Thanks for the suggestions! I was unsuccessful in finding the leaks with leak detector fluid, so I followed your advice about the bathtub (try explaining to your wife why you're giving your shock absorbers a bath ;-) ) I found that I was getting bubbles out of the RHS solenoid about every 2-3 seconds, and out of the LHS solenoid about every 10 seconds. I pulled the RHS solenoid off, and found the top o-ring was out of it's groove. After re-seating the o-ring, lubing with silicone, and reassembly - No Leaks! The LHS looked OK when I took the solenoid out, but I cleaned, lubed, and re-assembled it. Looking forward to putting the car back together, but the seals on both upper ball joints were torn so I figure I'll replace the upper control arms with new ones from NAPA while I have the shocks out.
