Does anyone know the meaning of a large, four inch long "X" on top of the differential crossmember? This is hand written in white crayon and is on the upper surface of the crossmember. You can't see it when the crossmember and differential are installed and there aren't any other markings on the crossmember other than the remnants of the "AC" sticker designating 4.11 gears in my differential. It had to have been placed there during assembly but it is a bit puzzling.
