Patrol 2001 GU Auto front hubs

Craig
I'm not sure what the problem is, but a word of advice be careful when using Auto the hubs will lock in but the moment you reverse they will unlock until the wheel has completed 1rev before re-engaging. When going out 4WDing I always manually lock in my hubs then its just a matter of selecting HorL4WD or 2WD when required
Lets know what the prob was

Craig, before you remove the hubs they must be in the lock position for them to come off in one piece.

Hi Craig,
I have found by experiance that if one goes into 4wd for some serious work then it pays to lock the hubs in manually this stops the unlocking and locking when rocking back and forth therefore stopping any ratcheting that sometimes can happen.
Like the others have said it is relativly easy to undo the 6 allen key bolts and service this area as well as adjust the wheel bearings if need be. As for the hubs needing to be in the locked position I do not know but I think mine were in the unlocked / Auto mode when i removed them. They are not the same as the standard free wheeling hubs.

Thanks for your advice guys. This afternoon I had a go and took one off while in the manually locked position, it came off no worries, so tried the other side in the auto position and that came off just as easy.

I found a little philips head screw had come out on the RH side, there is a locking plate of some sort on the stub with two philips head screws holding it in place. One of these was out. I hope this was the problem from last w/e.

I packed heaps of grease inside each hub and bolted them back on. I will have to wait until next time off road to see if this fixed my problem.

Thanks Craig

Hey Govo and Get1
I know from experience that if hubs are locked in in auto Hi or low and you reverse for 1wheel rev you will hear a distinct click as they unlock go back another rev and they will lock back in again.
BTW a mate of mine whos has a GU got caught by this when he first tried his truck on the sand at Lancelin. He was in soft sand, auto lock engaged got bogged -yes tyre pressures were reduced, while rocking back and forth was OK until front wheels turned 1 rev and CLICK, 2wd only.
You can try this on the road Stop wind window down engage auto 4wd and take off slowly, you should hear a distinct click as auto 4wd engages, stop reverse past 1wheel rev and you will hear a distinct click 4wd has disengaged(dash board indicatormay still be on but you are in 2wd) keep reversing and you will hear another click as 4wd re-engages.
