A Look at Your Vehicle's Differential

At Porsche Monterey in Seaside, we keep our consumers informed about how their vehicles function. A differential is an important component that needs to be maintained for your vehicle to run smoothly.

A differential is a gearbox that can be found between the drive wheels of your vehicle. If you have a vehicle with four-wheel drive, it probably has a front and rear differential. The differential works with the transmission to move power from the engine to the axle of the wheels. A differential also helps your vehicle turn. The inside wheels need to turn at a slower rate than the outside wheels, and a differential uses gears to ensure that the wheels can move at different speeds.

A differential uses lubricating fluid to move heat from the gears, and it needs to be changed on a regular basis to prevent friction and grinding. If the lubricating fluid isn't changed, it could eventually lead to expensive repairs.
