Looking for factory I.D. bore size for 57 rear axle bearing. After 64 years of hard driving I'm trying to verify if axle housing needs replaced or repaired.

The bearing bore is 1.378", but the outside of the bearing is 3.000" and the housing is about .003 larger. The biggest problem is the housings are out of round, causing a leak past the o-ring.
