A car differential is a mechanical device found in the drivetrain, usually between the drive wheels (either at the front, rear, or both). Its main purpose is to allow the wheels to rotate at different speeds while still receiving power from the engine. Why is this needed? When a car turns, the wheels on the outside of the turn travel a longer distance than the wheels on the inside. If both wheels were forced to spin at the same speed (like with a solid axle and no differential), the tires would

➤ Differential Explained – Torque Distribution Mechanism The differential is a drivetrain component that allows the driven wheels of a vehicle to rotate at different speeds while transmitting engine torque. It is essential for smooth cornering, tire longevity, and drivetrain protection. ➤ Purpose of the Differential • To transmit engine torque to the drive wheels • To allow left and right wheels to rotate at different speeds • To reduce drivetrain stress during cornering • To maintain vehicle st
