Yes, you will need to pull those babies out.. they have to put all the pcd stuff in an oven and bake the stuff, im not sure if you need to take the bearings out tho, you should probably get some new ones while your at it anyways.. Actually, a good way to get them out is put them in your oven at home and bake them a little bit and they should slide out with a few hits. I used a socket, dont remember what size, to get mine out.. it should fit over the outer lip of the bearing.. the first one youll have to knock out with something skinny and long( ), i used a punch trying not to damage the bearing although.. not like i used the same ones...
