Cv clunking noise

I have a new rzr xp 1000 with approx 150 miles on it. I am getting a loud clunking noise coming from my rear passenger side cv where it connects to the transmission. It only happens over whoops/ breaking bumps. I can wiggle the cv Up and down and it is a little loose. The drivers side is solid as a rock. There is no change in the performance of the rzr and the dealership stated this was normal. Does anyone else have this noise/ problem? Any info would be appreciated.
