I bought this truck and had a rough ride when I got it. I bought it stock with a bunch of grandpa stuff on it. I did a 2” spindle drop in front and 4” in the rear. Because of the ride quality before, we replaced the entire front end. The wheels are 285/45/22, which I know are big tires and have also fixed the rubbing issue. But on bigger bumps 40 mph or more. It feels like it wants to bounce of the road. Could it be the wheels or maybe body bushings…..????
