What Is the Drivetrain?
The drivetrain is a group of components that deliver power from your engine to the wheels. It includes the transmission, drive shaft, differential, CV joints, axles, and transfer case (for AWD/4WD vehicles). The drivetrain is responsible for transferring energy efficiently and smoothly, allowing your vehicle to accelerate, climb hills, and navigate curves with control.
Without a healthy drivetrain, your vehicle may struggle to move or even become inoperable.
What Is a Differential?
The differential allows your wheels to rotate at different speeds when you turn. Without it, your tires would skip or bind during corners, causing wear and unstable handling. Your vehicle may have one or more differentials depending on its drivetrain configuration (front-wheel drive, rear-wheel drive, all-wheel drive, or 4WD).
Signs of a failing differential include:
-
Whining or howling sounds from under the car
-
Clunking or banging noises when shifting or turning
-
Oil leaks near the differential housing
-
Excessive vibration while driving
-
Poor handling or traction
Ignoring these signs can lead to serious damage, leaving you with a costly repair or full differential replacement.
Symptoms of Drivetrain or Differential Problems
If something feels off while driving, it could be your drivetrain. Here are common signs that indicate the need for a professional diagnosis:
-
Unusual noises while accelerating or turning
-
Difficulty shifting gears
-
Fluid leaking under the vehicle
-
Vehicle shudders or vibrates when in motion
-
Trouble climbing hills or accelerating
-
Warning lights related to traction or drivetrain systems
Catching these issues early can prevent further damage to connected systems like the transmission, axles, or drive shaft.

Drive Shaft & U-Joint Repair
The drive shaft transfers torque from the transmission to the differential. It works in constant motion with the help of u-joints (universal joints) that provide flexibility as your vehicle moves.
If your drive shaft or u-joints are worn or out of balance, you may experience:
-
Loud clunking noises during acceleration or deceleration
-
Vibrations that increase with speed
-
Difficulty turning or steering
-
Clicking or squeaking sounds under the vehicle
Our team can inspect, balance, or replace your drive shaft components to eliminate noise, prevent breakdowns, and restore smooth power delivery.
Fluid Service for Drivetrain & Differentials
Like your engine, your drivetrain and differential rely on specialized lubricants to reduce friction and wear. Over time, differential and transfer case fluids can break down or become contaminated.
At M&M Car Care Center, we provide:
-
Differential fluid service
-
Transfer case fluid service
-
Front and rear axle lube changes
-
