Update

Everything so far is (or has been) in place.  The replacement front stub axle assemblies are fitted.  The leaf springs are at last all painted and assembled. 
The new front axles were much more easily assembled than the earlier version, thanks to Steam Traction World for that improvement.
Both the front wheel inner bearings still have a small washer fitted alongside so that the wheels are further out and disks align neatly with the brake callipers; I spent several minutes re-checking the distances, and I think I have got the offset correct, using one 1.5 mm washer on each side. 
The disks still bind on the brake pads; I  am hoping that when hydraulic fluid is put in and maybe a short running-in period has elapsed then there will be sufficient play to allow the brake pads to withdraw and allow the wheels to rotate freely.  The front wheel toe-in will now have to be adjusted again.
I am trying to make sure that everything is painted before assembling any new kits.  I am having to remove some fitted parts in order to get access to some bare metal - the front wheels and leaf springs are currently removed for this purpose.  I am going round the current assembly to check for correct fitting and to ensure that bare metal is protected with paint, or WaxOyl chassis protection, or grease or other oily lubrication.  I am trying to imagine where moisture and dirt might get in when the car is in use.  I am considering using a small blob of silicone sealant (removable) to prevent dirt and moisture getting in to sensitive spots (The lower spring mountings are the only places I have found so far).
I have changed my painting materials to include a better primer, as I was having difficulty in applying paint reliably to shiny machined steel surfaces.
Current work in progress is to paint any remaining unprotected metal surfaces, to make good any damaged or sub-standard existing paintwork, and to check for adequate fitting and lubrication of parts. 
My inexperience with using paintbrushes means that I have some brush marks and paint sags to put right.  I have abrasive papers and a good paintbrush to help.  For improved cosmetic effects on the more visible areas, I am wondering about, in the future, using a fine abrasive followed by a coat of lacquer, as used on some modern cars with metallic finishes.  I shan't be applying any lines until much later.
Pictures will follow when I can photograph the Lykamobile with all parts fitted and no primer showing.  In the mean time we have had an inspection from the Assistant Chief Engineer.
