So after about 40 minutes with a cold chisel and 4lb mallet I got the nut off the drag link bolt. The threads on the nut were toasted. Now I just need to get the damn drag link to drop. Was out there hammering and pickle forking(?) for about an hour now and the damn thing still won't drop out. Sprayed some PB, hammered all around the pitman arm with a ball peen and the mallet, tried to use a prybar for downward pressure on the bolt using the frame as an anchor point, and tried several combinations of all of the above. Stubborn son of a bitch.
