I have had my 2014 Silverado now for 8 months & 13,000 miles, it still makes the creaking and popping noises on damp or rainy days. I had the dealership look at the truck three times now and they cannot determine the problem because they cannot duplicate the noise. I am at a loss on what it is , if I was to guess I would say it's the Rancho shocks. I am temtpted to replace the shocks but struggle with paying for shocks on a new truck. Has anybody figured out the problem completely? What are the thoughts of damp wet days effecting the truck and bringing on the noise?
