What Causes Severe Shaking When Starting a Car?
1 Answers
The reason for severe shaking when starting a car is the wear and slippage of the clutch pressure plate and disc, which can be caused by aging or quality issues. Both the pressure plate and disc need to be replaced simultaneously. Here are some related explanations for starting shake: 1. When the car shakes during startup, let the engine idle. 2. Engage a low gear, slowly release the clutch pedal, and increase the throttle to start. If the body shakes noticeably, it indicates clutch shudder. 3. Clutch shudder can also be caused by broken or loose rivets on the driven plate, fractures in the driven plate steel sheet, or unbalanced rotating components. 4. Loose engine mounts or misalignment between the transmission's first shaft and the engine crankshaft centerline can also lead to car shaking during startup.
