Add me to the list. I have a "cousin" of the X (mountineer). '98 5.0, AWD.
When running at 50-60mph under light acceleration I notice a vibration that shakes the whole truck - not just throught the steering. If I let off the gas it goes away. So far I've rotated tires, replace a leaking rear axle damper (horizontal damper that mounts to diff) with no improvement, and checked the trans mount. Front lower ball joints are only 3 months old and tight.
U-joints seem tight, but I did notice a bit of movement in the splined section of the driveshaft (where it slides in and out). I wonder if this is enough to make the shaft "whip" at certian speeds and loads. I'm going to pull the driveshaft tomorrow and see if I can get a local shop to check it out.
