I have just had an interesting experience with my 1932 Wolseley Hornet Special. The Diff was showing signs of slackness, so I took it apart only to discover that everything inside was slack. All duly split-pinned, etc, by the previous owner, but now slack. So, new bearings all round, and rebuild with a few alternative bits and some new home-made castle nuts, but I could not get it together again. I had rebuilt the diff, crown-wheel, and pinion all together in the big casting, all carefully blued and adjusted, but no way was it going to go back into the axle. I admit I had found it all a bit awkward when I took it apart, but I put this down to the general looseness of everything. Nothing at all to do with my 75 years of inexperience. Comparing my bits with some 'useful spares' that came with the car, I noted that my big casting was steel, not light alloy, and the bearings were held with 7/16" studs instead of 3/8", but this was not causing the problem. It was the adjusting nuts each side of the diff bearings themselves, which are 2.05" hexagons, locked by a screw and notched washer, which could not be persuaded past the axle flange. The 'spare' version had castellated nuts and bent-up tab washers, so they were smaller, and would go in. I solved the problem by taking the nuts off the 7/16 studs, separating the diff from its housing, and fitting the diff assembly within the axle first, loosely held in position by engaging the half shafts. Then the big casting with pinion etc was fitted around it, the clamps repositioned and nuts etc, and I hoped not to disturb the adjustment (who knows?) and so far, all seems to be well. Is there something I need to know about these bits, I wonder – have I, for example, got a late diff in my early axle case? It certainly was not built like that by Wolseley, it would take too long.
Will it work OK with the diff assembly assembled within the axle – a process which makes it impossible to check properly that the clearances etc are OK? Time, as they say, will tell …
