What Is a Differential in a Vehicle? A differential is a critical component of your vehicle’s drivetrain. It allows the left and right wheels to rotate at different speeds, which is essential when making turns. Without a properly functioning differential, turning your vehicle smoothly would be nearly impossible — and could cause excessive tire wear or damage to your drivetrain.

Why Do Wheels Need to Turn at Different Speeds? When your vehicle makes a turn, the outside wheel travels a longer path than the inside wheel. To compensate for this, the differential ensures that each wheel spins at the appropriate speed while still receiving power from the engine.

Where Is the Differential Located? The differential is typically located between the two wheels it controls and is connected to each wheel by an axle shaft. The location varies based on your vehicle’s drivetrain.

Have You Ever Changed Your Vehicle’s Differential Fluid? If not, you could be risking premature wear and tear on one of your vehicle’s most important drivetrain components. Differential fluid, also known as gear oil, provides essential lubrication to the gears, bearings, shafts, and other internal components inside the differential.

Over time, heat, pressure, and friction break down the protective additives in the fluid. Additionally, metal particles and clutch material from normal wear can contaminate the fluid — and in some cases, moisture or water intrusion can further damage internal parts like bearings and gears.

Why Is a Differential Fluid Change Important?

• Protect gears and bearings from excess friction
• Remove harmful contaminants from the system
• Prevent overheating and fluid breakdown
• Extend the life of your differential
• Improve overall drivetrain performance

At Sergeant Clutch Certified Auto Repair Shop, we offer a complete Differential Fluid Change Service designed to extend the lifespan of your vehicle’s differential. Our expert auto technicians will:

• Drain the old differential fluid completely
• Inspect for signs of contamination or metal shavings
• Refill with high-quality synthetic gear oil that meets or exceeds manufacturer specifications
• Ensure your vehicle is road-ready and protected for the long haul

Whether you drive a car, truck, SUV, or van — front-wheel, rear-wheel, or all-wheel drive — regular differential fluid service is essential to keeping your drivetrain healthy. Located in San Antonio, TX? Call or stop by today for a differential inspection or fluid change!
