You are driving your Porsche on the highway and enjoying the deep throated rumble of the car’s engine. Then in a blink of an eye, you realize that there is a strange vibration. It begins as a mere vibration, then as you gain more momentum the vibrations become more and more uncomfortable.

What could be the reason for your car’s drivetrain’s unusual vibration or misbehavior at high speed? We’ll find out shortly! A shaking drivetrain is not normal, it is an indication that there is something wrong. If not addressed it could develop into something much bigger in the future. Here are the causes of drivetrain vibration in your Porsche at high speeds and how to solve it.

Learning About Your Porsche’s Drivetrain

Your drivetrain is one of the most important components that makes your Porsche so much fun to drive. It encompasses all parts that transmit power from the engine to the wheel including the axles, transmission, drive shaft, and differential. When these parts are well coordinated, your car gives the smooth, high-performance driving that people associate with Porsche. However, if something is wrong, then there will be vibrations, noises, or any other problem with the performance.

Possible Causes Of Drivetrain Shake

  • Unbalanced or Damaged Tires: The first and most obvious reason for a drivetrain shake is worn or misaligned tires and wheels. If the tires of your car are worn out in an uneven manner, or if they are out of balance or have a puncture, it may create some vibrations which can be mistaken for a drivetrain problem.
  • Issues with the Axles: Another possible reason is compromised or bent axles. If your Porsche strikes a pothole or curb at high speeds, this can happen. A slight bend can cause some serious vibrations in your Porsche.
  • Differential Problems: The differential assists in the distribution of power to wheels; especially during a turn. If it is damaged or low on its fluid, you might even feel more vibrations especially when accelerating or when at high speeds.
  • Wheel Alignment Issues: Misalignment of wheels also leads to instability in your Porsche when driving at very high speed. This is normally followed by unevenly worn tires and pulling to one side of the vehicle.

How to Fix Drivetrain Shaking

  • Inspect Your Tires: First, you have to look for signs of uneven wear, damage, or imbalance on your tires. Take care of your tires and if possible rotate and balance your tires. Another way of addressing the problem is by changing worn-out tires.
  • Check the Driveshaft and U-Joints: If the tires are in good condition, the next area to check is the driveshaft and its parts. A professional technician can determine whether the driveshaft or the U-joints are worn out, or whether they require replacement.
  • Examine the Axles: By just having a look at the axles, one may observe whether the axles have bent or are damaged in any way. A bent axle must be replaced to bring your Porsche to its optimal condition again.
  • Transmission and the Differential: If the drivetrain shaking continues, then it will be wise to have your transmission or differential inspected for possible wear or alignment. There may be a need to change the fluids or repair some parts.
  • Realign the Wheels: Some driveability problems stem from vibration and a good alignment can fix it. This is a cheap solution to the problem, and it will only take you a short time to have it done on your Porsche and increase its stability and handling.
