Ok, so i have replaced the power steering pump 3 times now, rebuilt unit from autozone, each time i have properly bled the system turning left to right, etc. Its full on fluid each pump and it makes noise constantly, and whines more under acceleration when wheel is turned. My question is has anyone had this problem, and could it be something with the rack and pinion causing the pump to make noise? The rack is not leaking, and i dont know what is the matter with the pumps i am getting, do you think that its just a crappy rebuilt unit and i should complain and get my money back? Any input appriciated. Thanks.
