Final Drive Assembly: Components, Functions, and Maintenance

The final drive, also known as the differential assembly, is a crucial component of a car's drivetrain system, responsible for transmitting power from the differential to the wheels while allowing them to rotate at different speeds. Explore OEM final drive parts in our catalog.

Components of the Final Drive Assembly

Key parts include:

• Ring Gear: Transfers power from the differential to the side gears connected to the wheels.
• Pinion Gear: Works with the ring gear to transfer power to the wheels.
• Differential Case: Houses the ring and pinion gears.
• Side Gears: Connected to the wheels, allowing for variations in wheel speed during turns.

Functions of the Final Drive Assembly

The final drive assembly optimizes traction, stability, and steering control, especially in rear-wheel or all-wheel drive vehicles, by allowing for variations in wheel speed during turns and distributing power effectively.

Maintenance of the Final Drive Assembly

Proper lubrication and adjustment are essential for optimal drivetrain performance and longevity. Signs of a malfunctioning final drive include whining or grinding noises during acceleration or deceleration, difficulty turning or steering, or uneven tire wear. Regular inspection and servicing ensure continued traction and stability.
