no manual hub locks to turn if that is what you meaning, auto hub lock, the hubs probably not locking though lol

Your best bet is to find a forum that covers your model. Auto locking hubs needing a clean and re-lube is a possibility.

Best plan is to replace the hubs with manual hubs. The standard Nissan auto hubs often will unlock in reverse. If you drive into a bog, have second thoughts and try to reverse out you will probably only have 2WD.
EDIT: I see AlliExpress has manual hubs for $32 US each.

Agree, auto hubs are annoying sometimes, as if memory is correct, they have to unlock then relock when you change from forwards to reverse? So potentially you have your rear wheels already spinning, before you get any drive from the front end. But another reason to prefer manual ones, is if you have them unlocked, you can use low range on sealed roads, without getting any windup, great for backing trailer's up steep drives etc.

Ta for the tips re manual hubs and Alibaba.
Any ideas what my current problem could be ? Or the straight out answer it's the auto hubs ?

I would check that the driveshaft to the front diff is actually rotating when 4WD is engaged, that would rule out any problem with the transfer case or linkages. Be aware that only one hub has to not engage to lose drive. Start by stripping, cleaning, inspecting and reassembling both hubs and go from there. If you are planning any serious off-roading, changing to manual hubs is highly recommended.
