This is what the inside of the hub looks like.
I reckon you should pull it apart and have a look

hi guys. trying to diagnose my front wheel not locking properly problem. its locks in when ya turn the hub to lock bt if ya hold the tyre with your hands and turn it when its jacked up you can rotater the tyre with enogh force. at first i thought it was jst turning where ya lock the hubs in but after doing it again im not sure if it was maybe turning inside the diff. its got a lockright in there. cant check now really coz i have pulled the hub off down to where the axle is now exposed. just wanna know what part is responsible for the locking in |

The knob you turn pushes in a hub gear that locks on another gear that is on the end of the CV. Undo the little bolts and pull the front cap off, if its all in one piece i'd say you've done a CV/axle as per suggested in your last thread of the same thing. |

Doesn't a lockwrong only lock under acceleration, if that's the case turn you front drive shaft with the hubs locked and see what that does |

constantly locked , allowed to unlock easily without load (acceleration) |

not much with the wheels on the ground. and spin the wheels with them off. CompTruck wrote: if ya hold the tyre with your hands and turn it when its jacked up you can rotater the tyre with enogh force.
This is what i encountered with broken CV's. seems fine until a point, then slips as the CV expands. |

ok thanks guys. what will a broken cv look like when i pull it out? will it be snapped or will it just look normal? im unsure how they work |

the stub could be snapped. the axle could be snapped. both of which will be obvious. Otherwise the outer part will have a crack in it under inspection or the inner will have cracks in it, or chunks removed from it. |

ok i see how that works now. what is the next bit after the hub. that removes with 12mm (i think) bolts? does the hub lock into that bit and thats how the locking happens? |

the cv and axle are 2 seperate parts are they or does it all come out in one part? |

| Post subject: | Re: which part locks the axle on sierra front hubs |
That whole bit does it. Its called a manual locking hub. |

After removing the outer hub, you will have to remove a cir-clip from the axle. Then you can remove the 12mm bolts and then slide off the rest of the hub. 
Get a screw driver to bend back the locking tabs. Then you'll need a 50mm socket to remove the first nut. 
Behind that will be the locking washer thing-o. Followed by another 50mm nut.
