Hearing a "clattering" metallic sound when turning is the most typical sign of outer CV joint damage, especially when a distinct knocking noise is heard at the front wheels during full steering. This sound may disappear when driving straight.  Body or steering wheel shaking during acceleration usually indicates inner CV joint wear, and the shaking may lessen when lifting off the throttle.  Dust boot rupture and oil leakage are also critical warnings. If you inspect the front wheels and find the black rubber boot damaged with greasy residue being flung out, prompt action is necessary. Otherwise, sand and dirt entering will accelerate CV joint wear.  Notable jerking during acceleration or reverse, uneven tire wear, and steering wheel deviation are also chain reactions of CV joint failure.
