Where did you order these from? I am having a heck of a time finding them.

Wellllll crap! This just happened to me as well on my drivers side on a rust free vehicle.
About a year ago I did a few turns with a breaker bar when adjusting my AHC pressures. Everything turned fine then. I didn't jack up the vehicle.
Fast forward to this month and I did a big front end overhaul and had everything apart including these. I used an impact to loosen them which didn't seem to do any damage. When I put them back together I had the truck still on jacks and hand threaded them in and all seemed well. As they got tight I used a breaker bar again. I got the passenger back to the marks, but the driver side started to get pretty stiff as I got close to my paint marks. I tried a cheater pipe on my breaker but then it got REAL stiff. So I tried to take it back off and it was just as stiff. UH OH. Something was not happy. I could barely move it with the breaker.
So I just went to town with my mid torque impact and after a solid minute on and off, I was able to get this mess out. Thank goodness I was at least able to get it out.
What a bummer! Maybe I damaged the threads when impacting them off? Maybe these threads need to just be clean and there was some grit or something that started the galling? Seems like in the future it makes sense to try and use some compressed air to blow off the threads clean and/or use some PB Blaster to help reduce friction here? Seems like if you have these fully apart you should grease the threads?
Everything looked fine before the carnage occured:

Trash isn't responsible for that damage; the threads were overloaded and failed. V threads can only handle so much pressure before they fall over; that's why power transmission screws have square threads - thicker cross section = stronger thread.
There isn't any need to add lubricant to the threads. If they don't turn freely without load, there's something wrong that needs to be corrected.

Yeah, the majority of that damage is of course me pulling that bolt back through the nut after the initial bad thing happened.
I guess I'm still trying to figure out what that bad thing was. What did I do wrong here?
I was about 5 threads from the bottom of the nut when this got REALLY tight and when things started going south. This picture shows roughly the positioning of the bolt within the nut when it got stuck. So whatever it was, it was up "high" in the nut, and the majority of the threads in the nut and bolt were fine.
Welp the good news is that the new one is nice and clean and fancy. And installed just fine. Interesting to see there is some sort of light red coating on the bolt. I still added on a touch a grease as well out of paranoia. Just used hand tools only to tighten it, and it screwed on pretty smooth.
