Front 4wd Hub keeps turning into lock position as I drive!

[Mattonpatrol]

Hey all on my 97 gu, The front right hub to lock my car in 4wd keeps turning into the lock position by it self as I'm driving on normal roads, I have to get out every 10km to turn in back into free because it keeps making a bad noise....... But when ingaged it into lock when I go 4wd it is completely fine..... What could this be?
Thanks all!!

Funky grease. Pull your hub off, give it a petrol bath, dry it out and regrease put it back together


Tap,tap,tapping in your head

could it be that something needs adjusting or may be worn out also?

I have read about the wrong oil in the transfer case making the front shaft turn enough to make the hubs lock in.

you could always stick a big zip tie around the front shaft and see what happens if it is spinning you'll hear it .

I've also read about the wrong oil bieng put in the transfer case ( by nissan I think ) which turns the shafts and cause noise . I would not think it would cause the hub to lock in so I would do what Stets said, but for both sides and check the wheel bearings while your there . Nothing more annoying than something not working right.

Also if your getting a bad noise with it in your wheel bearings are prop due for replacement.
