I was putting on my wheel spacers the other day and when I got to my drivers front wheel well I saw what you see in the picture. It looks like on the differential or whatever the big silver thing that connects what may be called an axel to the engine, there is a place that a screw could fit. It almost looks like it’s missing something. You can’t miss the big round hole in the pic. Did I loose a screw or something? I’m obviously not a experienced car guy. Thanks for any help you can provide.
