Do not attempt this job without access to the special tools to remove and install (separate tool) the PS pump pulley. Don't even think about even tapping the pulley onto the shaft.
If you rent or buy the tools, double check they are the correct metric thread used in your MY. I had some difficulty finding the correct tool. The SAE tool will appear to work but will stop after a few turns. If used, there are not enough threads engaged and it will strip.
Suggest performing a through inspection. Look to see that the leak is not from the power steering pressure lines at the swivel connections.
With the correct tools, the job is not all that hard. Expect to tired forearms removing the pulley (same to install). Be sure to lub the tool before use.
Recommend getting extra telflon washers. Do not re-use. Heat the washers in a pan of hot water. Use the tappered end of a socket extension to expand the washer to fit over the connector threads. The washer will shrink back after cooling.
I have found that if on initial re-filling, if a power drill is used to slowly spin the pump (belt off), the bleeding process is easier. The center shaft will accept an Allen style bit. Stop spinning when any bubbles are seen. Repeat until no bubbles.
Upon initial start-up, shut the car off if a lot of bubbles are seen. Continued operation will spread ever smaller bubbles through out the system thus making bleeding harder.
Good luck.
