knocking Noise From Dirvetrain
I have a 2016 2500 with the 68rfe trans. It has 14,000 miles on it. In the last couple of weeks I've experienced a knocking noise under acceleration from a stop.... not hard acceleration, just normal take off. It has happened four times now and each time was when the truck was cold and the outside temp was fairly cold as well ( 25-30 degrees). The knocking noise sounds as if it is in the drive-train .... It is definitely proportional to the rotation of the drive-train. It only does it when cold.
Anybody experience anything similar?
I should also mention that the truck is deleted and tuned with a 5" Turbo Back Flo-Pro Exhaust on it. I do not think it is a exhaust issue ... I have never beat on the truck at all .... haven't towed anything with it yet either.
