If the suspension and steering components are in good condition, then the 
next things to re-check are
Wheel and tire balance, preferably on a machine that simulates road force
Inspection of the tires for internal damage or defects
Wheel/hub interface
Wheel lateral and radial runout as measured by a dial indicator
Tire lateral and radial runout as measured by a dial indicator
