What are the common causes of car body shaking?
2 Answers
Common causes of car body shaking are as follows: 1. Unstable oil pressure: Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can cause body shaking. Solution: Check the oil pressure and replace components if necessary. 2. Aging engine components: Car shaking can also be related to worn engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and cabin, causing shaking at idle. Solution: Replace the components. 3. Severe engine carbon buildup: Dirty throttle body or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Solution: Clean the fuel system and check if the idle control valve has carbon deposits that need cleaning.
I've been driving my small car for over two years, and recently I've noticed some body vibration when driving on the highway, which made me a bit nervous. After consulting my mechanic friend, I learned that there could be several reasons for this. For example, improper tire balancing or uneven tire pressure can cause vibrations, especially noticeable at high speeds. Additionally, aging or loose suspension components like shock absorbers can make the car unstable, and warped brake discs can cause shaking when braking. During my own inspection, I found uneven wear on the right front tire, and getting it rebalanced solved the problem. Ignoring such issues isn't just unsafe—it can also lead to wear and tear on other parts. So, if you experience vibrations, start by checking tire pressure and wear patterns. If you can't figure it out, it's best to visit a professional shop promptly. And don't skimp on regular maintenance—routine checks can save you a lot of trouble down the road.
