When just taking off, either forward, or reverse, there is a clicking sound, like a rock in a hubcap, but very soon, stops, actually I had the tire off the car, and turned the rotor as fast as I could, by hand, which was really slow, and the clicking was there, just for a few seconds. I thought maybe the rotor was rubbing on the dust shied, but that does'nt seem the case. When I have the window down, I can hear is slightly, not very long. When I had the tire off, I checked the cv joints, no torn rubber, no grease flying around, I pushed in/out, up/down on both ends of the shaft, nothing seemed out of the ordinary. The only thing I did notice was the strut rubber, bellow, was torn on both side, and looked like some oil was leaking, so I will have to replace both struts soon, but I don't know if that would have anything to do with the clicking sound. Like I said before it sounds like a BB in a hubcap, but in a sense that does'nt make sense, because the sound stops way befor centrifical force takes over, know what I mean??
