Unless you have an awesome relationship with your Dealer, they will likely use any changes to the front suspension to nullify the warranty. I wouldn't blame them if they did- dealers have enough of a challenge finding and keeping good techs to work on stock vehicles, let alone chase issues that are possibly related to a/m parts. Not excusing it, but it is a direct result of the lack of people willing to work currently, and good techs are getting poached all the time.
One thing I just thought of, do you have spacers or rings between your Fuel wheels and the hubs? The correct concentric spacers help keep the wheels centered, and from moving around under load. Maybe check those?
