power steering problem
Hi, my power steering used to leak fluid and i would have to add some once in a while, last week i finally got the car checked at the mechanic and he said its the steering box. So i changed it and the car started making a tiny bit of noise when ur first starting to move, he told me that after i drive it, it will go away cuz there is air still in the system. So i drove it for a few days and it got worse, so he checked it out and told me the power steering pump needs to be replaced, so i replaced it with a used one and the car worked fine and the noise went away. 1 day later the noise has come back and i think its gettin worse, has anyone had this problem before, could the pump that i got be bad or is it because he didnt get the air out of the system, or could it also be that one of the hoses is leakin fluid and air is going in?????
Also the car has fluid under it but i cant tell if its the pump or a hose...
