it can be a motor mount. when the vibration occurs shift into N and then if it stops then it is your transmission. it could also be loose lug nuts, a bad wheel bearing, tie rod. or something else in the suspension.

Might be a hub bearing. Those make a growling noise when they are bad. When it is on jack stands you should be able to put your hands on the top of the tire and the bottom of the tire and move it back and forth. and the same with putting your hands on the right and left side of the tire. if you can and it moves back and forth then the bearing is back. but becarefull not to get the movement confused with a bad ball joint or tire rod. which could also be your problem but they dont make a growling noise

Hello, I see you may a lot of changes and replaced a lot of parts. We leased an Explorer the same Year as yours. In our case there was a slight noise as well as vibration. The problem was the Front Hub bearings, They were bad at 18000 miles.
There are a few things I want to suggest. The spinning of the wheels on the lift will not load the bearings. A Dyno table can get everything turning with a load on it. As your vehicle is a 4x4, most Dyno's were 2 wheelers. You would have to call to find one for a 4x4.
Next, if the new Hubs do not help, have a look at the rotors. They are also balanced. You can spin balance the Wheel and rotor as a unit with a floor motor. It's not the best way to Balance because tire rotation or even shifting the Wheel on the lugs will UNbalance it. But this method CAN pinpoint a problem if a Balanced tire does not spin true when bolted to the vehicle. You will know the Rotor is off-balance and which axle is causing the problem.
Would be interested to see a Post of what you found.
