Just thinking out loud here, if the front and rear hubs are rotating as you say "400 revs and 10 revs" then your centre diff isn't working correctly. Maybe when it gets up to speed the little amount of LSD action that the centre diff still has working has brought the rears up to speed, but if the rear diff is the wrong ratio, then this is causing the skipping that you speak of??
I'm sure the wrong ratio rear diff would also quickly shag a centre diff, if it would drive at all. But once the centre diff is shagged, then it may drive ok, without you noticing because the centre diff is now open, and has no LSD.
Just ideas on what could be wrong.
Also I'm pretty sure you can swap gearbox internals, so the Gearbox code may say that it should be 4:11 but it might be something else.
Wavey.
