Strange Noises at Speed

Today my boxster starting making a clunk noise when decelerating at Speed in 4th and 5th. Somewhat rapid, but not as fast as something like engine knock would be. Only knocks when the throttle is not engaged. Increases in speed with car speed. And I can hear it from the rear passenger side. Any ideas?

CV is my guess.

Would it behave like that only in those circumstances, though? I suppose I'll look at it tomorrow when I get it jacked up. What do I look for? Torn boots?

Slack between acceleration and deceleration? Mine had a lot of slack.

Bearings made a wob wob wob sound.

Just got the wheels off a couple days ago. What I found was kind of unnerving. The CV axles are fine, no tearing or anything on the boots. The problem was in the lug bolts. Somehow, only on the right rear wheel, all of them were loose. I know for a fact that I tightened them to spec with all the other wheels a month ago when I had the car up on jacks. So either they're coming undone on their own, or something else.
