I am also learning about cars on a "as-needed" basis (whatever I have to fix to make it to work the next day..lol) I just rebuilt my power steering pump with a kit from
www.pskits.com and the seal kit was super cheap and they had an online diagram, I was able to do it in less than an hour. If you are going to rebuild your pump or power steering rack I would suggest taking a look on their site!!
