CLICKING NOISE IN TURNS indicates a worn or damaged outer joint, probably due to a cut or damaged boot.
CLUNK WHEN ACCELERATING FROM COAST OR DRIVE also indicates a worn or damaged joint.
SHUDDER OR VIBRATION, especially under acceleration could be from a worn or damaged outer joint or it could be from another source. If the CV-boots are in good condition and there is no obvious damage, look for a tire problem, an engine-related vibration or perhaps a damaged wheel with excessive run-out or out of balance.
VIBRATION AT HIGHWAY SPEEDS could be out of balance rear tires or wheels, out of round tires or wheels or a possible worn outer CV-joint binding or tight.
