I also learn that rule of closing QR in Richard Ballantine's book.

Did they have a lot of miles in heavy rain, or is it possible you or someone else washed the bike with pressurized water and got water into the hubs?
I bought this bike in the end of Jan in 2009 and only have put 2100 km (~ 1300 miles) on it. I didn't ride it in the rain nor washed it with water (I only wrapped it with a cloth)

This wheelset (Alx-200) is not in Alex's category. I guess it should be very low-end, but it shouldn't be worn out so soon, right? (Besides, I'm a light rider)

Before I took this apart, I just bought a hand-built wheelset (1380g in total). Wow, what a big difference, especially on climbing For the record, my bike is Fuji Finest RC.
