The cush hub (sprocket carrier) bearing leads a tough life. This is especially true if your cush rubbers get old and soft. They can allow the chain to pull the cush hub sideways putting a twisting load on the bearing. If there's any question about the condition of your bearing replace it now with this double sealed bearing and quality seal.
