Rack leaking?? I think...

I had this same problem. During cold weather it looked like my power steeing pump was leaking fluid. I cleaned the pump and the 2 lines going to the power steering cooler below the radiator. Top up fluid with ATF+4 trans fluid (do not use power steering fluid). Drove it for a day and noticed the clamps on the lines had fluid dripping off of them. There are 3 clamps and 1 pressure fitting on these 2 lines. The clamps cannot be tightened and they lose their clamping force over time.
I replaced the 3 stock hose clamps:
With new hose clamps:
Cleaned lines and the pump again. No leaks for over a year

If you have fluid coming out of the boots on the rack you gotta either change the rack or buy a rebuild kit for it. I just changed my whole rack and all hose's. $200 rebuilt unit from autozone. Its not difficult at all. It you do change the rack you might as well get new outer tie rods as well. Make sure you get it re-aligned.
