Hi Hugh
Presumably at least one hub has been run loose and/or lapped at some stage. If free of cracks it is extravagant to scrap an axle. A less worn or les lapped hub may suffice. Presumably some have reduced the width of the axle gear. Dunno how much considered prudent. Even if sealed bearings fitted still need to retain the large washer on the inner side of bearing.
I gather on Ford Model As it is customary to shim the taper. Cannot imagine success with the highly loaded Seven but has anyone tried? Would have to leave the pin out and constantly tighten.

I've tried other hubs that all reveal the same problem. I imagine that the half shaft has been lapped once too often. Not scrapping the axle, just replacing the offending half shaft.

The halfshaft inboard end can be modified on a lathe to lose a bit off the teeth without to much drama.

This evening I have been making a 1933 clutch cover plate lighter and smaller in diameter as well as reducing its thickness in the area where the springs sit and a reduction in thickness of the outer flange where it bolts to the flywheel.
The flywheel has already been reduced in diameter and had most of the outer ring milled off leaving six posts to bolt the cover plate onto it.
I might do a bit of undercutting on the outside of the posts.
The next part in line for lathe time is the pressure plate, this might not have a lot removed from it but there is scope to bevel the corners and remove a bit from the back where the springs seat.
Yesterday I self isolated under the car, adjusted the clutch on the crossshaft, greased the front suspension, and the steering box.
On Thursday I will grease the rear springs tweek the shocks and check the back axle oil level and have another play on the lathe.
