Just for info: I "regrease" noisy serpentine belt pulleys and it's easy.

Gently remove one of the seals. Clean out what's left of the old grease.
Jam some new stuff in but don't fully pack it and then reinstall the seal (the seals don't have to be in perfect condition).

I first did this as a stop gap because there was a delay getting a new pulley from my parts supplier.
- I ended up running the "regreased" pulley with no issues for well over 60,000kms.
