My 1999 GMC Safari 2wd has a vibration I cannot find. At 65 plus MPH vibration felt in seat, go's away when I let off accelerator. Wheels balanced, bearings checked, drive shaft balanced.

If it goes away when you are off the throttle, then it's coming from something in the driveline. Check the driveshaft, u-joints, differential and trans tailshaft bearings.
