Had the front wheel hubs replaced due to recall still have noise on 2009 Chrysler Town & Country

Mechanic said it's tire noise but it's so loud I turn the radio up to drown it out! I also have a slight vibration in the steering wheel that almost puts my hands to sleep

It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. Your Chrysler is too new to be giving these problems. Is there still warranty on this van, get the dealer to swop tires and rims from another van that doesn't have the noise/vibration and see if this proves the noise and vibration is tire/rim related. Try swopping the tires front to rear see if that changes the vibration or noise (provided rear tires are good).
Thanks, I'll try the tire swap 1st & see what happens.
