Message: <blockquote data-quote="Joe Dirt" data-source="post: 578241" data-attributes="member: 62841">Greets!  Running an '03 Sport Trac that has developed a curious leak that has left me dumbfounded.  In the driveway, when turning the wheel back and forth, everything looks and feels fine.  No leaks, fluid levels normal, etc. Same as if I were to run the truck down to the mailbox or around the block.But if I run it down to the local Chevron or HomeDepot (>1mi.), when I get out I find an explosion of (what looks to be) power steering fluid everywhere - squirted into the fan which makes a huge mess; no obvious cause of the leak is found, and the fluid level remains the same. Brake fluid also normal - can't think of any other fluids with this coloring/consistency. Fluids are not frothy or discolored.Was wondering if I have a bum steering pump that, under load/acceleration, is leaking?  There looks like there might be a leak of sorts back where the reservoir leads into the pump, but of course you can't see squat back there w/o taking off the pulley...Looking for any other suggestions as to where to look... vehicle drives normally - there was no impact in/around the power steering pump area.  Steering rack was replaced, but everything is snug and again no obvious source of leakage.... I would think that this mystery leak would cause an obvious loss of fluid, but so far things are fine.Thanks in advance!</blockquote>
