Stick with auto front hubs or replace with manual?

[MB]

FWIW: Our family wagon GU auto hubs were absolutely perfect for our past needs staying in cab without switching between school runs down the short highway and then feeding horses out in the wet paddocks on the way up to home. Smashed some of Tasmania’s iconic west coastal tracks too by locking them in for strength when needed. Their only downfall found that I never believed could but did oneday eventually happen was stubbornly continuing to run gear oil in its transfer case like its original era manuals stated. Auto transmission fluid is lighter and found needed in later manuals for GU auto hubs. The thicker transfer case gear oil of old will slightly rotate your front tailshaft just enough to spook the auto hubs into lock.

EDIT/Disclaimer: Please do check other threads I kindly learned off here too and your updated manuals beyond your 1999 edition

My first GQ had auto hubs, it did some wild stuff and I never had an issue with them.

FWIW: Have laid beside/roadside watching our old wagon GU and truly seen it happening/ front tailshaft twisting when in 2WD supposed to be auto-unlock times

I don't have any problem with the autos, but intend to replace with genuine manual hubs if I ever get a front Lokka.

This is literally how I found out the clicking/clacking noise from my drive train were the Auto hubs having trouble deciding to lock or unlock. And it happened to be in @mudski 's drive way many years ago after he pointed it out to me and then educated me to send that shitty auto plate into oblivion.
Fully manual FTW!

That’s the GO Hodgey Mate, although we did retain the OEM auto hubs needed after simply changing the transfer case to thinner fluid as mentioned worked for us, still going strong I hear

I haven't read the answers in the thread yet. but if they're nissan factory you can manualise them by taking out the autolock washer.
the hubs themselves are a lot stronger than most people need i wouldn't worry about overloading them unless you're really thrashing it.
