I have a 02 ram std with a 2" leveling kit...Even before the level I have left-to-right (and obviously vice versa) vibrations over even the smoothest asphalt and amplified over potholes, ect. I bought the truck used with 17" rims and now have 20" rims (both factory). I have put new tires (balanced and aligned)and shocks on the truck, but still have it. Any ideas?
