Thanks Diana.
Ive just looked through my phone at another photo of the stub axle. I hadn't realised the lip you mentioned when I had the bits in my hand but I can see now what you mean!! Fortunately its all gone together in the right order!!
As for the swivel housing (top) steering arm studs, 1 of the 4 on the top had a shoulder, the other 3 are all the same and parallel shafted.
Checking and setting the pre-load was a long and tiresome case of trial and error. Initially I put no shims on the bottom pin and then needed about 2.5mm of shims on the top - This gave me some indication of total shim depth, I then put half on the bottom pin and half under the steering arm and then put it back together and tried again. I measured the pre-load with some digital suitcase scales!!
Amazingly, once I got it very close to "specification", I could tell a difference between 1 thou. Now I have 1 or 2 thou more shims in the bottom than the top. This seems to allow the swivel oil seal to seal against the swivel.
I used a torque wrench on all 8 nuts each time (30Nm) to ensure I was comparing apples and apples on the scales. I could find no mention of this in workshop manual but it definitely makes setting the pre-load easier / quicker.
