Who said ball type wheelbearings have less friction?

I seriously doubt it!

I think so, it rings a bell anyway,

didnt they make the shoulder thicker due to the material change.

They made it thicker to remove the preload from the bearings so the spacer is then redundant effectively. This can be achieved by just removing the spacer from an iron hub.
If you use a thicker spacer with a standard shoulder it would have to be the exact size so you dont get any movement in the bearing. KAD just nip up the hub nut

I seriously doubt it!

That all sounds completely wrong to me

I know on most Aston Martins, they have taper bearings with no spacer, the nut is just nipped up on them

I seriously doubt it!

just to clear something up,are we now talking about rear or front hubs,

Personally the spacer is doing an important job. The spacer is setting the preload, then it allows you to tighten the nut sufficently so that it does not come loose during use. yes the split pin is there to stop it but it isnt that strong. Due to it being the driven wheels the forces are diffferent compared to say the aston front bearing. When I was running Drum CVs I had an issue where the hub nut was loosing torque, due to me stretching the cv under power. During my diagnostic to what was happening I had a cv joint strech loosing torque then started to work against the split pin and destroyed it. the only reason I found it before I had a major problem was because I was checking hub nut torque/split pin condition regularly, if it went undetected the results would not be worth thinking about.

Also a note on grease, think of grease as oil contained in like a sponge, when it warms up the oil is released, when it cools it gets absorbed by the sponge part of the grease. different greases have different operating temps and therefore some work best warmed up.

On an item at work we can see the differences in this drag. It is built with some special high temp grease that is ptfe based, and if we run the test item too cold the drag from the grease is noticable compared to the normal operating temp.
