I had the same issue couple weeks ago. Since my car is CPO'd, it was covered under the CPO warranty. I took it to the dealer and their master mechanic checked the car, and told me the "drift shaft u joint" needs to be replaced. It's not hurting the car in anyway as of what they stated, but it can in the long run. It's basically a piece of plastic. Got it replaced and now there is no issue. But it was going to be expensive if it wasn't covered (labor charges are insane!)
