That crush sleeve is incredibly stiff. It takes a long bar to torque that nut.I don't think you could collapse it in your driveway,on jack stands. There is so much wind-up in the springs I doubt you could get enough travel with a long bar. I finally built a yoke anchor tool. On a lift it is pretty easy now.
To your point, it took a 4' cheater bar slipped over the 3' breaker bar to bust it loose. I know it gets harder and harder to bust a nut as we get older, but this was ridiculous.
