My 2013 Jeep Grand Cherokee has a clunking sound somewhere in the drive line. Mostly from start but also during acceleration. Other times during shifting. Replaced the drive shaft to no improvement at all.

 

I am not very familiar with the newer models but why did you replace the drive shaft? It's the u-joints on either end that tend to make clunks etc when they wear out, but the drive shaft itself should last many years.

And if it also happens during acceleration, that makes me think transmission but again, not well versed in the newer models.
