Hello,
before attempting a bit of DIY you should really be competant enough to recognise the correct parts used on your car. If you're not able to do that it would be wise to take the car and leave it at a garage for them to do the work. then you would not be able to blame everyone else for probably asking for the wrong part and then not knowing how to recognse or fit parts. No wonder it made a terrible noise. For a beginner like yourself I would suggest a HAYNES manual as they will tell yu a bit about the car.
