As the rebuild on my IIa continues, regretably in hindsight, I flicked the original axles for a set of working properly SeriesIII axles. It hadn't really occured to me about what I had and what I may have got. This was kind of important when trying to buy things like brake parts as an example and led me on another long and winding journey to find out what the differences are between all of the axles and how to identify them.
This is what I've researched, worked out and cross checked. It took quite a while and I still don't have all of the answers - please let me know if there are any errors in it to make sure the info is accurate and usable. The things in bold I haven't been able to check and may not be correct, or there has been conflicting reports. Or please just confirm anything which is in bold or otherwise too! Thanks for any help.
Hopefully this also saves other people a lot of time trying to work all of this out, and money by not buying the wrong parts.
Note that the axles which are under your Landy, may not be the factory fitted axles by now.

Unless I am mistaken, all Series 3 had 16mm wheel studs, as did the very last of 2a.
And perhaps it would be an idea to add the warning that what you have on your vehicle may not be what it left the factory with.
Also, although not strictly axle, a good addition to this might be the differences in swivel damping and steering arms and a note about the change to tie rod ends.

Very sharp, you're right John! thanks very much for this, I was really hoping you'd see this. It seems the axles underwent a constant evolution in some respects.Originally Posted by JDNSW

I am pretty sure that the Series II and IIa had 9/16 BSF wheel studs. (except for the later metric ones)

Hello Slunnie,
Did you include variations in wheel nut size as well? Some Series IIAs had 15/16th Inch wheel nuts which were a different size to the Series III. An absence of wheel nuts could cause one some problems.
Kind regards

As Killer points out, Series 2 and most 2a had BSF thread wheel studs, not UNF. UNF was not used on any Landrover wheel studs. (I failed to spot that!)
From the first Landrovers to late in 2A production, all Landrovers had 9/16" BSF wheel studs, with double sided wheel nuts, which could be put on either way. Normally, there is no protruding thread when the nut is tight, protecting the thread on the stud from damage. The studs screw into the hub, and are retained by a groove on the inside of the hub flange, into which part of the stud is deformed, facilitated by a recess on the inner end of the stud. The nuts' hexagon is 9/16"BSF size. (BSF and BSW hexagons are specified by the bolt size, not the AF measurement, with BSF sizes one step smaller than BSW. Since 1939, most BSW thread bolts and nuts have had BSF hexagons)
In very late 2a production (and possibly not at all in Australian production) these wheel studs were replaced with 16mm pressed in studs, with 27mm one sided nuts and protruding thread when tight, the same as the Rangerover Classic, which had recently started production. Some vehicles were fitted with 15/16"BSF studs, but with single sided nuts that have 27mm hexagons, possibly to use existing axle stocks. These are quite rare, although the nuts are or were available and may well have been used as replacements on some vehicles as BSF/BSW tools became less common.
All Series 3 have the 16mm/27mm studs and nuts.
But a word of caution - Many Series 2/2a/3 Landrovers have had hubs or complete axle assemblies replaced by ones that are earlier or later. All parts are interchangeable, at least as subassemblies. So check what you actually have before ordering parts, and make sure the supplier knows the difference!

Thanks Killer, Lionel and John! Great info, thanks for picking that up too! Big oversight, great thing that you've seen it as I've picked up that error from somewhere. Incorrect info messes lots of things up and can get very expensive when purchasing. I'm really pleased for this info to be cleaned up.
I've lost editing rights on the original post, so I'll gather the corrections up a bit and see if a mod can edit it a little later.
Cheers

Let me know what you want done, Simon.
If you don't like trucks, stop buying stuff.
