No other parts that I touched give nearly as good a report. Looks like there’s two shock observers there.
Seems to me that a bad bearing in the pulley would be the source of the noise but you have more experience in this issue than I do, that much is clear.
Looks like I’ll need to take the radiator out to do this job. Once I get the parts.

You can do the job without removing the radiator. One of the shocks is the shock you linked, the other is a spring in a rubber tube. Release tension and rock that tensioner pivot back and forth. If it seems loose and sloppy, or if it feels tight and gritty, its needing replacement. If it's smooth, leave it alone.
Replace the shock and the spring as a pair. If the tensioner pivot needs replaced, you can do it without removing anything from the engine. It gets TIGHT against the fan, but you can do it. If the pulley on the tensioner needs replaced, now is the time.
Usually the tensioner parts are ok, it's just that shock that wears out and causes a heck of a racket. As mentioned above, the spring usually fails soon afterwards from stress, so it's a good idea to replace it preemptively.
