Can't get nut off LCA pivot shaft w/ poly bushing (shaft spins)

Just be aware that a swiveling impact adapter dissipates part of the impact force. I end up removing any swivel and extension if at all possible in really tough impact situations. But you'll still be way ahead of anything else you've tried. I'm a bit skeptical on being able to get much counter force on a flat ground on the threads; it's just not very large. Hpe you get it!
