I been driving my 02 civic for a little over a week now since I bought it and I been hearing a knocking sound mainly while turning left. It also happens while changing gear to reverse n drive. I don't think it is the Cv joint since its just a single knock. Its coming from the front passenger side of my car. Any ideas?? I'm assuming its the axle but not to sure. I was going to take it to a mechanic for diagnostic but the price was outrages. I don't have my tools anymore to check myself as well so I just need some logical answers before spending more money than I can afford.
