Stock 2000 Explorer XLS/4 door/4x4/5 speed auto/4.0 OHV.
150K miles.
Once I get up to about 30MPH and above and am just cruising along, with my foot lightly on the gas pedal, there is a vibration. There is like a humming/groaning associated with this vibration (maybe it is the noise the vibration is making)? It isn't a scraping, grinding, or squeaking noise. Seems to vibrate and make the loudest humming/groaning at 60-65MPH. Seems like it is a chassis or drivetrain vibration.
If I step into it, and accelerate, the vibration and noise seems to go away.
If I let off the gas pedal and coast, the vibration and noise goes away.
It doesn't feel like a tire vibration. The steering wheel doesn't shake. Tires are good. Tires are properly inflated.
It almost seems like it is coming from the tranny, but I can't tell for sure. The tranny shifts fine. And it doesn't seem to make a difference what gear the tranny is in, there is still a humming/groaning noise and vibration.
New tranny fluid and filter within the last 3K miles.
New Moog balljoints, within the last 10-15K.
New shocks all the way around, within the last 2K.
New rotors and pads all the way around (new parking brake shoes too).
New Moog inner tie rods, within the last 500 miles.
Alignment just checked and it is good. There was also no play in the front wheel bearings.
No noticeable play in the front or rear driveshafts (ujoints, or where they go into the tcase, or in the slip joints).
