I have pressed in many different types of bushings, bearings and other items. It was really hard. I was able to push both of them out with a port freight press. However, I had to take the control levers to the machine shop to press in new bushings. This is not a product issue, it is a Subaru design issue. It wasn't a major setback and it only cost me $50 to install them. In terms of performance, they are great. My car drives great. My old LCA jacks have burned out. You are much more powerful. I don't think they will break like stocks do.
