Helpful Expert Reply:

The seal you need is going to be more associated with the inner bearing and race. The outer bearing will help identify other parts but only if I have both bearing numbers. If both bearings are the same then the seal is # 34823 or for a pair use # RG06-010. You will need to pull the hub and get the inner bearing number as well to be sure.

These seals measure 1.249 inner diameter and 1.983 outer diameter.
