Hi,
Whenever I make a sharp left corner, I hear a scratching of metal sound, the sharper the turn, the louder the noise. Does this mean the CV joint needs replacing?
Does it stop if you apply the breaks gently while turning? If so it could be coming from the pads or the discs, the CV Joints normally make a knocking noise when turning on full lock, you could turn the steering wheel on full lock at each side and look behind the wheels and see if the CV/Rubber Boot is burst or hanging off also leaking fluid.
This is what the CV Joint/Rubber Boot looks like..
