Hi my name is***** will be glad to try to help. Check all your engine and transmission mounts and driveline u joints and shafts for play and for a possibly dry cap causing a vibration. If the driveline checks out okay then check the transmission oil, filter, and suction screen for metal/debris indicating an internal problem occurring. Also check for any damage to the wheels or uneven wear of the tires, etc as well as loose or worn yokes or bearings into the axles or transmission. check for any signs of metal in the differentials indicating internal problems there as well. Let me know.
