How do you replace the oil pump on a Hyundai Accent?

if there is a problem with the oil pump you likely have bearing problems also if the car has low oil preasure and is not rapping or making a loud noise just run it till it blows ..if it is making noise go to a junk yard and buy a low milage used moter and install it the oil light probably came on, pressure sender bad, or you can just say the engine is no good it is well worth the time to change it an see how it goesn it does not take that long
