My diff lock often doesn't engage when the gearbox is cold, but completely fine when warmed up.
There's the warning label on the seatbox and in the manual that you should engage it before lifting, but if I properly chock the wheels on the other axle would there be a problem if it was not engaged? On hard level ground surely things would not move much. If I come out to a flat tire one morning I can't really drive it around to warm up before changing the wheel... |

That's great - thank you for clarifying!
I'll definitely try your tip for warming up the box. |

Really? As far as I'm aware the handbrake acts on all 4 wheel simultaneously, so will still hold the fronts when the back is in the air? An engine to TDi for! "Land Rover- Proudly turning drivers into mechanics since 1948" |

With a back wheel in the air and the center diff unlocked it will roll!

Same principal if you have 1 wheel on 1 axle spinning in the mud, you stop, lock the center diff and you transfer 50% of the torque to each axle so you can get drive again to the axle with grip.
hand brake only locks the back wheels as its only on the rear side of the center diff. Keith |

But not if it's in gear. |

Depends on the slope or how tight the wheel nuts are!
