My '08 Caravan with the 3.3 has been making a light "clacking" noise while coasting in gear 5 - 10 mph. It's like the old baseball card in the spokes but metalic.
It's not happening during accel. or braking, and also not while in neutral (at speed or parked). It does not change with engine speed.

Any ideas? I'd take it to the dealer right now but the wife's within a week of popping our 3rd child and she's not crazy about not having the reliable car close!
