A vehicle’s drivetrain is responsible for distributing the engine’s torque to the drive wheels through a complex maze of gears. Included in the drivetrain may be the differential, a transfer case (four- wheel and all-wheel-drive vehicles), and the transmission.
The differential is a special gear box located between the drive wheels of the vehicle and it serves 3 main purposes: to aim the power created by the motor at the wheels (torque), to act as a the final gear reduction by slowing the rotational speed of the transmission the last time before it reaches the wheels, and to disperse the power to the wheels while allowing them to rotate at different speeds, which is especially crucial when taking turns. Over time, the differential fluid used to lubricate the gears begins to break down and develop a gummy texture as a result of high operating temperatures, which prevents proper lubrication of the gears.
Periodically replacing the fluid will help prevent premature wear on the gears and may help in reducing wear on drive-wheel tires. Our differential service removes the old differential fluid and replaces it with new lubricating fluid in accordance with your vehicle manufacturer’s recommendations.
Transfer Case Service:
The transfer case is a specially designed gear box found in four-wheel and all-wheel-drive vehicles that splits the power between the front and rear axles. In all-wheel-drive vehicles, the transfer case serves to shift power between axles, depending on road traction conditions. Like the differential, the lubricating fluid in the transfer case can become contaminated and broken down over time, inhibiting its job of keeping the gears cooler and turning smoothly.
Periodically replacing the old fluid with new lubricating fluid helps prevent premature wear of the transfer case gears. Our transfer case service removes the old fluid and replaces it with new lubricating fluid in accordance with your vehicle manufacturer’s recommendations.
