Why is the car shaking violently?

[Briella]

The causes of car shaking are as follows: 1. The most common reason is severe engine carbon buildup, or issues with the ignition system, or possible misalignment of the drive half-shaft. 2. If the car shakes due to severe engine carbon buildup, owners should immediately clean the fuel system and check the idle speed motor for carbon deposits. If the ignition system is faulty, they should promptly inspect the spark plugs for carbon buildup and replace them if necessary. If the drive half-shaft is misaligned, meaning it is no longer a straight shaft but bent at some point, this can also cause shaking. 3. This condition typically manifests as the car running smoothly at idle but starting to shake when driven, with the shaking becoming more severe as the vehicle speed increases. If your car exhibits these symptoms, you should check the half-shaft for issues. 4. Another phenomenon is car shaking caused by uneven brake discs. This occurs when drivers do not develop good driving habits, frequently braking hard or abruptly. In such cases, immediate repairs are also necessary.
