Hey all - Recently my power steering pump has had a bit of a squeal when the car is on. Not super high pitched, just pretty consistent. It's fairly noticable when idleing. At speed, the engine drowns it out and it cannot be heard. I don't think that it's the belt because when I pour water on it the noise remains the same. The belt tensions are pretty good. I recently adjusted my valves and turned the engine over using the power steering pump bolt. The noise started some weeks after that. Is this something to be worried about? My initial thought is maybe a bearing is shot inside the pump.. However, I know very little about the pumps used in these cars so I'm not sure what to point the finger at. Should I give this immediate attention? It's been around for about a week and a half, and hasn't changed all that much.. I drive ~70 miles a day commuting to and from work.
