2000 Civic cranking noise when turning sharp or making U Turn?

any time you start to hear clicking noises as you turn this is the cv joints in your axles showing its age, the noise will actually get slowly worse over time, each time you turn right or left. Usually this is in a front engine front wheel drive car. By the time you start hearing the noise, there is already significant wear, this is entirely normal, under the hood there are two axles on long, on shorter, usually the longer one wears out first. One side may be worse than the other , but in the end you will need to replace both sides. A dealer will be more expensive, as they will use new cv axles. you can also buy a set already rebuilt, or one side or the other cheaper. Usually the rubber boot tears, and all the grease leaks out at some point. Its best to repair it before it breaks and does more expensive damage.
