The 72 axle has wider brakes than the 50 does. Is it possible to swap rear hubs on these axles? I would also have to swap backing plates and the entire brake assembly.
The outer bearing # is B11630 and the inner bearing # is O11784 on the 72 axle.
I have not torn into the 50 axle yet but I have an interchange manual that says the outer bearing # should be B11630 and the inner # should be D11786.
The outer bearing # matches.
Or, should I just weld spring mounts on the 72 axle and use the entire axle?
Thanks | | |

You should find the newer housing is 3.5 inches longer. I have thought about the swap, but haven't been able to justify the expense of narrowing the housing.

I just measured a rear axle cut from a 50 Chevy 3/4 ton panel. The full floater axle measured 63 inches between the two wheel mounting flanges.Seems a little wide? | | | | | Joined: Feb 2001 Posts: 1,897 Member | | Member Joined: Feb 2001 Posts: 1,897 | Axle splines the same?????

Later in the spring (when and if the snow melts) I will try the hub swap. If the hub works, I might be able to use the original axles. I'll post my results. | | | | | Joined: Feb 2001 Posts: 1,897 Member | | Member Joined: Feb 2001 Posts: 1,897 | Make sure you guys are checking the measurement on the axle shafts left-to-left,and right-to-right
One side is 31&1/2 inches.One is 37&1/2 inches.
