I have a 2015 Chevy Silverado 1500 LT 4x4. I have installed a 2 1/2” suspension lift with upgraded upper control arms. My truck will shake consistently at 60mph. I have replaced the upper control arms bushings, upper and lower ball joints, sway bar end link, wheel hubs, bought new tires and had them balanced as well as several alignments and it still shakes. I have also brought the truck to several mechanics with no luck of finding the issue. Any ideas on anything else I can check?
