Hub Locks On or Off ..... all time

[the evil twin]

All the GUs I've come across must be different to all yours. My GU doesn't have an "unlock" position. The two positions on mine are "lock" and "auto". I leave mine in "auto" and when off road in 4WD it locks automatically (funny enough) whenever required.

Whatever, but I can't actually "unlock" mine.

Your correct about the GU's but he has a GQ, Cobber

Leaving the GQ manual front Hubs or GU aftermarket/mod'd Hubs locked is no biggee, just increases the fuel use a tad and also a taddy bit of extra wear on tyres.
Might get a bit of extra NVH at higher speeds on bitumen as well.

It is a very good idea to 'LOCK' the GU auto hubs if you are doing serious wheeling (as per the owners manual).
When left in 'AUTO' the Auto hubs can get damaged in certain 4WD situations if you don't which is why some (not all) people who don't understand them will bag them out.

With my other "part time " 4x4 I would lock the hubs in every so often just to get
the oil flowing. I would also put the little stick into Hi-4 for a short period as well.
Never do them both together, If you find you cant shift back into Hi-2 just reverse for about 10-15 mtr
to "un-wind" the drive line.

I think he said he has a GQ, so manual hubs. BTW love my auto hubs on my GU.

Whoops - I did miss that, I thought it was a GU. The only thing I have found with leaving the hubs in "auto" is when I take it out of 4WD, I always reverse a few meters to allow them to unlock properly. In all the years I have had the GU (2000 model) I have never had a problem with the hubs. I have serviced them a few times to make sure the grease is still good - but they always automatically lock and unlock.

i have noticed when the hubs are locked the steering is heavier. running around on dirt i would leave em locked but if i was going any distance on the black stuff i unlock em

Bummer Nissan did not go for the center-diff with locking option. That would have made it the absolute 4WD - can n't count the number of times I had to lock the center-diff of my LandRover County on our previous , very muddy , property.

There is no need for a center diff lock. It is locked.. direct drive when 4wd is selected..
The only slip point is the open front diff.. And LSD rear but they are the best lsd around..
So a simple front lokka and you'll have basically locked 4wd..
Only step better is twin locked diffs..

I keep them locked in the wintertime. In summertime or when driving on dry roads i unlock them to save fuel.
Remember to lock them for some kilometers once a month keep them lubricated.

Speaking to people over the years I must say that I am surprised at how many don't really understand this fact about part time 4wds. A lot of people think the Patrol is a less capable vehicle for not having one. It is a difficult thing to explain when all the components are sealed and out off sight.

Yea it seems a simple concept ey. But once someone gets a mind set it's sometimes hard to change
