Hi there!

Recently after visit at lubex we discovered that power steering in our 2005 Pacifica is leaking. Went to our mechanic, he diagnosed it as a leaking pressure and return hose. Are those two separate things? Can you buy this online? Price at the dealership he gave me was $590 which seem kinda high for such thing.
Now I found some online for much cheaper but I am not sure whether they'll work. Any advices, anybody had a similar problem? If anybody has a technical scheme of that it would also be useful.

Thanks
Sebastian
