What Causes the Abnormal Noise in the Acceleration Drive System?
2 Answers
Acceleration drive system noise occurs due to an unbalanced drive shaft. The symptoms of an unbalanced drive shaft noise are a periodic sound heard while driving, which becomes louder as the speed increases. In severe cases, it can cause the car body to shake, and the steering wheel may feel numb when held. Main causes of the fault: The drive shaft is bent or dented, causing imbalance during operation, leading to wobbling and noise. Fault diagnosis: Lift the rear wheels of the car, start the engine, engage a high gear, and observe the vibration of the drive shaft. If the vibration is greatest when the speed decreases, it indicates that the vibration and noise are caused by drive shaft imbalance.
That annoying drivetrain noise during acceleration is really frustrating, sounding like creaking or clicking. I suspect it might be a transmission issue, such as worn gears or clutch wear, because when accelerating, the load increases and aging components start to groan. It could also be a damaged universal joint on the driveshaft, causing friction and noise during rotation. If not addressed promptly, the problem could worsen, even leading to a breakdown on the road—how dangerous. I recommend testing slow acceleration in a quiet environment when parked to listen for where the sound is coming from. If it's from the front, it might be engine-related; if from the rear, perhaps a differential issue. For safety, take it to a reliable auto repair shop as soon as possible—they can use professional tools to diagnose the issue, and once confirmed, repairs will be straightforward. Regularly changing transmission fluid and drivetrain lubricants can prevent such problems. After all, your car is your baby—don’t overlook the small details.
