I use to think that the only way to tell waht was inside the axle was to muddle through all that old grease and lub.... but now I know better.

On any axle..... Furd or Chev....pop off the 3 screws to the hub cap and clean out the ned of the axle shaft.....

The elusive Type "B" has a larger machined hole in the center. Wheras the type "A" has a machined recess that held the part in the lathe when machined... the type "B" has a machined hoel all the way down the axle shaft..... the visible opening is larger and if you feel around the hole you will find a recessed set screw about an inch inside.... you have to remove the cotter pin to see the depth of the hole....
