[s-cars] Hydraulic fluid hose leak

[Charles Rose]

Hey guys,

I noticed a leak the other day coming from the bottom of my car and I
thought it was oil but after closer inspection and the fact that only my
hydraulic fluid level is low I am assuming its hydraulic fluid.  I found the
leak coming from a hose connection right under the intake hose connection to
the intake manifold.  I believe this is the hose that connects the hydraulic
pump and the power steering rack, the leak is on the pump side of the hose
where it connects to the metal fitting.  I have taken a few pictures so it
can be verified that this is in fact correct.

In the first picture the arrow labeled number 1 points to the hose
connection to the metal fitting that is leaking. Arrow 2 points to where the
hose connects to a metal fitting on the other end and arrow 3 points to
where that metal fitting connects (which I believe is the power steering
rack).  Pictures 2 and 3 give close ups to where the leak is.  I checked
through the knowledge base and came across an article in the v8 section that
seems to be very similar to my situation -
http://www.audifans.com/twiki/bin/view/Audi/HydraulicHoses

In that article the person got his hose rebuilt for what seems to be a very
reasonable price compared to buying a replacement from the dealer $250+ in
his case.  What I need to know is if my situation is in fact similar to this
one, which means that an audi replacement hose is a last resort and having
my hose rebuilt by the same company he suggested is ideal.  

Also what is involved with removing/installing one of these hoses are there
special tools/connectors/seals or anything else needed? It seems to me that
a hydraulic hose carrying a lot of pressure must have a pretty secure
connection to keep from leaking.  However I really do not have any
experience or knowledge when it comes to hydraulic hoses/connections so ANY
information on this subject is appreciated and the sooner the better since I
don't really want to risk this leak getting worse and probably won't be
driving much or at all this I remedy this problem.

Thanks,

Chuck
