Does the flange rotate straight? Can you loosen your diff mounts and get it to straighten slightly? Have you done some frame measurements to check whether that piece of the frame is out? The diff should have been fixtured for welding. The 4 deg angle sounds pretty good being parallel like that. You want the angle to allow needles in u-joints to roll without having excessive angles.
