Thanks Jerry. When measuring for the id, would you measure the diameter of the surface the seal rides on or the diameter of the rubber portion of the seal?
Thanks for the numbers 52vff, however I believe we have two different axles. Based on the info I found on line the 455037 has an od of 5.506 and mine measures 4.8 od. Is yours a corporate 15,000 lb rear with vacuum operated two speed? If so, I may have incorrectly identified my rear.
