When you get the cover off, try and get a good photo of these #' on the ring gear. Try and find someone with a Macro setting on there camera. You may have to rotate a rear wheel to bring it into view. Both wheels need to be off the ground, use two jack stands, one under each axle tube.

Also try and get shots of the Side gear, and the hole I have circled.

And you are correct, do not try and remove anything but the rear cover.
Have fun.
