once. To me wheel studs are some of the most important assemblies on your vehicle. Yet, if you follow retune maintenance, like tire rotations and replacement, you will re use these bolts/studs a whole bunch of times. Is there something I am missing like they are made of different alloys or hardened to different standards. Or am I missing somewhere that says I should be changing them out after 3rd time I tighten them?
I have been to a few local tire shops that hammer them on with an impact wrenches and no torque values measured. Been guilty myself of twisting the old 4 way around until I saw little stars in my vision. Yet still they hold up without question. Recently one of my crew trucks did suffer a rear dually failure at the wheel studs. Now, I do know that 2 days prior another crew had rotated the tires, so I went with loose hardware that lead to that failure. After further inspection, all the other lug nuts on the truck were loose lol
So what gives? Anybody have an answer??
