AWD question

Can somebody explain to me why are we not suppouse to lock the 4x4 in our tribs on dry roads? I have not figured that out yey.<br><br>thanks, safe zooming these holidays.

The wheels on all vehicles are always turning at different speeds as we go around corners; the out side wheels must travel farther than the inside wheels. The differential in a rear wheel drive vehicle or the transaxle in a front wheel drive vehicle allows this to happen. The problem occurs on slippery roads when all the power starts to go to the tire with most slip. Just opposite of what we want. In 4x4s, the differentials lock up in order to transmit power more evenly to all the tires. The unequal wheel speed is not a problem in snow or mud since they can slip a bit. On dry pavement, the tires cannot slip at all and this may cause you to lose control of the vehicle. Full time or allwheel drive vehicle have differentials that compensate for the need of the tires to travel at different speeds.
