My Exp is a (2WD) 2000 with 197K on it. I've been getting a quiet "whump-whump" sound that gets faster with speed, resembling the choppy sound of helicopter blades up around 30-40 mph. It becomes unnoticeable at higher speeds, and doesn't seem affected by turning. It hasn't gotten any worse in the 8 months that I've owned the car. The previous owner apparently heard it too, but I think he just stopped investigating beyond the tires and cranked the radio up.
The other day I gave the car recommended maintenance to the tune of 2 new rear tires, alignment adjustment, and front wheel bearing repack. Haven't really driven it since then (ice storm), but am not counting on any of these changes solving the problem. If I discover that the sound is still there, what's the next thing to have the mechanic look at? All I can tell from my online research is that the issue could be rear wheel bearing, U-joints, pinion, hubs, loose wheel....
