What Is the Drivetrain and Why Is It So Important?
Your vehicle’s drivetrain is a complex system that delivers engine power to the wheels. It includes parts like the transmission, drive shaft, differential, CV axles, and U-joints. Together, these components work in harmony to maintain smooth acceleration, precise turning, and overall drivability.
The drivetrain includes:
-
Transmission: Converts engine power into torque.
-
Drive Shaft: Transfers torque from the transmission to the differential.
-
Differential: Distributes torque to the wheels, allowing them to rotate at different speeds when turning.
-
Axles: Deliver torque from the differential to the wheels.
-
CV and U-Joints: Provide flexibility and motion between moving parts.
If any one of these parts begins to fail, you’ll likely notice a difference in how your vehicle drives. That’s why timely repairs and Fluid Service are critical to preserving performance and safety.

The Importance of Fluid Service in Drivetrain Health
Your drivetrain and differential systems rely on specialty lubricants to reduce friction, cool down components, and prevent wear. Over time, these fluids break down or become contaminated, leading to increased heat, metal-on-metal contact, and premature part failure. Routine Fluid Service is one of the most effective ways to extend the life of your drivetrain and avoid costly repairs.
We offer fluid services for:
-
Differential gear oil
-
Transmission fluid
-
Transfer case fluid
-
CV joint grease
-
Axle and hub lubrication
Our team uses top-tier fluids that meet or exceed OEM standards, and we’ll recommend service intervals based on your specific vehicle and driving conditions.
