Weird thing just happened, I closed my drivers side door and there was a ping ping noise like some piece of metal fell to the ground. I looked around and saw a sort of C clip lying there. I looked under the truck and saw a similar piece on one of the hinges of my side winder step, so I knew where to put it back (on the other one). Any body have this happen to them before? Should I worry? If I had not caught here at home and never knew it fell off I wonder what would be affected?
