Signs of a faulty CV joint are CLICKS coming from the front of the vehicle while performing sharp turns. To really put this to the test, you should drive backwards in tight circles, if you hear any clicking you have a bad CV somewhere you should be able to tell which side of the car it is coming from. Try not to drive very far on a bad CV joint, because you could become stuck out in the middle of nowhere!
