I call mine "Bob", but that is another story all together.
I did the job in my garage, but I have an arbor press and infinite patience. It is difficult to hold the supporting joint mount to press the part out of it. It is difficult to hold the supporting joint mount to press the new part in, and the new part gets feisty and squirms around, too. I am sure shops have a fixture, probably better than the one I fabricated, to hold this. Ensure you replace the "captured nuts", (wrong name, I know, but Bob was taken), which are inside the mount. They seem to have some sort of thread locking insert in them. Might be easier to pay someone who knows how to do it than to wrestle with it. Also, you need to be careful to indicate where the suspension is, as the threaded rod portion of this part adjusts the alignment.
