I just took mine to the dealer for this. I brought my iPad in and played the video another fella posted in the problem section.
I told him I think either something has come loose right where the steering wheel attaches to the column like a piece of plastic or something.
He took off the wheel and said that one of the screws had backed out and actually rubbed a groove into the base of the mounting surface of the wheel. He put locktite on the screws and re fastened. Thought problem was solved...
But as I pulled out of the parking space from the dealer it sure as shit was back...
Almost flipped out but just accepted the fact that this truck just has a clicking steering wheel and that's that.
I don't have the mental health left to pick apart this truck after trading in my brand new lemon Ram 1500 for this truck which is my dream truck. This truck has to many good things to make a big deal out of a click here or a rattle there.
But if you want to start your battle, I would start looking there.
