I have to replace the Pressure and Return hoses. Anyone done this and have any suggestions or advice? How hard is it?

i might be able to tell you by sat night if no one knows by then, my power steering pump is dead on my bonny, makes a horrible rattleing noise at idle, sounds like rod knock in fact, but the noise goes away once its above idle rpm. i did notice i leaked ps fluid so new hoses might be in my future.
