Important Things to Know about All-Wheel Drive

You hear the term all-wheel drive in a many different commercials for vehicles. When you go to a Subaru dealer in Mokena, you will probably here the salesman say it more than once. They clearly think it is a selling point, but what does it really mean? And is it something that should sway your decision when you are purchasing a car?

What is All-Wheel Drive

In America, all-wheel drive means that all of your wheels are going to provide power. The drive train, which starts at your engine, goes to your transmission, and finally through drive shafts and differentials, spins your wheels. With all-wheel drive, all of your wheels are going to be connected to the drive train permanently. This can provide increased traction, and it will also handle better in adverse road conditions. You will also find a vehicle with all-wheel drive is going to be much less likely to become stuck on snow or ice.

Differentials

The differentials in an all-wheel drive vehicle are incredibly important. When you drive, not all of your wheels spin the same amount. This can most easily be seen if you make a turn in snow, and then go look at your tracks; they will follow different paths, and some are shorter than others. A differential is going to make sure that all of your wheels are free to turn more or less than their counterparts, and if they didn’t it would put great strain on your drive train. This stress is called driveline windup, and can cause major damage to your vehicle.

Now you know what a differential does, what is a locking differential? Well a locking differential is just a one that you can lock into place, making the wheels unable to turn independently. This is used in extremely poor road conditions, like what is found during off-roading. The lack of traction lets the wheels all turn at the same rate, preventing driveline windup.
