Yesterday, I installed the replacement power steering high pressure hose (#9 from power steering pump to disconnect under car) and found that the front hose (#1 from steering rack to disconnect under car) was leaking where the hard line enters the disconnect fitting). Since #9 was split in half, I wasn't able to tell if #1 would leak or not until I replaced #9.
For reference, hoses #9 and #1 are the high pressure lines and #2, #5, #7 are the low pressure return lines.
The installation of #9 wasn't too hard but it took a bit of fiddling (aka patience!) to get the hose in the proper position since it has several awkward bends and it fits fairly tightly up against the engine and there isn't a ton of room to maneuver around when working through the front engine access panel. Again, this was made MUCH easier by the absence of the a/c compressor.
Looks like the #1 hose shouldn't be too hard to replace since the connection to the steering rack is visible with the left front tire removed. New #1 hoses were over $300 so I bought a nice looking used hose for $150 from eBay.
Since the car was already up on the lift, I went ahead and replaced the brake pads/rotors along with an oil/filter change. I've done these two tasks so many times now that I could pretty much do it with my eyes closed.
