Fixing GQ/GU auto hubs

[dalmatia]

hi everybody,

i was searching for some infos about nissan patrol's hubs and i found this forum
two day ago i heard clicking noise and i didn't know what's happening. later i realized that auto/lock screw is very easy to move left or right. also when i stop the car i can hear "unlocking" noise. if i understood well, i would need to remove the auto mecanism and refit the hub. how safe is to drive like that? i have already ordered a new hub (approx 450 euro).

regards from croatia

Hi Dalmatia,

I have a GU Patrol and had the same problem. I pulled the Auto Hubs apart and removed the auto locking mechanism completely. The hubs now perform just like manual locking hubs. It's fine to drive now and no more problems.

You can use GQ hubs on a GU too, they are virtually the same. I have heard the GQ hubs are a bit stronger but I'm not sure if there's any truth to that.

Cheers

Any idea how it comes they start rattling? Someone told me too much grease inside...

Hi Just to let you know

Hall4x4 are now stocking replacement hubs that are new, they are identical to the genuine hubs, however don't come genuine packaging.

Dont pay high prices for second hand hubs, upgrade to new Free Hubs which are much stronger.

Hall 4x4 can post anywhere in australia,

details of the hubs are here..

Tony am I correct in saying that if you remove the auto mechanism from the hubs,
It will be permanatley locked in all wheel drive until you select 4wd??????????

No, after removing the auto mechanism auto becomes unlocked (free) and locked is still locked.

I was having clicking and clunking issues with the Auto hubs.
Changed to a set of Manual AVM hubs and no more clicking and clunking......so far!

With the Auto lokka in the front, also gives a bit of peace of mind that it is unlocked when it is supposed to.

I have read a number of threads on forums about these problems and they seem to be very common with the GU auto hubs.

***NOTE, since posting this I have found that on some GQ's the auto locking mechanism is mounted on the end of the axle instead of on the hub as shown above. Removing the mechanism may require the fitting of a small spacer to limit axle movement.

and if you remove the inner of the auto mechanism, the outer makes the perfect spacer.

Hey. In need of help. My gq auto hubs were the same as pic above with auto mechanism on the axle. I removed the auto mechanism. Took both sides of and put the circlip back on to hold the axles out still. Now my problem is that my hubs don't lock at all. Is this because I removed both sides of the auto mechanism? Do I need to put one of them back on? And which part should be put back on if this is the case? I've got a 4wd trip on Sunday and only just found out today that they are not locking in. Help will be very much appreciated.

Also I'm able to turn the locking key both ways and keep turning it as much as I like.
