Understanding the Drivetrain & Differential
Your drivetrain is the system that transfers power from your engine to the wheels. It includes the transmission, drive shaft, axles, differential, and other related parts. The differential allows your wheels to spin at different speeds during turns, making handling smoother and more responsive.
When these systems aren’t functioning properly, it puts a strain on your engine, reduces performance, and can even lead to major damage if ignored.
Key components of your drivetrain:
-
Transmission – Adjusts engine output to deliver appropriate torque
-
Drive Shaft – Transfers power from the transmission to the differential
-
Differential – Splits torque between the wheels while allowing them to rotate at different speeds
-
Axles – Deliver power from the differential to the wheels
-
U-joints/CV joints – Provide flexibility and movement while transmitting torque
When any part of this system wears out, fails, or leaks fluid, your vehicle’s performance suffers.
Signs You Need Drivetrain or Differential Service
Since the drivetrain is made up of several parts working together, issues can present in a variety of ways. Early detection is key to preventing more costly repairs.
Common symptoms to look out for:
-
Clunking or grinding noises when accelerating or turning
-
Vibrations while driving, especially at higher speeds
-
Difficulty turning or a dragging feeling
-
Leaking gear oil or differential fluid
-
Whining sounds coming from underneath the vehicle
-
Trouble shifting gears (for automatic and manual)
-
Vehicle feels sluggish or lacks power
If you’re experiencing any of these problems, bring your vehicle to Fenski Automotive Center for a full diagnosis. We’ll get to the root of the issue and offer a clear, honest solution.

Importance of Routine Fluid Service
One of the easiest ways to protect your drivetrain and differential is by keeping up with fluid service. Just like engine oil, gear oil and differential fluids break down over time and lose their protective qualities. Dirty or low fluid levels can cause friction, overheating, and eventually part failure.
Benefits of routine fluid service:
-
Reduces heat and friction in gears
-
Protects internal components from wear
-
Prevents corrosion and sludge buildup
-
Helps ensure smooth acceleration and turning
-
Extends the lifespan of your drivetrain system
We recommend checking your drivetrain and differential fluid at regular intervals—usually every 30,000 to 60,000 miles depending on your vehicle and driving habits.
