Hi community I need some major assistance, on finding out the part number and name for item 2 in the diagram below. This part broke on me on 4/18 as I was driving heard a loud pop and then several after until I reached the mechanic. My mechanic stated that he could get one from a salvage yard or order one from ford at a higher cost. Of course I want to get one myself even if it comes from a salvage yard or if I order it online. I need to get this done as soon as possible given that this is my daily car. So in the below diagram I need to know the part name and part number for item #2 in the diagram. Also I need this for the right rear. I have a 2001 LS Base V8. If you guys know of a website I can buy this part only or any info would be great. I have found that you can buy the whole assembly but I do not need the entire assembly just that one part. Thanks guys!

Here are two photos of the issue:

If I get the part from a salvage yard I have a tool set but the center nut what size is that? I know I would need a breaker bar as I do not have an portable air compressor to take to get these bolts off. Thanks again guys.
