A drivetrain is a group of components located in your vehicle that transfer power created by the transmission to the wheels, enabling your Mercedes to move forward. These components include the axle shafts, U-joints, CV-joints, differentials, and driveshaft. The vehicles of today commonly possess one of four various drivetrains. These include front wheel drive (FWD), all wheel drive (AWD), rear wheel drive (RWD) and four wheel drive (4WD).
Most Mercedes models feature either all wheel drive or front wheel drive systems. FWD means that the drivetrain is located in the front of the car. This option works well for those who drive mainly on paved highways, and it normally provides better gas mileage than the alternatives. AWD allows power to be distributed to all four wheels, making it the best option for traveling on rough terrain or driving on snow or ice.
Common Signs of A Bad Drivetrain
Issues While Turning
If you notice issues while trying to turn your vehicle, you could be experiencing a faulty driveshaft. When this component begins to fail, the wheels can become less responsive. This causes a dangerous driving situation for you, your passengers, and those around you.
Vehicle Bucks When You Accelerate
When you accelerate, your car should move forward smoothly. If it shudders or bucks, you may have a bad center bearing or loose U-joint. This too can cause hazardous driving conditions.
Vibrations from Under the Vehicle
One of the most common signs of a failing drivetrain can be extreme shaking coming from under your car. This is normally the result of loose U-joints which cause the intense vibrations.
Irregular or Unusual Noises
Noises such as thuds, squeaks, or clunks can indicate a bad drivetrain. The system may simply require lubrication. Conversely, there can be a more serious problem. An expert mechanic can inspect your Mercedes and determine the exact plan of action.
Leaking Transmission Fluid
The longer your vehicle shakes, vibrates, or experiences other drivetrain issues, the greater the risk of long term damage to the transmission. Driveshaft issues can lead to leaking transmission fluid. This can wreak havoc on the overall operation of your car.
Lack of Movement
If your drivetrain fails, your vehicle will not move when you try to accelerate. This occurs when the drivetrain has disconnected itself from the overall transmission system. This disconnection is normally highlighted by a loud thud. When this happens, you will have no choice but to have your Mercedes towed to an auto service center for repair.
Why do drivetrains malfunction?
In relation to drivetrain malfunctions, there are not many things that you could do to cause such a problem. Normally, you will hear or feel the symptoms listed above before a total breakdown occurs. This will give you an opportunity to have your Mercedes inspected and repaired. If you choose to neglect the warning signs, then your drivetrain may suffer devastating consequences.
