Mark Stopps, Operations manager at Experience the Country, explains a little about the centre differential, which is normally fitted to most 4x4 vehicles.
Why do we have a centre differential or "diff" and why lock it is the question asked on many BORDA training courses and to many people it is all a bit like black magic.
A centre differential is fitted to most four wheel drives vehicle with full time/permanent four wheel drive system to prevent transmission damage when turning on hard surfaces.
The centre differential allows the front and rear axles to travel different distances and speeds when the vehicle goes around a corner.
The down side of any differential is they will send the drive to the easiest wheel to turn so on a 4x4 vehicle with a centre differential it is possible for the vehicle`s drive to be sent to one wheel on one axle.
On most 4x4 vehicles this is overcome by being able to lock the centre differential thus dividing the drive equally to both axles therefore offering much improved traction.
