I purchased a set of RPG Offroad traction bars and had them installed at their shop. There is an obnoxious creaking noise coming from the rear every time I accelerate or decelerate. It has been two weeks and I though they might settle in and I also sprayed them with some silicone lube but nothing seems to work. I have left several phone messages and emails but they have ghosted me. Christian is the rep I was dealing with and I have to say I am totally disappointed in their customer service. FYI... You gotta earn that American Flag you are engraving on your product! Has anyone experienced this creaking noise and if so, did you resolve it. It is litterally driving me crazing.
