Alright I'm convinced that the sensation of the driveline is shifting under me slightly, when I stop and then let off the brake, is due to slip yoke binding.
It comes and goes and doesn't do it at all in neutral or on 4WD.
I have greased it.
Has anyone had any luck using anti-seize on them? Might be slicker, eh?

 

A dry binding slip yoke will sometimes produce a clunk that can be felt. I use a good quality bearing grease, but I've read that some guys use anti-seize with good results. If you've already cleaned and greased it I doubt if that's what you're hearing/feeling. It sounds more like bad engine and trans mounts.

 

I've thought about that but it just seems too young for bad mounts - no oil leaking on them to cause deterioration.
