Oh my, I did not even try. I went to TRE and Dave helped me out. He used his impact gun and the proper tool to remove the nut. Even his mechanic struggled but finally got those suckers off. All rust welded on
I would prepare myself to go to the wrench with the A Arms removed from the car.
Also, when you re-install the sway, Wayne recommends you release/remove the bolt holding the sub-frame bar up (aluminum car-bar), this will release pre-load so you can slip on the sway bars. The alternative may tear/rip the new sway bar bushings. Ask me how I know.
