I have never actually tried that swap, but it's a definite maybe. The hub swap does work on 41-later cars. On 40-earlier, the spindle has a smaller diameter where the inner bearing cone fits.

On looking into the parts book, it turns out that the separator assembly and the cup are the same as 41-54. Only the cones are different. This should mean the cones or the complete bearing assemblies will swap to let you mount the later hubs on the early spindles.

However, this does not automatically get you out of the woods. The distance between the bearings could be different or the hub flange (where the drum seats) may be in a different axial location relative to the bearings. I think the only way to find out for certain would be to try it or talk with someone else who has tried it.

Good luck, and please let us know what you discover. Inquiring minds want to know!

Glad to oblige.

Ball bearings of the type used in GM front wheels have three components. The part you might think of as the inner race is the cone. The outer race is the cup. The balls, instead of being loose, are captured in a formed sheet metal part called a separator. On bearings of recent manufacture, the separator may be a molded plastic part rather than metal.

GM assigned a unique part no. to each component and you could buy them separately by their own number or all three together in one box as an assembly with a fourth number. In case you were going to ask if is ok to mix parts from different assemblies, I was wondering about that too. GM must have had their reasons for offering the individual parts separately, but I would expect used parts from different assemblies to develop differing wear patterns. For that reason, it probably isn't a good idea to mix new and used parts or used parts from different assemblies.
