Used on a 2002 Ford Focus ZTS power steering pump. I had a small shaft seal leak which was fixed with this kit. The instructions are good, but before doing this, make sure you have the right tools. You will need a pulley puller and an installer. Don't get one that grips the outside of the pulley. The pulley is overtightened and you simply deform it. I rented a puller/fitting kit from O'Reilly Autoparts and it worked great. The locking ring on the back of the pump was easy enough to remove but very difficult to put back on.
