Vehicle shaking when releasing the clutch can be caused by clutch judder, uneven pressure distribution between the driving and driven discs, weakened damping spring force, or poor contact of the clutch lining. The detailed explanations are as follows: Clutch Judder: Let the engine idle, engage a low gear, slowly release the clutch pedal, and accelerate to start. If the vehicle body shakes at this time, it indicates clutch judder. Solution: Replace the clutch. Uneven Pressure Distribution Between Driving and Driven Discs: Uneven spring force of the frequently engaged clutch pressure springs, inconsistent adjustment of the release levers, and/or uneven ends of the diaphragm spring fingers can lead to asynchronous pressure application, uneven force on the pressure plate, or even tilting of the pressure plate, resulting in poor contact between the driving and driven discs and causing clutch judder. Solution: Replace the clutch pressure springs. Weakened Damping Spring Force: Weakened torsion damping spring force of the clutch, weakened force of the clutch pressure springs, or cracks in the diaphragm spring can all cause shaking when the clutch is engaged. Solution: Replace the springs. Poor Contact of Clutch Lining: Poor contact of the clutch lining, surface hardening, or adhesion of sticky substances can easily cause clutch judder. Solution: Replace the clutch lining.
