Stripped/Bent Wheel Stud

I'm extremely careful when changing my rims and always break loose by hand with breaker bar, then finish with cordless impact, hand tighten at least 8 turns, hit with impact, then torque wrench to OEM specs.

I just bought my new rims recently and did my 2-3rd wheel change with them after an autox yesterday and stripped/cross-threaded/bent a front wheel stud real bad. I lost a socket in the process, but I got the lug off of the stud, but did I do something wrong here? Could it have been the shop where I did my sway bars using their air gun while I was working on the back?

I have had the fancy ARP wheel studs for almost 4 years and decent quality steel open-ended lugs (2nd set), but did I over-torque or do the wheel studs need replaced every so often too? Could it have something to do with the new rims? I have noticed that the front rims sometimes need more turns of the torque wrench once back on the ground before it clicks...

Eh. 4 years is old for studs.

Way back when, CR guys recommended lake testing them every 1-2 years.

Throw them in a lake. If they float, they're still good.

Agree that is old but they shouldn't strip or bend in that time.

I guessing the shop cross - threaded it

Thanks, I ordered new stuff and noted for future regular replacement. I suppose a few spares wouldn't hurt either.

I just ordered new studs for the DSP car. I am doing both front wheel bearings and figured it's probably time. Both those bearings and the studs have been on the car since 2013
