The noise sounds a lot like a heat shield. We have checked all the heat shields nothing. We eliminated the heat shield idea when we discovered that the noise could be stopped by switching the truck into 4x4 hi. There is a slight vibration at gas pedal, which can be felt. Some has mentioned a vacuum solenoid on the 4x4 unit. We have put new wheel hub assembly on both front, new brakes and ball joints but this has me stumped.
