Understanding Your Ford Explorer’s Differential
What Is a Differential?
Your Ford Explorer’s differential is a crucial component of your vehicle’s drivetrain. It is responsible for transferring power from the engine to the wheels, allowing them to turn at different speeds. This is important because when you turn, the wheels on the outside of the turn need to travel a greater distance than the wheels on the inside of the turn. Without a differential, your wheels would be forced to turn at the same speed, which would cause your tires to scrub and wear out quickly.
Types of Differentials
There are several types of differentials, but the most common ones found in Ford Explorers are open differentials, limited-slip differentials, and electronically controlled differentials. An open differential is the most basic type and is found in most vehicles. A limited-slip differential (LSD) is designed to provide better traction by limiting the amount of slip between the wheels. An electronically controlled differential, also known as an active differential, uses sensors and a computer to adjust the amount of power sent to each wheel in real-time.
Function of Differential in Ford Explorer
In your Ford Explorer, the differential is located in the front or rear of the vehicle, depending on whether it is a front-wheel drive or all-wheel drive vehicle.
