The surest way to get it out is to remove the link and use a press to push it out and push in the new one.
I made a pusher installer from a steering wheel remover tool. Had to make a backing plate that would fit behind the link. It works pretty good.
Make sure the pin is not swollen on the part that was driven into the link. If iit is grind it down to the level of the link before you push it out or you could enlarge the hole in the link. You don't want to do that!
I sometimes use a punch of appriate size to drive one out but have to have help. Somebody to hold a heavy bar behind the link with hammering on the pin.
