What are the causes of car body shaking?
2 Answers
Body shaking is mostly related to the clutch. The specific reasons are as follows: 1. When the car has been used for too long, the elasticity 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. 2. 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. 3. If the owner frequently experiences uneven elasticity of the clutch pressure spring, inconsistent adjustment of the separation levers, and/or an uneven diaphragm spring separation finger end, it can lead to unsynchronized pressure timing. Uneven force on the pressure plate will cause clutch shaking.
I've seen plenty of cases of car body shaking, mainly caused by issues with tires, brake systems, or suspension. Things like unbalanced tires, uneven wear, or insufficient tire pressure can easily lead to vibrations, especially noticeable at high speeds. Worn brake discs or stuck calipers can also cause body tremors during braking. Additionally, aging suspension components, such as failed shock absorbers or loose control arms, can make the car unstable. I once encountered this situation while repairing a car - the owner experienced shaking on the highway, and we later found it was a front wheel balancing issue that was resolved after readjustment. To prevent such faults, it's recommended to regularly check tire pressure and condition, look for any stuck foreign objects, and perform wheel alignment in a timely manner.
