Hey thanks for the info, guess I need to take it in for sum service and get it fixed.
You said you had a 2010 with almost 13k miles, I would definitely bring it in for service considering it should still be under warranty. If you're concerned about your aftermarket wheels contributing to the problem do you still have the stock ones to throw on? Might be worth putting the stocks on in case the dealer tries to BS you on warranting it.
In any case, nice looking truck, good luck, and welcome!
