Whats up guys. I was just wondering how you test a possibly worn cv joint that causes vibration at high speed. I have replaced cv joints for this issue but it is almost always a guess. Usually I have checked to make sure everything is good and tight and say well it has to be the cv joint. This method has worked but I dread replacing an expensive cv like the ones on infinity's because they are so expensive. Even the cv's that I have confirmed were bad by replacing it I have found there is nothing obviously wrong with them. I like to hear some tricks that make me feel better about replacing an expensive axle shaft. Thanks for any tips you may have.
