How do they work?
By using centrifugal force the free moving weights (durametal and synthetic fluid) sealed in the balancer automatically distributes to exactly where needed, placing the assembly in equilibrium or perfect balance. When a sprung assembly is out of balance, deflection is caused via the springs or tire sidewalls. These free moving weights sense this deflection and move opposite the heavy points to balance the entire assembly, wheels, tires, drums, hubs, even mud, snow or ice stuck to the wheels.
This problem can be found by inspecting the area where the wheel and tire meet. A guide rib or circumference ring is molded into the sidewall of the tire. Measure the distance from the wheel to the guide rib (approx. ½ inch depending on tire brand), at the top, bottom and both sides, a variance in this distance indicates a mis-mount. A mis-mounted tire will roll out of round. This leads to erratic tire wear and vibration, regardless of how well it is balanced. Reseating the bead properly corrects the problem.
Simply remove the wheel, use the bolt holes as guides and reinstall the wheel. Steer axle balancers mount between the hub and wheel, while balancers for the duals mount between the dual wheels.
