Closing cam shim

This is a cam I used to repair the door on my Kenmore Refrigerator Model 106.72003010. The right hand door would pop and click while opening and closing, and it would no longer close by itself. After some research, I bought a closing cam, part number WP67003638 or WP67003639 (mine was gray, but I can't find the part number now).

A phillips screw and three self-tapping metal screws hold the top hinge in place. When that's removed, the door lifts right off. I pulled the old part out and it didn't look damaged. Swapping in the new part and reassembling did not fix, so I pulled it apart and looked at it in more detail. The closing cam part fits into a socket in the door that has a matching cam to ride against the closing cam. On my door, the entire socket was rotating within the door. The expanding foam appeared to be all that was originally keeping it in place. While the closing cam itself is replaceable, the socket is part of the door, and is not individually replaceable. A
