Well just FYI, my car doesnt make that noise anymore b/c about a month ago i think the part that was making that noise finally went out. Now it sounds like shutter/clacking coming from the transmission/driveshaft area and its also making noise around the differential so that sound it used to make is now gone. The car, of course, still drives perfectly. No power loss what so ever and every gear goes in good. Taking it to the shop today! so i'll let you know what my problem was... might be the same ****.
