I have a 2006 f350 ext. cab long bed zf6 manual trans. With 35's and a 3 front Leveling kit...when I'm reversing and turn to the left it does like a true rubbing sound underneath or behind me outside the truck And when driving if I turn right that's the only time it does it at low speeds and it recently started vibrating the body of the truck while driving around 40-45 mph and at 60-70mph had tires rebalanced and rotated a a still does it! What's my problem? How would I got about fixing it? Thankyou in advance!
