A while back I cleaned up my engine and afterwards notice a sound coming from my engine. At first I thought it was my belts, use some belt dressing but noise remained. I thought it may be the water pump pulley or bearings but to make sure I removed the belt and ran the engine... no sound. After going back and forth found out its my Power Steering pump making the sound. I dont have any leaks coming from it yet, steering works fine so it has to be the bearings.
If its the bearings do I need to replace the whole pump? I tried spraying some lubricant on the back of the pulley and the sound kind of went away but came back within seconds.
