It is unlikely that you have frontend wear on such a new vehicle, but go to a
different shop and have them check everything and align it again. I have 22K on my '04 Colorado and just rotated the tires last week for the first time. They started to have a slight cup on the inside of the front tires, and on some roads I could hear a little noise from the cups. It looks like the Generals will go at least 45k. I am not letting anyone with a wrench close to the frontend on my truck.
