How Diff Lock Works and When To Use It (UK Terminology, Land Rover)

This video instructs the viewer on how the standard CENTRE "diff lock" works in a permanent 4 wheel drive (4x4) vehicle, a Land Rover in this case, and gives an idea for how and when to use it. A Land Rover Discovery was the vehicle featured in the demonstrations, but this video applies to any 4x4 vehicle with a center diff lock. In summary, diff lock (whether it be the centre diff lock fitted as standard or front/rear aftermarket diff lock) is useful in slippery situations such as snow, ice and mud.
