I just replaced these today and have a couple notes to mention.
First, that duct that someone whacked a hole in to get access to the bolt on the driver's side is only held in place by two screws and a plastic rivet. No need to make a hole.
I was replacing the ball joints, so I just removed the torx screws and took the ball joints out attached to the arms. Once out, I just whacked on the end of the ball joint threaded part a few times and it fell out easily.
I saw where several people used hacksaws to slice through the outer wall of the bushing in order to remove it. I found it much easier to just push the old bushing down until flush, then push the inner rubber portion down maybe 0.5" just for clearance. Now you can use the new bushing to push out the old one. Plus, the new bushing is installed at the same time.
