What causes slight shaking when the car is first started?
1 Answers
Possible causes of car shaking are as follows: 1. Uneven brake disc surface with excessive radial runout. This causes inconsistent contact between brake pads and discs during braking, resulting in fluctuating braking force and vehicle vibration, particularly noticeable during light braking. 2. Significant deviation in wheel alignment data. The vehicle becomes difficult to control during acceleration with slight shaking. 3. Improper tire pressure (either too high or too low). Higher speeds with overinflated tires intensify vibration, while underinflation causes vehicle drift. 4. Abnormal tire wear. Inconsistent tire surface wear due to improper wheel alignment or rim deformation leads to vibration during driving.
