thinking maybe its the pitman arm
Hello. This can be caused by a few things. Most of the time it is caused by an intermittently failing power steering pump. I usually start by checking the power steering pump belt to make sure that it is tight. A loose belt will cause this. If the belt is tight then I check to see when this occurs. If it happens off and on when the vehicle is not moving then most of the time it is the pump. If it occurs are certain spots in the movement of the steering then it may be binding in one of the steering components. At that point the vehicle will need to be put into the air and the front end checked for binding. It can also be the steering gear box, especially if the fluid is very dirty.
