Power Steering Fluid Leak

[billdo]

Last week as part of my 100k maintenance I changed the PS reservoir and fluid. I did not have a leak prior to this. When I opened up the old reservoir I notice the fluid was quite low.

After replacing the res I filled it with fluid, and after that I noticed a leak. After parking the car there is always a small puddle of fluid. I figured I must have put a hose on wrong, so I took it all apart again and found no leaks at the hose connections to the reservoir. The alternator shows no fluid on it and the res is clean.

Now that the fluid is low again in the res the leak seems to have gone away. The PS seems OK, but something must be wrong. Any ideas?

Is at the rack? Do I have to remove the stiffener plate to find out?
