I need help trying to find out what's wrong with my power steering. It's leaking and no one can seem to find out where it's leaking from. They can see it leaking but unsure as to where it's coming from. All bolts have been tightened and the Lexus Dealer said that it's probably not coming from the O ring. A new pump has been put on and also new hoses. I have to put power steering fluid in everyday and even when there's some in, it still whines. What else could be the problem? Help :o
