Your vehicle’s drivetrain is one of the most crucial systems responsible for getting power from the engine to your wheels. Without a fully functional drivetrain, your car won’t be able to move effectively—or at all. For Subaru drivers, the advanced all-wheel-drive (AWD) system is a hallmark feature, providing exceptional traction and control. That’s why maintaining a healthy drivetrain is vital to keeping your Subaru performing at its peak. At Rallysport Engineering in Costa Mesa, CA, we’ve specialized in Subaru repair since 1982, and drivetrain repair is one of the key services we offer for our customers in Orange County and South County.
In this article, we’ll dive into what the drivetrain is, the common signs of drivetrain issues, and why Rallysport Engineering is your go-to destination for expert drivetrain repair.
What is the Drivetrain?
The drivetrain refers to the group of components that transmit power from the engine to the wheels, enabling your vehicle to move. It includes several important parts such as:
- Transmission: Changes the speed and torque of the vehicle.
- Driveshafts: Transfer power from the transmission to the wheels.
- Differentials: Distribute power to the wheels, allowing them to rotate at different speeds when turning.
- Axles: Connect the wheels to the vehicle, allowing them to rotate.
Subaru’s symmetrical all-wheel-drive system is particularly advanced, with a more balanced distribution of power that enhances handling and stability. This system is a key reason why Subaru vehicles are known for their off-road capabilities and driving precision. However, because it’s a complex system, proper maintenance and timely repairs are crucial to avoid costly issues down the road.
Common Signs of Drivetrain Problems
Like any vehicle component, the drivetrain can wear down over time or be damaged by driving habits or road conditions. Knowing the warning signs of drivetrain issues can help you catch problems early and prevent further damage. Some common signs that your drivetrain needs attention include:
- Vibrations
If you feel unusual vibrations when driving, particularly when accelerating or turning, it may be a sign that your drivetrain components—like the driveshaft—are worn or damaged. - Clunking or Knocking Noises
Strange noises, especially when shifting gears or during acceleration, can be a sign that your transmission, differential, or other drivetrain components are failing. - Difficulty Shifting Gears
If you have trouble shifting gears or notice that the transmission is slipping, this could indicate a problem within the transmission or other parts of the drivetrain. - Fluid Leaks
Drivetrains rely on transmission and differential fluids to keep components lubricated. If you notice leaks underneath your vehicle, it could be a sign that these fluids are leaking, potentially leading to serious damage if left unchecked. - Loss of Power to Wheels
If your Subaru is struggling to transfer power to the wheels, or if you experience uneven power distribution, this could indicate an issue with your differential or other parts of the drivetrain.
