mines got bout 40 hours and around 700 miles and it just started on the front passenger corner is the only one that does it. after looking at it we came to the conclusion that it was the brakes cauise they were rubbing a little, anyhow rzrz are prone to braking hubs which can cause the cvs to go out if its not fixed. it will make that clicking noise and the way to check if the hubs are broke is jack it up and grab the tire by the top and bottom and see if it rocks and if it does you just solved your problem. hope i could be a help
