What Causes Vehicle Vibration During Driving?
3 Answers
Reasons for car vibration during driving are as follows: Dirty air filter: The air filter is designed to protect the engine and reduce wear, usually requiring replacement around 10,000 kilometers. If not replaced in time, it can cause insufficient air intake, leading to low idle speed and engine vibration. Simply replacing the filter element can resolve this issue. High-voltage wire breakage: A high-voltage wire breakage refers to the breakage of the wire core inside the high-voltage wire, which can affect ignition and cause engine vibration. Use a multimeter to measure the resistance and replace the one with significantly higher resistance. Spark plug lifespan: Spark plugs have a limited lifespan. After exceeding 30,000 to 40,000 kilometers, their ignition efficiency noticeably decreases, which can affect ignition. This is the most common issue, and replacing all spark plugs can solve the problem.
Recently, while driving on the highway, my car suddenly started shaking, feeling like driving on a washboard, which was very uncomfortable. After consulting a technician, I learned that there are various reasons for this shaking. The most common issue is related to tires, such as improper wheel balancing or deformed rims, which can cause the car to shake at certain speeds. Uneven tire wear or foreign objects stuck in the tires can also cause similar symptoms. It's recommended to first perform a tire balance test and check if the tire pressure is within standard levels, as addressing this during regular maintenance usually solves the problem. If the shaking persists, it's necessary to inspect the suspension system or check if the brake discs are uneven. Regularly checking tire conditions and avoiding speeding can effectively prevent such issues, as safety always comes first.
As someone who frequently deals with car malfunctions, I've found that vehicle shaking often stems from powertrain issues. Worn-out spark plugs or carbon buildup can disrupt ignition efficiency, causing body vibrations—especially noticeable during acceleration. Damaged ignition coils or clogged fuel injectors may also lead to unstable engine operation. If accompanied by abnormal exhaust sounds, it's advisable to inspect the exhaust pipe or sensors. Simple diagnostic methods include listening for unusual engine noises or checking for warning lights on the dashboard. When encountering such problems, seek professional repair services promptly to prevent worsening vibrations that could damage other components and escalate repair costs. Timely replacement of wear-prone parts is crucial.
