ABSTRACT:
A method of balancing and aligning wheels on trucks which includes the steps of removing the bearing slack from the truck wheels by tightening the bearings; trimming or "trueing" the tires of the elevated drive tandem to the center of each axle as the center of the respective tire rotational circle; marking the axle hub to insure re-mounting of the tires in the same position on the axle hub; utilizing a strobe light and vibration sensor to detect weight imbalances in each set of trimmed wheels when the wheels are spun at high speed as the frame of the truck is jacked, and balancing each set of the trimmed wheels by adding weight to the areas on the wheel rim where balancing weight is needed; setting or adjusting the wheel and axle alignment using laser beam equipment and wheel alignment racks fitted with levels; and providing balanced brake drums in the wheels, if necessary.
