So I've got a loud noise coming from the top of my serp belt and I want to narrow down the issue before I just start throwing $$ at it. I've narrowed it down to the P/S area. I've got a slight wobble coming from the pulley and am curious whether I should just purchase a new pulley or if the whole pump needs replacing. How can I tell if the pump is on it's way out? I don't see any leaks but it is pretty loud. Also seeing a wobble from the lowest pulley in the serp belt too. Not sure but think it might be AC? Might make sense considering my AC has been REALLY loud recently too.

Anyway, advice appreciated. Let me know if there is a check I can do on the P/S pump or if it's probably best to replace the whole thing. Thanks.
