Replacing Ford banjo rear end races

Banjo Races.  It's not what it sounds like!  The ends of the Ford banjo axle housings are actually wheel bearing races.  The roller bearings inside the rear brake drums roll on these races.  After 70 years of use sometimes these races get galled, especially on the bottom where most of the weight of the car does the most damage.

I had the races redone on my banjo rear end by a competent machine shop with a lathe with a big bed capable of handling these big axle housings.  They cut down the old races just enough to slip on new races that are heated and expanded and then pressed onto what's left of the old races.  When cooled, these form a tight fit.

Then of course, you need brand new roller bearings for the rear drums packed in grease and sealed.
