I have a 2001 Pathfinder SE (3.5 v6). I have developed what I think is a power steering leak. The leak appears to be coming from a hard line on the drivers side front of the truck, from behind a retaining clip. I live in the midwest so I drive on snowy, salted roads, so it seems like I could have somehow gotten something behind the clip that either rusted or abraded a leak in this line.

My questions: does this sound like a power steering line? If so, which line is it (return line? pressure line?) and where can I purchase one most economically? If this does not sound like a power steering line, any clue what it is? The leaking fluid looks like PS fluid, and my truck keeps running low on it as well.

Thanks in advance.

 

Any help would be appreciated.
