Got a sound that sounds like metal to metal ticking from under Center of jeep. Only happens while driving. Sounds starts at about 30 mph then we'll go away at about 75. Engaging clutch or shifting gears doesn't change the sound. Turning doesn't change the sound. Driving and then shut off engine and coasting doesn't change the sound. Shaking Wheels there is no play in front wheels or rear wheels eliminating possible bearing. There is no thudding when starting and going for a possible U-joint. While going faster the sound sounds like a bearing then while slowing down it becomes a very slow metal to metal clinking like two rods clicking together. Any thoughts
