When a car makes a left turn, the interior-facing wheels (on the left side) naturally turn slower than the exterior-facing wheels (on the right side) because the exterior-facing wheels have to travel farther to get the car around the corner. For this reason, the wheels of a car need to be able to revolve independently and at varying speeds to prevent slipping and to keep the car moving with power around corners.
A car’s differential is a mechanical set of simple planetary gears that allows wheels to spin at independent speeds, and to be independently powered by the engine through the car’s drivetrain.
The differential, generally known as the gearbox, contains gears that associate your vehicle's two axles. It comprises a drive pinion and ring gear to allow the rotation of two shafts at various speeds. Differential gears are a part of the rear axle assembly. They are utilized to change over the long way flow of power from the engine through the clutches, transmissions, and propeller shafts into a right-point direction. This change permits the engine capacity to turn the back wheels and allows the wheels to move at various velocities, as when turning a corner.
The differential gears are submersed in gear oil to protect the moving metal surfaces from friction and wear. Typical driving subjects this fluid to high temperatures which inevitably separates the fluid. The outcome is metal to metal contact and extremely high heat that in the end keeps gears from turning the vehicle's wheels.

How Often Should I Go In for Differential Service?
In this view, since your vehicle cannot function without a differential, we highly recommend getting your differential inspected, and the differential fluid changed, as a part of your regular vehicle maintenance routine. How frequently differential service is required will change from vehicle to vehicle based on the vehicle made, model and mileage. A&A Quick Lube offers a drain and refills service which includes: draining old differential fluid and replacing it with the manufacture's recommended gear oil.
