What Causes Body Shaking in Small Cars at High Speeds?
2 Answers
The causes of body shaking in small cars at high speeds are as follows: Carbon Deposits in the Engine: Carbon deposits include cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, and intake carbon deposits. These areas are closely related to the engine's power output. When there is excessive carbon buildup inside the engine, the car's ignition energy decreases, intake efficiency drops, ultimately leading to reduced engine power and symptoms like shaking and poor acceleration. Fuel System Issues: Using an incompatible fuel grade can result in decreased car output power and reduced performance. Alternatively, if the fuel tank vent is blocked, it may fail to supply the required amount of fuel, leading to an overly lean air-fuel mixture and weak engine acceleration.
I experienced body shaking once while driving on the highway, which was really nerve-wracking—it felt like the car was about to fall apart. That time, it was caused by a tire issue, such as wheel imbalance, and a simple wheel balancing fixed it. It’s also important to regularly check if the tire pressure is even, as uneven pressure can cause shaking at high speeds. Another common cause is a faulty suspension system, like leaking shock absorbers or worn ball joints, which can make the body unstable. Additionally, warped or unevenly worn brake discs can worsen shaking during high-speed braking. After that repair, I became more attentive to these details. I recommend that if you notice any signs of shaking, don’t delay—get it checked at a professional shop right away. Safe driving is more important than anything else.
