Here is a straight on view of the front diff with the cable and housing removed. Note where the fluid is leaking.

This is the view with the camera at the front of the Blazer looking back. The cable is installed, but is not being pulled on. Note that fluid also seems to be leaking around the sides and not just from around the CAD piece.

This is with the cable being pulled on.

This metal ball dropped out of the plastic housing. I'm not sure where it belongs and I haven't seen any mention of it from anyone else.
