Feeling about the abnormal sound of the 530 drive shaft after lifting the car for a week

August 4, 2024

I heard abnormal noises when I arrived at home the day I picked up the car.
As long as the abnormal sound does not warm up, the car will ring. When you get up in the morning, it will start to ring.
You can also hear the abnormal sound of the drive shaft when driving at low speeds. It sounds when refueling and braking. If you pass a small pit or speed bump, you can hear the “jingling” sound as long as you open the window.
The exact description ~ It’s like attaching an iron chain to a car. Wherever you go, there is a “jingling” sound caused by the friction between the iron chain and the asphalt road. Although I don’t care much, it really bothers me to hear it.
The abnormal sound of the drive shaft is definitely not a small probability event. All the three 530s I picked up on the day I picked up the car made abnormal sound! It should be an incident in which all the troops were wiped out.
A few questions about the abnormal sound of the transmission shaft?
1 Why did BMW not return the shaft to the supplier when it knew the abnormal sound, but continued to use it? Don’t foreigners ‘minds spin?
2 If BMW solved the abnormal noise problem, why did all cars produced at the end of October also make abnormal noises? Must I change the shaft once to stop ringing? Can you still let the 4s shop earn money to change shafts? This shows that BMW has not solved this problem at all! It will ring no matter how you change it!
3 If the 5 Series is replaced immediately, it will not solve the problem of the old model, but the 3 Series will not be replaced, and the ×5 will not be replaced, so there is a high probability that the new 5 Series will have abnormal noises!
