Has anyone had this done?
Usually, on vehicle balancing methods, use a single counter weight.
Each weight, as per Snap-on, namely the heavy spot and then the counter weight, affects 150 degrees of the circle.
That leaves 2 areas of 30 degree, unbalanced, if you wish. Therefore that type balancing has a short life of just a very few thousands of miles, perhaps 3 to 4 thousand at best.
When the running gear is properly balanced, a counter weight is placed 120 degrees away from the heavy spot. That then gives the circle overlapping balancing. That type, normally lasts 10,000 miles. I have used that method for over 40 years.
Or, a person can install the Centramatics, as an example, and be through with the question of balancing the running gear, as they continuously adjust for the tire wear as well. This is assuming, that the hub and drum assembly, is not "pounds" out of balance. Many of the old 3 piece hub and drum assemblies, were horribly out of balance.
That was somewhat corrected when the 2 piece hub and drums, became available many years ago. Today, hub and drums are "unicast" and are one piece, making it much easier to balance, and to keep in balance with devices such as the Centramatics.
