be sure to check all your bushings...like the radius arm to frame,radius arm to axle,track bar...you could have one dry rotten and falling apart...causing some of this. also when was the last time you had a vibration free drive and then what changed when the vibration began? like was it there before or after the tire work was done...etc.
