What Causes Vehicle Body Shaking?
2 Answers
Body shaking is mostly related to the clutch, with specific reasons as follows: Weakened Clutch Pressure Spring Tension: When a car has been used for too long, the tension of the clutch pressure spring weakens, and cracks in the diaphragm spring can cause shaking when the clutch engages. The solution in this case is to replace the spring. Engine Idling: If the owner accidentally lets the engine idle, engages a low gear, slowly releases the clutch pedal, and accelerates to start, and the body shakes at this time, it indicates clutch shaking. Frequent Engagement of Clutch: If the clutch pressure spring tension is uneven due to frequent engagement by the owner, inconsistent adjustment of the separation levers, and/or uneven diaphragm spring separation finger ends, it can lead to unsynchronized pressure timing. Uneven force on the pressure plate will cause clutch shaking.
I just bought a car and soon encountered a problem with the body shaking. It feels like the whole car is wobbling, especially noticeable on the highway. There could be many possible reasons: wheel imbalance is the most common—if the wheels or tires are deformed or unevenly worn, this can happen; insufficient tire pressure or a punctured tire might also cause shaking; suspension system issues like damaged shock absorbers or control arms can make the car drive unsteadily; loose engine mounts or ignition system problems can also worsen shaking at low speeds; a bent or misaligned driveshaft can cause tremors at specific speeds. Last time, checking the tire pressure improved the situation, but if the suspension is damaged, it can be quite dangerous—what if an accident happens? It's advisable to go to a repair shop for a comprehensive check as soon as possible. Generally, they'll first inspect wheel balance and the suspension. When driving, pay attention to the road surface, avoid going too fast over bumps, and regular tire maintenance can prevent many issues.
