A Differential: An Important Component of Your Vehicle

Keeping your car well-maintained can extend its life and help it run smoothly. At KIA of Downtown LA, we try to keep our consumers informed about ways to keep their vehicles in optimal condition. One important component of your vehicle is a differential.

A differential is a gearbox that is located between the drive wheels. Vehicles that come with four-wheel drive have a front and rear differential. A differential works with the transmission to deliver power from the engine to the axle that turns the wheels, and it is also what enables your vehicle to turn. For a vehicle to turn, the inside wheels must turn slower than the outside wheels, and a differential uses gears to allow the wheels to turn at different speeds.

A differential uses lubricating fluid to transfer heat away from the gears. With normal wear, the lubricating fluid will break down, so it needs to be changed routinely. If it isn't changed, it can cause grinding and friction.
