I have a 2008 duramax that has a 3 inch lift on it...since i have put the lift on it i have an annoying noise. When i am driving , usually in winds that are 30+, i have a slapping noise that comes usually from the pass side of my truck. Trying to find out if anyone else has had this issue and what they did to correct it. FYI my wife truck, a 2010 Denali has done the same thing since we added a leveling kit on it. I dont really wat to take the lifts off the trucks if I can find another way to fix this issue?? Any Ideas?
