Differential: What It Is and When to See a Mechanic
When you take a turn, not all your wheels spin at the same speed—and that’s where the differential comes in. Since it allows your drive wheels to rotate at different speeds while still receiving power, it plays a vital role in your vehicle’s handling. Whether you’re navigating the streets of Radcliff or leaving town to avoid the flooding, your differential helps keep every turn smooth and controlled.
At Meineke in Radcliff, our ASE-certified technicians provide differential inspections, fluid changes, and also repairs to keep your drivetrain working properly. So, in this post, the experts at Meineke explain what the differential is, how it works, why it matters, how to maintain it, and when to see a mechanic.
What Is a Differential and How Does It Work?
The differential is a gear assembly that splits engine torque between the wheels. Since the outside wheel travels farther than the inside wheel during a turn, the differential lets each wheel spin at its own speed. As your engine powers the drive shaft, the differential distributes that power to the wheels while allowing for speed differences between them.
Although vehicles have different configurations—front-wheel, rear-wheel, or all-wheel drive—they all use some form of a differential.
Why Is the Differential So Important?
Because it supports steering, traction, and control, your differential is essential to safe and smooth driving.
-
Improves turning stability – If the differential is working properly, then your car handles corners more easily.
-
Reduces tire wear – If each wheel spins at the correct speed, then tires wear evenly.
-
Delivers torque efficiently – If power is balanced, then your vehicle drives smoothly across all road types.
-
Protects other drivetrain components – If the gears inside the differential stay in good shape, then your transmission and axle last longer.
How to Maintain It
So, like any part of your vehicle, the differential needs care to stay reliable.
-
Change differential fluid as recommended – If the fluid gets dirty or breaks down, then gears may grind or overheat.
-
Inspect for leaks – If fluid seeps from the seals or housing, then it should be repaired to prevent damage.
-
Listen for unusual sounds while turning – If you hear whining, humming, or clunking, then the gears or bearings may be worn.
-
Schedule routine drivetrain inspections – If your vehicle is checked regularly, then early signs of wear can be caught in time.
-
Avoid rough driving or overloading – If your car carries too much weight or takes hard corners often, then it puts extra strain on it.
When to See a Mechanic in Radcliff

-
You feel shaking or vibrations while driving
