The nuts do loosen.... even seen it to the point where one broke. Of course that guys was a work truck and no-showed three times for his appointment. Funny thing is that your steering wheel becomes waayyyy off center when this occurs. His junk was talking to him, but he wasn’t listening.... I tightened dozens of these before the recall came about. I had a couple friends do their own thing after telling them what the recall entailed. One drilled and tapped holes in the nuts and put set screws in. The other just tack welded a 1/2 inch strap from nut to nut that could be easily cut and ground off if he wanted to adjust it. Have had a few others just make sure they were tight and marked them to keep an eye on them. Even if the nuts are welded it doesn’t take too much effort with a cutoff wheel to make them “adjustable” again.
