I think the Rack was leaking slowly prior, due to the cross member being wet and theres fluid in there.

Lets just say Brake Fluid was in the PS lines for a while and turned out to be a really cool Pudding like consistancy. I took the resovior out, cleaned it out thouroughly, and replaced it. Didn't clean the lines due to limitability, time and lack of tools. This was after the PS let go.
Bill Cosby would have been proud! So I'm suspecting the rack is offically fucked.
