Getting it out is easy. It's the pressing it in that's the trick.

I used the tool when I did mine (that's my car on Bruno's page). If you can't get the tool, you can fabricate one up. There's been postings in the past on how you can make one.

The only trick with this job is getting a tool that will work. Other than that it's very simple. However, no tool = major PITA.

I suspect shops get a lot of money for this job because either a) they don't have the tool and have to fight through it with extra time or b) they have purchased the tool and know it costs an arm and a leg and thus charge accordingly.
