Outer Limits 4x4 Board

Just recently as in the past couple of days my auto hubs on my GQ shorty have developed the habit of clicking in in a half arsed way at about 80km/h. I'll be driving along and then they just start whirring, so I pull over put it into 4wd, drive forward and bit and back into 2wd and then off again and its usually worked. If it didnt then I repeat the process.
Now before anyone says just buy some manual hubs, it was already on the agenda but this is a problem in the mean time. Is there a spring or anything in the auto hubs that would slacken over time therefore allowing the above to happen???? If so, what can I do about it?

Have you changed your transfer case oil recently? the problems we had at nissan when i was there was caused by too thick transfer oil. It should have nissan matic D fluid in it. The thick oil causes the shaft to turn at high speeds partially engaging the hubs.
Hope this sorts the prob for you.

I wouldn't pull the auto hub appart as they can be terrible things to reassemble

I hate auto hubs.... give me manuals anyday

Had the same trouble this week. I pulled teh auto hubs apart and couldn't fiind anything wrong. I just locked both sides for the time being.
Went down to the wreckers and bought nissan manual hubs for $100 each!!

Auto hubs are crap (but handy at times)

its amazing what a clean and regrease does, they just need some attention from time to time especially if you have/had wheel bearing problems

CHECK THE OILS I SAY!!!! AGAIN !!! Put trans fluid in your transfer .

I will change my oils like you said but my left side hub was starting to grind!!!

GRIND OR CLICKING NOISE ? ? ?

When i jacked up the wheel and spun the tyre it was grinding like small stones werte in there!! I pulled it apart and it all seemed fine....i cleaned it up, regreased and bang it locked in again while driving!!

Any play in your wheel bearings??

Nope
