Ok, I have been noticing this noise for a while now and for some reason I thought that I was running over like a manhole or storm drain near my parking spot, but today I confirmed that I was not. Whenever I start the car from when it has been sitting, so the engine is cold, and I start to drive, within the first 25-50 feet I would say, I hear a clank, metal to metal i beleive. The truck only has 5,500 miles on it and there doesnt seem to be anything wrong with the driving. Is there something that disengages????? I have to reverse out of my spot, then I pull forward and like I said maybe 20 yards down the parking lot, i hear the "clank". Any thoughts would be greatly appreciated. Thanks.
