I removed mine myself with a sledge/air hammer, but to have it put in I had a shop do it. They said their press ran out of umph around 80% of the way in (Lemfoerder joints) so he had to hand hammer them in with a mega air chisel, marred up the edges a bit but he did get it seated all the way, vibration probably helped a bit. Cost $40 for them to do it, and all I had to do was drop off/pick up.
