Ok I'm desperate.. I changed my power steering pump and serpentine belt followed by my power steering rack and at low speed and maneuvering it's still really hard to turn left especially when the brake is slightly being used.. Also the power steering pump is heard during that time. Other than that the car steering is ok whilst accelerating and moving.. Anyone had this scenario before and was it remedied.. Tried Google and iv got different recommendations ranging from tire pressure to bleeding the system. Iv a 2010 police package. Thanks in advance..
