I have a 2006 SC also and I occasionally do hear a clicking sound that seems to come from front end. I hear it sometimes when I switch from rev. to fwd movement, sometimes on a turn but i Only hear it once then wont hear it for a while. I've tried (sharp) turning the car in both directions at slow speeds but dont here anything like that so I dont worry about it.
Do you hear repeated cluncks during the turn? If so would have it check out as it may still be a joint problem.
