So I just looked under my '98 Maxima, and it looks like I'm leaking power steering fluid. It's leaking from around the power steering cooler/radiator tube. It actually seems like it's leaking from around the rubber hoses. What parts do I need to replace, what are they called (the rubber hose, or the power steering cooler tube). Has anyone ever done this? How much are the parts, can I only get them from the dealer?

thanks
