Yes, I did it this weekend. You are correct, it's a metal reinforced seal, but came out pretty easy with a screwdriver pressed along the edge. It did end up all bent to hell, but I was replacing it anyway.Put the new one in by positioning it and pressing it in as far as I could with my fingers, then tapping it in with a 17mm socket.
Nice, good to know. But since we both just changed it with over 100K, we prob won't be doing it again!
