[QUOTE="HotLap, post: 1284746, member: 27013"] Sounds plausible, and now that I've been listening for it at warm start up it does sound like it's coming from the transmission output shaft/front driveshaft area. All of my F-150's over the years have had minor drive line "clunk" but the Raptor's is definitely louder. In the past the dealer would grease the splines in the tranny output shaft and the noise would go away for a while...just "life with Raptor" ;) thx! The GT350 makes several noises when you first hit the start button as well. If you have the clutch depressed and start it right away it starts in "Beast Mode" and your neighbors really like you for that, but if you turn on the car w/o depressing the clutch and let it cycle for several seconds (you can hear the exhaust valves opening/closing) then start it - it will start in quiet mode...but who wants that!!
