An easy way to see if it's the u-joint is to grab the driveshaft and try to twist it back and forth. If there's play in the u-joint it might be bad. Your car is brand new, so unless it came from the factory with a defect, this probably isn't the case. Note: don't do this while it's spinning.

More likely, it's the diff flexing on its bushings, which are pretty soft and allow for a lot of movement. Whiteline makes inserts that take some of that compliance out, at the cost of a little more NVH.

Even more likely, it's the gear teeth in the transmission getting to know each other.
