yes its a press fit, you need to find a socket that fits so it clears the housing but impact on the bush. then you just hammer it out. Once its out you can press in the new bush in. It helps to heat up the alum housing (I used propane, don't go crazy, just evenly heat it up some on the tail) put the bush in the freezer for an hour before time to install, it will go in with some light taps as it is shrunken, and the alum is expanded. You need to pay attention to the oil feed hole that is cast into the housing so it aligns with the hole in the bush.
one more thing when doing the heat/freeze trick, you have to work with some sense of urgency to take advantage of the heat/cold, as the bush will quickly heat up and the alum will quickly cool off once you start the process. just make sure that hole stays lined up.
