Rear der. pulleys
My bike developed fairly annoying noise, which I'm pretty sure comes from rear der. It's very much like a bird chirp. The bike is 1x9, with Shimano 105 rear derailer (long cage). When riding under normal load, noise is very subtle in larger cogs, gets louder when getting to the outer (smaller) ones. Chirping is the loudest when changing gears.
I cleaned and lubed the chain, with no effect. Do I need to lube or grease the pulleys? It looks like there are no bearings there, just simple bushing in one of them.
TIA

A little spritz of light chain oil, or most any other oil works fine. If you really want to get anal, you can take the pulleys off, remove the protective covers, wipe out the shmootz that's in there and then lube them before reinstalling. Not too much lube though.

It should be a pretty simple job, only needing an Allen wrench to remove the pulleys.
