Here is a terrible suggestion, but if it works.......
Put Some Lucus Stops Leaks Power Steering Fluid in there and see if the oozing stops, or if a thick gel appears in one spot. My wife's daily driver was leaking from the rack. Big bill to replace, vs. add a little Lucus to it. I read about 250 praises for this stuff. And we have had no leakes in 6 months, not to mention She puts at least 1000 miles a month on the car! (I know not the best way to handle it, but it has been a permanent solution to two leaking systems on two separate vehicles for us now.
