Um... are you sure they did an ACTUAL roadforce balance? I don't see how they could have if they didn't lift the car, since it sounds like the whole point of the exercise is repositioning the rubber so the highest point of the tire is precisely balanced against the highest point on the wheel: "You have to remove the wheel and tire from the vehicle to have it road force balanced. What the machine does is spin the wheel/tire slowly while pressing a roller against the tread with about 1400 pounds of force. It measures the "loaded runout" of the wheel/tire combination. Then it measures, using other rollers, the runout of the wheel where the bead seats. Then it instructs the user to mark the tire and the wheel, remove them from the machine, break the beads loose, rotate the tires on the wheel to match the marks, then re-inflate and re-mount the wheel/tire on the machine. Then it spins it again to measure the results, then spins it up so balance weights can be applied in the usual manner." (Source: Road Force Balancing - Toyota Tundra Forums : Tundra Solutions Forum)
You are misunderstanding I think or possibly I didn't splain thins right. Helix did my bushings only & no the bushings were not-road force balanced. My tire on the NOT N MG were.
