The first item to be inspected here is the driveshaft and u-joints; if they already havn't been done. The drivshaft should be removed and sent to a drive-line specialty shop for balancing , u-joint inspection, and yoke inspection. If the drive shaft is good, the diifferential mounting may be weak, or the transmission mount.
