What Causes Car Shaking at Low Speeds?
3 Answers
There are several reasons why a car may shake at low speeds: 1. Unbalanced car tires: A car's wheel is an assembly consisting of a tire and a rim. However, due to manufacturing limitations, the mass distribution of this assembly may not be perfectly uniform. When the car wheel rotates at high speeds, it can create a dynamic imbalance, leading to wheel shaking and steering wheel vibration during driving. 2. Imbalance in hydraulic power unit operation: This is caused by the slow oil discharge rate (small discharge volume) from the large chamber of the oil cylinder. The reason is that the upper and lower chamber oil inlets/outlets of a single-rod double-acting piston cylinder are equipped with components such as balance valves, hydraulic locks, and throttle valves. These components are designed to control the normal operation and steady speed of the oil cylinder, ensuring the proper functioning and safe operation of the equipment.
Having driven for over twenty years, I've encountered low-speed shaking issues several times, especially noticeable in traffic jams where the car body shakes severely, affecting the driving experience. Typically, this is related to tires or suspension. Uneven tire wear, unbalanced wheels, or improper wheel alignment can all cause shaking during low-speed turns or starts. Similarly, aging suspension systems, such as failed shock absorbers, can lead to the same problem. Personally, I recommend checking tire pressure weekly to ensure balance and promptly visiting a repair shop if there are issues with suspension components. Regular maintenance can save a lot of money in the long run. Long-term neglect may lead to more serious problems, such as loss of control. Safety should never be taken lightly. Experienced drivers know that prevention is key, especially during hot and humid weather when car conditions are more prone to issues. Simple maintenance can prevent major headaches.
As an average car owner, I've been quite annoyed by the low-speed shaking while driving recently. The constant stop-and-go in the city makes the car wobble, which is not only uncomfortable but also increases fuel consumption. Common causes include engine ignition issues, such as carbon buildup or aging spark plugs, or transmission hesitation in low gears, especially with manual cars where worn clutch plates lead to unstable power delivery. Other possibilities could be dirty or uneven brake discs, indirectly causing vibrations. I suggest first checking the spark plugs and brake discs yourself—simple cleaning might help. If that doesn't work, take it to a repair shop. Don't delay, as this can accelerate fuel consumption and increase expenses. Regular maintenance, like replacing key components annually, can prevent many issues. Saving money is key, and a smooth-running car improves your mood. Don't be like me—lazy until something goes wrong, then regret it.
