I don't know about 1950 1ton rear axle bearings. But rwd cars and light trucks I have worked on the bearings had to be pressed on and off the axle.
Also why did he measure the bearings?
Micrometer is not zeroed perfect the readings will be off and you supplied them with the numbers off of the original bearings.
My knowledge is limited so I sure someone that knows his stuff will be posting here soon then you will get to the bottom of your problem. Jeffrey
