2002 CRV clicking noise after belt change

Last summer I replaced the belt on my 2002 CRV. The vehicle was running fine with no issues or strange sounds, but after replacing the belt, almost immediately it started making a clicking sound from the passenger side of the vehicle when the AC compressor kicked in.

I could see the tensioner jumping and that seemed to be where the noise was coming from. I pulled the tensioner off and the bearing was a little rough, but not too bad, and I just figured that the spring had grown weak, and perhaps a combination of the strain from putting on the new belt, plus the belt being new in general probably caused the thing to go out. I replaced the whole tensioner assembly, but the sound has persisted.

Over the last year have taken the belt back off several times and checked all the other pulleys for slop and roughness, but nothing really jumps out as being the offending culprit. I didn’t want to start throwing parts at it, and figured that the source of the noise would reveal itself over time. This isn’t a car that is driven daily, but as near as I can tell the sound has never gotten any worse. It’s just really annoying and it just sounds like something is really wrong.

I don’t think it’s AC specific either, because I can occasionally get it to make the noise with the AC off if I put the engine under strain, like really gassing in up a steep driveway.

(not my video, but this is exactly what it looks and sounds like: https://www.youtube.com/watch?v=yaS2dd86EDE)

Any suggestions?
