The ball joint piece, with the threaded rod, can be driven out but there will be a lot of rust from the metal retainer. The bracket is aluminum.

You need the bearing bracket bushing,

When you look at the service manual, you will see the guide rod mount being driven in to the bracket with a small plastic hammer on the edge. I used a large, ie 25 mm wrench, on it's side and on the outer metal portion. Don't use a press on the center of the back portion. I did this and had to replace the mount after a year. It was damaged internally.

I replaced all the rubber bushings in the front suspension, as well as the ball joints. I bought a sprint compressor and did one side at a time.
