Dealer recommended giving it more time and returning when it gets worse.
It looks like your symptoms were confirmed..
This is exactly what I identified to my Dealer, and they diagnosed it as the first signs of a tail shaft carrier bearing failure. It was replaced under extended warranty. My car had done 106,000 km at the time ( 66,000 miles). Started as a light shudder at highway speed.
Would be worthwhile for other to think of carrier bearing rather than being side tracked by "wheel balance".
