Some Sort of Violent Vibration

Hi All, I have a 2005 Jeep GC Laredo AWD V6. I'm pulling my hair out trying to figure this out. When travelling above 40mph, I get this vibration that shakes the whole Jeep. I'm pretty sure its coming from the front. It doesn't happen constantly though. Its intermittent. Maybe a minute or two in between vibrations and the actual vibrations last for about 5 to 10 seconds. It only happens when keeping the accelerator in a consistent spot going a constant speed (not accelerating, nor slowing down). If I accelerate, the vibration stops. If I slow down with using the brakes, it stops. Shifting into neutral while driving will make it stop as well.

I have changed the front axle isolator bushings (the top one was gone). I have a rebuilt CV joint in the front driveshaft. I replaced both CV axles. Checked the tie rod ends and ball joints and all are good. The front tires are balanced fine as I took it into a shop to check them. All that and I still get a vibration.

Has anybody had to go through something like this? What could it be?

Please help,
Thanks

Possibly a phasing issue between the front and rear driveshafts. Try loading the rear end down so that the suspension squats a bit, see if the vibration persists.
