One of the distinguishing features of cars is their ability to drive with two or four wheels. This distinction relates to the power your engine provides each wheel and how it affects your driving performance. In a four-wheel-drive car, you need a transfer case to move the power from the front wheels to the back ones. As you can imagine, this piece of equipment is vital to one of the most basic functions of your automobile. If the transfer case falls into disrepair, you could lose your capacity for a four-wheel drive. To avoid this problem, follow these tips for caring for your vehicle’s transfer case.
