I would just change the sway bar bushings. They are cheap and fairly easy to change. If the end links are bad, the sockets will usually show play that you can see when loading and unloading. And again, if you decide to just change them, they are fairly cheap and easy to change. Although the nuts are usually difficult to remove. So I just cut them off. Quicker and easier than fighting the nuts.

I still don't know what you are referring to as a strut bushing. There is a 'bearing' at the top of the strut that allows it to turn, but the noise it usually makes when bad is well represented in the video posted above.
