This is not a good process by written directions. If by flat gray part you are referring to the rear portion of the diff which contains the cooling fins, no, that is not the location I suggest. I remember the diff housing being black, not gray, but I haven't been under the car lately. But, it is forward of where the axle shafts connect, not visible from the position from which the photo was taken. If you are inexperienced in this type thing, please get some on-site instruction from a competent tech.
