My local dealer in Liverpool told me that my CV has failed. I knew that. As if I couldn't hear it. They replaced the CV boot in January 2008 while the car was still under warranty. They say that the CV joint can fail while no leak from the cv boot is apparent and therefore isn't linked to the CV boot. My car is no longer under warranty and therefore I am expected to pay. I told them about it during my last service in November 2009. But they didn't see anything at the time. Mind you even today, they still can't see any leaks with the CV boot. My question: Can a CV joint go faulty for another reason than the CV boot leaking though a loose band or a puncture?
