so i got upper bracket for my pump today so i got it hooked up and put on the belt. It seems like it is working fine but i noticed it is making a lot of chattering noise. Sounds like a bad bearing or something, is there anything that commonly fails on those. The engine is a b16 i am not sure how long the pump has been on there but both the engine and car have under 65k so it seems weird that it would fail already. I saw on majestic they have all the parts so should i try fixing the pump or should i just buy a new one.
