Can some one confirm this, on the 2014-2015 sierra, the back wheels doesn't line up with the fender evenly. On my 2015, the driver side wheels stuck in about half an inch. On the passenger side is about even with the front. I though it was just mine, but i got a loaner for the day and I check it out. It's the same thing. I'm not sure this is happening to every GM truck or not. It might be the cause of all the vibration that we're having. Please check. Thank you.
