I got an 05 screw 4x4, 8 inch rize, 2.5 TGC, 37x13.50x22 kuhmo. I got all my tires rebalanced, truck realligned, still no help. Its worse right around 30-35mph or on acceleration. While installing my train horns, I noticed that my rear shaft is out of the trans yoke about 3-3.5"... Could this cause the vibration??
