What are the symptoms of a bad axle shaft?
2 Answers
The symptoms of a bad axle shaft are: abnormal vibration occurs when the car is driving, and it can also cause abnormal noises while the car is in motion. If the axle shaft is damaged, it needs to be replaced immediately. The axle shaft is the component that transmits power to the wheels. Without the axle shaft, power cannot be transmitted to the wheels. The axle shaft may become deformed or fractured. If the axle shaft is fractured, it needs to be replaced. If it is deformed, it also requires replacement. The axle shaft has a CV joint, which is also relatively prone to damage. There is a rubber dust boot outside the CV joint. This rubber dust boot prevents dust from entering the CV joint and also prevents the lubricating oil inside the CV joint from leaking.
I've been driving for several years, and the symptoms of a bad CV axle are really annoying. Last time my car had this issue, I could always hear a creaking sound when turning, like metal scraping, especially noticeable during sharp turns. When accelerating, the whole car shook violently, even the steering wheel felt like it was jumping, with the strongest vibrations occurring between 40 to 60 km/h, making driving very uncomfortable. I also noticed oil stains near the wheels, which was grease leaking from the CV axle. The mechanic told me this problem needs immediate attention, otherwise it will accelerate tire wear and even affect the suspension system. During regular maintenance, it's important to periodically check the condition of the CV axles and replace them in time to avoid bigger expenses. Don't delay too long, or you'll not only drive uncomfortably but also spend more money.
