2016 3500 dually. I do tow 12-15k# from time to time (boat or tractor). 65k miles on here and the steering wheel noticeably shakes when I hit the brakes firmly. When I let up and hit them easier, less shaking. I’m figuring warped rotors. Rather than give money to the dealer, or even try to have the rotors turned, I might as well replace the rotors and pads. Any suggestions on OEM vs aftermarket?
