You first have to separate it from the steering knuckle. Let the suspension hang without support. Pull the cotter pin and loosen the nut about 3-4 turns. Sometimes (not often) it will come loose on it own. anyways you'll have a gap between the nut and the spindle. Big hammer---hit the spindle near the nut where the BJ goes through a couple of times til it pops loose. Now you can support the lower control arm with a floor jack and compress the gap back. Leave the nut on for now for a little safety. Now you can work on the rivets further by drilling a hole in the center as large as you can go without damaging the A arm. I have a pretty good air chisel that I use to get in between the BJ and the arm to loosen it up. It's a little bit of work
