    First, check to see if the outer ring has slipped with respect to the hub. For 1955-68 balancers, the keyway in the hub should align with the timing mark on the outer ring. If it's displaced, the balancer definitely needs to be rebuilt or replaced.

    Next, inspect the exposed rubber to see if it's badly cracked. If it is, that might be a clue that the balancer needs to be rebuilt. However, it could still be OK because the outer portion of the elastomer has no functionality and the inner portion, the important part, could be OK. Nevertheless, if it appears deteriorated, it might be time to rebuild or replace.

    I do not know of a rebuilding source on the east coast.

      Also check for axial and radial runout. Watching it at slow idle with a good shop light is a quick visual way to do this.
