I have 99k on my 2011 Prius and my hub assemblies are still quiet, but I have read a few reports of hub replacement over on Priuschat.
Thanks for the tip on the runout. At this point we just have excessive road noise. If this bearing is gone, I am not sure why it failed early (in my opinion). We do have harsh road conditions here though, lots of salt and sand, so perhaps that damaged the seals. This is the first parts failure of any type we've had with this car though.
That is certainly a possibility - I can see that scenario.
