help 2wd sierra front stub or complete hub wanted doesn't matter what side

Are you sure it doesn't matter which side?

Apart from some very early ones they have opposite handed threads on each side (one side LH the other RH)
This to stop themselves unscrewing as you drive....

Don't recall having to undo the front hub nuts, but IIRC the rear ones on the drive shafts were as tight as hell and needed a hefty extension bar plus all my weight to undo. I know why they're tight, but they were a challenge to loosen that's for sure.

~350Nm rings a bell, but that might be wrong (its been a while)

I can only assume that ford changed them after they had some issues with earlier cars.... why else would you change to more expensive sided versions mid production?

Google suggests 250nm torque.

All I can recall is it was flippin tight!

Yes that's right F'Tight as my local garage tech called it
I believe I may have one of those nuts brand new and unused.
Laminated they are, so as to stay put, if i recall correctly.
If anybody has a need and wants to cover my costs, I look see.
