Thanks Bimmerfan. Good points.
I was going to try glueing the seals shut as described on the 7 series board. That would be first step before getting more extreme.
So far i just top off with steering fluid, maybe once a year. I just expect it to get worse at some point. The car was built in 2007.
Appreciate the reminder.
