well i haven't done anything yet to really resolve the issue. since buying a 97 K2500 over a year and a half ago, the old truck has been parked in the garage relieved of daily driving service. it's just waiting for a complete build with a larger budget and more time.
but the problem has to be either a bad tire(s), out of round wheels (they're old aluminum wheels), or the fact that i have wheel spacers on the rear. all of which will be getting replaced with my choice of wheels and tires anyway. total build up, new rubber, new wheels, and the correct backspacing has to make the vibrations go away, right....?
