I just replaced my steering rack boots, and on the passenger side a little bit of oil poured out when I cut the old boot away. Not a lot, maybe a tablespoon or two. The other side was bone dry. My manual says that with a ZF you should grease it, and the only thing that I could see to grease was the inner tie rod end. What else is there to grease?

Should I be worrying about my steering rack because of the oil leaking out of the one side? I have no idea when that leak started or how bad it is. The steering seems to work fine. If this is an early warning sign, is there anything I could do to baby this rack for a few years to get the most out of it before it goes completely?
