Scotty, My wife has a 2012 F150 4x4 110,000 miles . The truck has an intermittent groan/vibration at very low speeds (parking lot, backing or forward, coming to rolling stop, etc) without brakes on or off, gas on or off or steering. Also weather seems to not be a factor. I have done all routine maintenance on drivetrain (I am a retired diesel/automotive mechanic 27 years, so not too lost) but this has me baffled. Of course the truck will not make the noise when I want it to so that I could isolate the sound. The truck has that ecoboost 3.5 in it .(I know not a fan) no codes or any issues . Any ideas? Thank you, JT.
