Planet 4x4

Tip:

Differences Between 4x4 and 2WD The first difference you will notice is that the 4WD has far greater ground clearance than a 2WD. Some 4WD's have what are called free wheeling hubs fitted to the centre of the front wheels. These hubs can be either manual, where there is a knob to be turned, automatic, where once in 4WD the hubs lock automatically or a combination of both. The idea of free wheeling hubs is to disconnect the front diff and axles from the wheel, so when traveling on highway, the vehicle doesn't have to use extra power turning these when they are not wanted.
