You are correct sir. The bushing tool (I won't call it a puller) was supposed to push on the outer shell, but the sleeves are so thin, that it proved hard to do with the socket I used as a pusher. The first side came out that way, but it slipped a bunch of times and I'd have to square it back up. For the next one, I tried a smaller socket that just pushed on the center sleeve. I thought it would tear the rubber, but instead, the bushings slid right out. Had I turned a press tool with non-radiused edges, it would be able to catch the thin outer shell better. Overall, I got the bushings out with no damage while still on the car and it took less than an hour for all four. My pics are on another computer, so I'll update the thread later with the pics.
