So a little pre cursor to the issue below. This past Sunday My lovely wife needed to move my truck since I was blocking her, and she said that as she pulled forward (no faster than 5mph) she put it in park before coming to a complete stop. She said that she heard a loud CLICK CLICK CLICK before stopping. So now when I am driving anywhere over 40mph and I completely let off the gas pedal...I get this loud rumbling noise and it shakes the truck pretty good. More of a vibration shake...not like a death wobble shake. But as soon as I ever so gently touch the gas pedal...it goes away. This intensifies when I'm on the highway 70mph and over.
